Have you ever wondered why the temperature is different in Alaska than it is in Florida? Or how it can be really hot in South Africa and really cold in Siberia, even though they’re both south of the equator? There are many reasons that climate is different all around the world, but one important thing to know is that Earth’s climate is divided into three main zones. These zones aren’t just random or based on human preferences; they’re defined by specific criteria such as latitude and altitude. Learning about these three zones will help you understand why different parts of the Earth have such varying climates.
Let’s begin with a very basic science lesson about Earth’s tilt and how it causes seasons. The axis on which our planet spins (known as its rotation axis) isn’t exactly vertical; instead, it leans slightly at an angle of 23.5 degrees from vertical or 90 degrees to horizontal (left). This means that throughout a year, each part of the planet spends a portion of its orbit tilted toward or away from the sun—and this tilt causes winter and summer weather! The region closest to either pole receives more sunlight during the summer months because its axis tilts closer to the sun when those areas are at their warmest time of year. Conversely, less sunlight reaches these areas during winter when their axis tilts away from our star as they cool off over cooler months. When we look at where people live relative to these climate zones, we can see how this information affects our lives: most people prefer living near lines called “Tropics” where temperatures stay warm almost all year round! But there are many other reasons besides just latitude for why we find ourselves living in certain climates—so now let’s explore some more complicated examples:
The Tropics lie between about 30 north and south latitude.
The Tropics lie between about 30 north and south latitude. This zone is where all the warmest places on Earth are, with temperatures reaching above 10 degrees Celsius (50 degrees Fahrenheit). They receive enough rainfall to support rainforests, but not so much as to make them too wet for human life. In fact, this area is home to more than half of all plant and animal species in existence. This region includes most of Africa, parts of Asia and South America and areas near the Equator like Indonesia, Papua New Guinea and Brazil’s Amazon Rainforest where it rains every day during most seasons!
The subtropics lie between about 30 and 45 degrees north and south latitude.
The subtropics lie between about 30 and 45 degrees north and south latitude. The region has a wide range of weather conditions, including warm summers, mild winters, high humidity and frequent rain.
These regions are generally characterized by hot summers and mild winters. Temperatures average between 65 degrees Fahrenheit (18 degrees Celsius) in the summer and 50 degrees Fahrenheit (10 degrees Celsius) in the winter.
In the Northern Hemisphere: Subtropical climates are found on either side of the equator between 15° N and 20° N; in this area there is no distinct wet season or dry season as you get further from 30°N where you end up with a tropical climate zone again!
Temperate zones lie between about 45 and 60 degrees north and south latitude.
Temperate zones lie between about 45 and 60 degrees north and south latitude. The temperature of the air in these regions is moderate, as shown by the name “temperate.” These zones have four seasons: summer, fall, winter and spring. This is because they are located near the sun’s path over Earth’s surface. The temperate zone includes most parts of North America, Europe, Asia and Africa.
Polar zones lie between 60 and 90 degrees north to south latitude.
- Polar zones lie between 60 and 90 degrees north to south latitude.
- These areas are cold, but not very cold.
The air near the equator is warmest, meaning that it holds the most water vapor. As air rises, water vapor condenses into clouds, which eventually fall to Earth as precipitation. This process is commonly known as the hydrologic cycle.
In contrast, at higher latitudes where it’s colder and less moisture exists in the atmosphere (due to lower temperatures), precipitation may occur in a frozen state—a process called freezing rain occurs when liquid droplets become supercooled in clouds due to wind shear or when they’re blown into a cloud layer that’s below freezing.
What causes Earth’s 3 main climate zones?
The three main climate zones on Earth are the tropics, temperate zones, and polar regions.
The Earth’s rotation is the primary cause of these three climate zones. The equator is the most directly affected by this phenomenon because it’s farthest from the north and south poles – which means it experiences more direct sunlight than any other part of our planet. This direct sunlight allows for intense heat to build up at this area; therefore, creating a hot tropical climate zone.
What causes climate zones?
The Earth has four main climate zones: polar, temperate, tropical and Mediterranean. Each of these is affected by the temperature of the ocean or land that it’s on, and also by global wind patterns.
The polar region gets its name from the fact that it’s always covered in snow and ice. This means that there are little to no vegetation here—and very few animals! Because there are few plants to capture carbon dioxide from the air and turn it into oxygen through photosynthesis, there isn’t much oxygen for us to breathe either.
