Have you ever wondered why some places on Earth are warm while others are cold? For example, why doesn’t it get very cold in Southern California, but just one state away in Nevada, it can snow? Or why is it super hot in Arizona during the summer but not very cold in the winter? And why is it freezing at the North and South Poles but always warm in Hawaii?
The answer to these questions is climate. Climate is the usual weather pattern in a place over a long time. It’s different from weather, which can change from day to day or even hour to hour. Climate changes very slowly, sometimes taking thousands of years to change.
There are three main types of climates in the world: Arctic, tropical, and temperate.
The Arctic climate is found near the North and South Poles. It has long, cold winters and short, cool summers. The sun’s position affects how cold or warm a place is. In the Arctic, the sun doesn’t shine directly, making it colder than other places. Even in summer, the sun is low in the sky, and in winter, it disappears for months!
Polar climates are part of the Arctic and Antarctic regions. These areas are too cold to support much life, especially in Antarctica, where it never gets above freezing. However, in the Arctic, temperatures can rise above freezing for a short time, allowing ice to melt.
If you prefer warmth, a tropical climate might be more appealing. Tropical climates are found near the Equator and are known for being warm and rainy, especially in summer. Even in winter, it stays warm.
Places like the Congo in Africa and the Amazon in Brazil have tropical climates. There are two types of tropical climates: equatorial and desert. Equatorial climates, like those in Fiji and Samoa, are warm and rainy all year. Desert climates, found in places like the Sahara Desert, are hot and dry with little rain.
If you don’t like extreme temperatures, a temperate climate might be just right. In temperate climates, it doesn’t get too hot or too cold. Most of Canada, Europe, and parts of Australia have temperate climates.
There are warm and cool temperate climates. Warm climates have mild, wet winters and hot, dry summers, like in Southern California. Cool climates have cold winters and warm summers, like in the British Isles.
Two major factors that affect climate are how close a place is to the ocean and its elevation above sea level. Higher places are colder, while lower places are warmer. For example, climbing a mountain in a warm area will get cooler as you go up.
Oceans also play a role by absorbing heat from the sun, making coastal areas warmer. Winds can also change the climate by bringing hot or cold air.
Seasons affect climate too. Some places have different weather patterns throughout the year, while others stay the same. Long ago, during the Ice Age, the Earth’s climate was much cooler, with ice covering large parts of the northern hemisphere.
Climate can change over long periods due to things like volcanic eruptions, changes in Earth’s orbit, and the sun’s energy. Many scientists believe human activities, like building cities, cutting down forests, and pollution, contribute to climate change.
Now that you’ve learned about different climates, can you guess what type of climate you live in?
Create a map of the world and label the different climate zones: Arctic, tropical, and temperate. Use colors to differentiate each zone. Research and mark at least two countries or regions within each climate zone. This will help you visualize where these climates are located globally.
Write a short paragraph comparing weather and climate. Include examples of how weather can change daily, while climate is the average weather over a long period. Share your paragraph with a classmate and discuss the differences.
Conduct a simple experiment to understand how elevation affects temperature. Use a thermometer to measure the temperature at ground level and then at a higher elevation, like a hill or a tall building. Record your findings and explain how elevation impacts climate.
Participate in a role-playing activity where you debate the causes and effects of climate change. Take on roles such as scientists, environmentalists, or industry representatives. Discuss how human activities might contribute to climate change and propose solutions.
Keep a weather journal for one month, recording daily weather conditions such as temperature, precipitation, and wind. At the end of the month, analyze your data to identify any patterns and discuss how these patterns relate to your local climate and seasons.

Do you ever wonder why some areas on Earth are warm and others are cold? Why doesn’t it get very cold in Southern California, but one state away in Nevada it gets cold enough to snow? Why does it get so hot in the summer in Arizona but not very cold in winter? Why is it freezing cold at the North and South Poles but always warm in Hawaii?
The answer is climate. Climate refers to an area’s normal weather pattern over a long period of time. It is different from weather, which changes from day to day or even from one hour to the next. Climate changes very little, and if it does, it may take thousands of years for that change to take place.
There are three main climates in our world: Arctic, tropical, and temperate. Arctic areas are located near the North and South Poles. The climate of the Arctic region consists of long, cold winters and short, cool summers. There is a lot of variation in the climate across the Arctic, but all of it is very cold. The position of the sun has a lot to do with climate and whether it is mild, freezing, or hot. Because the Arctic does not get direct sunlight, it is colder there than in other places on Earth. Even in the middle of summer, the sun sits lower on the horizon in the Arctic than in other areas of the world. In winter, the sun is far below the horizon and cannot be seen for months at a time.
Within the Arctic and Antarctic are polar climates. These climates do not support life in