What are the three main climate zones determined by?
The three main climate zones on Earth are determined by a variety of factors, such as proximity to the equator and location within the Northern or Southern Hemisphere. The average temperature at each latitude varies widely depending on whether it is summer or winter in any given hemisphere (which would be summer in the southern hemisphere while it’s winter in the northern hemisphere). The poles are colder than the equator because they receive little direct sunlight during their respective summers, which means there are fewer hours of daylight for plants to photosynthesize and obtain energy from.
What are the three zones?
The climate zones on Earth are separated into three major groups. The Arctic, Arctic Ocean and Greenland climates are defined by the presence of ocean water around the north pole. The Antarctic climate is found near Antarctica, with no ocean nearby. The Tropical climates are found close to the equator and experience very warm temperatures year-round.
The Northern Hemisphere has a variety of different climates that range from warm to cold depending on their distance from the Equator. This can be explained by looking at how much solar radiation they receive during different times of year.
What are the 3 latitude zones?
There’s a clear break between the tropical climate zones and the temperate climate zones. The mid-latitudes are where you’ll find the most diversity in terms of temperature, precipitation, and general weather patterns.
What are the 3 latitude zones?
The Tropic of Cancer (23°26’N) marks the boundary between tropical and subtropical climates on Earth. It’s here that we see high temperatures and low precipitation rates year-round. When you go further north or south from this zone, you’re entering an area with a seasonable climate.
Tropical climates tend to be warm year-round with little variation in temperature between seasons; however, some regions do experience rainy seasons during warmer months when equatorial winds blow from east to west across landmasses or bodies of water like oceans or lakes
What are three factors that influence climate?
- The amount of sunlight that the Earth receives
- The time of year the sunlight hits each area
- The angle at which the sunlight hits each area
What are the three types of tropical climates in the Pacific?
- Tropical savannas
- Tropical monsoon climates
- Tropical rainforests
What causes tropical regions?
Tropical regions are hot and wet, with consistent weather patterns that stay pretty much the same year-round. These areas make up around 20% of Earth’s surface area, and lie between the Tropics of Cancer and Capricorn. They’re known for their warm temperatures (which average about 20 degrees Celsius), high humidity levels, and significant amounts of rainfall throughout the year.
The location of these climates is influenced by how close they are to the equator; tropical climates are found near this imaginary line that divides the northern hemisphere from south. As you get closer to it (going towards either pole), you’ll find less daylight hours each day as well as cooler temperatures overall. In addition, tropical climates tend to be found in areas where there aren’t any mountains or large bodies of water nearby—these features can disrupt air flow patterns so much that they could interfere with temperature regulation within those areas
What are the main factors that determine Earth’s climate?
There are five main factors that determine Earth’s climate, which are:
- Latitude. This is the distance from the equator and how far north or south you are from it. The closer you are to the equator, the warmer your temperature will be because there is less land mass blocking sunlight compared with someone who lives in Canada who has snow cover throughout winter and cannot see much sunlight until spring arrives.
- Solar radiation intensity. How much solar radiation is available at any given place on Earth at a certain time of year can influence a location’s average temperature for that month or season (for example, if there were no clouds blocking out some of this heat then it would be hotter).
What are earth zones?
Earth zones are climatic regions that have a common set of characteristics. Earth zones include the tundra, boreal forest, temperate forest, tropical rainforest and desert.
Each climate zone has a specific temperature range with an average yearly temperature that falls at or below 10 degrees Celsius (50 degrees Fahrenheit).
The tundra is an area where the ground is permanently frozen and covered in snow or ice during the coldest part of winter. In some areas of the tundra, there can be permafrost (a layer of soil that remains frozen most years) that makes it difficult to grow plants or trees.
What are the three heat zones of the earth explain and draw the diagram?
The three main climate zones are the equatorial, temperate and polar. The equatorial region is hot and humid because of the warm water in the oceans around this region. The temperate regions have a milder climate with moderate temperatures and rainfall throughout the year. In contrast, polar regions have cold winters with little rainfall which makes them dry deserts (ice caps).
The diagram below shows how these three main climate zones relate to each other:
What are the three main zones of the ocean?
The three main zones of the ocean are:
- Equatorial (or tropical) zone
- Temperate zone

What are the three main zones and their latitudinal locations?
- The tropics are the zones between the equator and the Tropic of Cancer and Capricorn, respectively.
- The temperate zone is between 23.5 degrees north latitude (23.5N) and 23.5 degrees south latitude (23.5S).
- The polar or cold zone is also known as the high latitudes, which is any area north or south of 66 degrees north/south latitude (66N/66S).

- The West Coast
What are the causes of global atmospheric circulation patterns and how do they affect weather?
The Sun is the major driver of our climate. It heats up the Earth’s surface, causing atmospheric convection and winds to move in a direction that takes heat away from the equator toward the poles. This movement creates global circulation patterns, including Hadley cells (which remove heat from tropical latitudes) and polar cells (which trap heat at high latitudes).
The Earth also has an atmosphere. In addition to providing oxygen for us to breathe, it acts as a blanket by reducing temperature extremes on both sides of Earth’s surface because it’s thicker near its equator than near its poles. This means that when you go up in elevation on land, there’ll be less air above you—and less insulation—so temperatures will drop faster as you climb higher into thinner air.
What are the three basic types of precipitation?
“There are three main types of precipitation: rain, sleet and snow. Rain is the most common type of precipitation on Earth and occurs when water vapor condenses in the atmosphere to form droplets that fall to Earth. When temperatures are just below freezing, snow or sleet may fall instead.”
Which of the three climates has the most predictable weather?
This is a difficult question to answer, because all three climates have their own unique weather patterns and associated dangers.
If you live in the tropics (23 degrees north/south latitude), you may get some humid days with high temperatures, but it’s mostly sunny and dry most of the time. This can lead to strong winds and hurricanes during hurricane season (June 1-November 30). The hottest month is July while January is usually the coolest month. Tropical climates are home to some very diverse ecosystems such as mangroves, rain forests and coral reefs that help protect coasts from storms and flooding by absorbing energy before they reach land.
Tropical Climates also tend to have higher rainfall amounts than any other climate zone due to warm air lifting water vapor into clouds where it gets condensed into precipitation (rain). In fact, if you live in one of these zones then there’s no guarantee what kind of weather will come next – it could be anything!
What are the three types of environments that are found in the tropical latitudes?
Tropical climates are the most diverse and variable climates on Earth. The temperature is near to or higher than 30°C, year-round. There are three types of environments found in tropical latitudes:
- Tropical forests
Tropical forests are found in areas with high rainfall and warm temperatures. These forests contain many different species of plants and animals, including some that you might not find anywhere else on Earth!
- Tropical savannas
The savanna climate is similar to a desert climate, but there’s more rain (between 100–250 cm) during the “rainy season”. It has lots of grasses, trees and other plants living on it – this makes it easier for animals like lions or zebras to survive here too!
What causes equatorial climate?
- The equatorial climate is the warmest and most stable climate zone, where it doesn’t get too hot or cold. There are two main reasons for this:
- The equator is closer to the sun, so it gets most of the direct sunlight you get from the Sun (the energy we receive from the sun).
- The Earth spins on an axis that’s tilted about 23 degrees relative to its orbit around the Sun. This angle means that some areas are in direct sunlight 24 hours a day (like at your home on Earth), while others might have nighttime conditions throughout most of their year (like places near Earth’s poles).
This makes equatorial climates more stable and predictable because they don’t experience drastic changes like those found in other climate zones.
What causes wet and dry seasons in the tropics?
So what causes wet and dry seasons in the tropics? It’s a combination of factors. One factor is the distance of the sun from Earth. The closer to the equator, the less solar energy you get (because it’s directly overhead). This means that tropical climates generally receive less solar radiation than temperate climates at similar latitudes (for example, London has more hours of sunlight than Berlin).
Another factor is air pressure. Air pressure depends on where your are relative to other areas on Earth, so we often hear about high-pressure systems bringing clear weather with light winds and low humidity. Low-pressure systems bring cloudier skies with stronger winds and higher humidity, which would make it feel humid even if there was no rain falling from clouds!
Which of the following is the reason why temperatures are highest in the tropical zone?
- The sun is directly overhead in this region.
- Heat from the ocean is trapped by the atmosphere.
- The amount of water vapor in the air increases as you move away from the equator and closer to the poles.
What causes a tropical wet climate?
Tropical wet climates are found in the equatorial regions of the world. They have high temperature and humidity, with relatively low annual rainfall. The climate is dominated by the moist oceanic trade winds which bring moisture from the ocean to land. As these winds move over tropical landmasses such as Indonesia and Malaysia, they force air up into higher levels of the atmosphere where it cools and condenses water vapor into clouds and rain before raining back down onto Earth as precipitation (rain or snow). The most famous example of a tropical wet climate is Singapore where nearly every day between November and March is hot and humid with rain likely at some point during those months (this makes it one of my favorite places to visit).
Which factors best determine the variety of climate zones on Earth?
Climate zones, which are areas with similar climates, can be described in terms of temperature, precipitation, and vegetation. The polar climate zone is found at both poles. It has a mean annual temperature below -60 degrees centigrade (-76 degrees Fahrenheit), a mean annual precipitation of less than 50 cm (about 20 inches), and no vegetation. The tundra climate zone lies just south of the polar climate zone and has a mean annual temperature from -50 to -30 degrees centigrade (-58 to -22 degrees Fahrenheit). The tundra is cold but not as cold as the polar region; its soil thaws during summer months so that some plants can grow there.
The temperate regions have mild summers with hot days and cool nights or cool summers with warm days and cool nights. Both areas have year-round precipitation—less than 25 cm (10 inches) per year in deserts, more than 25 cm (10 inches) per year in grasslands—and sufficient rainfall throughout most years for trees to grow tall enough to intercept sunlight above their canopy level.
Which three major climate zones are most closely related to latitude?
The climate zones are tropical, temperate and polar.
The tropics are found near the equator where temperatures are warm all year round. The temperature does not vary much throughout the year, so it rarely gets too hot or cold. Tropical areas tend to be humid with lots of rain and sunshine all year round.
Because there is no real seasonal variation in temperature here, there is also less variation in day length – this means that plants can grow and flower at any time of year without needing to adapt their growth to different seasons each year (like they would do further north or south).
What are the three main types of climate in West Africa?
In West Africa, the climate can be divided into three main types:
- Tropical monsoon climate
- Dry and arid
- Tropical savanna
What are the three heat zones of the earth and why does the Torrid Zone receive the maximum amount of heat?
The first thing to consider when trying to understand the three main climate zones on Earth is the energy that’s coming in from the Sun. The amount of energy the Sun can give us depends on how close it is to us, but also on its own size and brightness.
The Earth’s orbit around the Sun isn’t perfectly circular – it actually takes about 365 days for us to make one complete orbit. But because our planet isn’t a perfect sphere, it turns out that at some points during its yearly journey around our star, we’re closer than others. When we’re closest, or perihelion (pronounced “purr AY HEEL un”), we receive more solar radiation; when we’re farthest away at aphelion (“apuh EH LEE un”), which occurs every 2 years and 10 months or so as well as every year between February 4th and March 5th (depending on where you live), we get less solar energy due to being further away from our sun!
Why is the earth divided into zones with different temperatures?
The earth is divided into three main climate zones, as well as many smaller ones. These zones are:
- The Tropical Zone, which includes most of the land and water bodies on Earth that are located between 23 degrees north and south latitude (including Africa, Australia and South America).
- The Temperate Zone, which includes Europe, North America and parts of Asia (excluding Siberia) as well as southern Australia and southern South America.
- The Polar Zone or Ice Caps, which include areas around the North Pole and South Pole where there is always ice because temperatures never rise above freezing point
Why are the temperate zone also called heat zone?
Heat is a condition of warmness, which is produced when we are exposed to the sun’s rays. The sun warms up the land, water and air. The land then cools down as it loses heat through radiation at night. This causes a difference in temperature between day and night called diurnal variation of temperature (DVT). It’s called heat because of this DVT which in turn causes high atmospheric pressure above due to the heating effect from below by sunlight.
In this post, I’ve gone over all three of the main climate zones on Earth. We covered what defines each zone, how the Sun’s heat affects the climate in that zone, how global wind patterns affect the climate in that zone, and how ocean currents affect the temperature in that zone. We also talked about how you can use weather conditions to narrow down your possible location on Earth if you were lost with no other information available. Next up, we’ll dive into what causes rain, snow and other precipitation!
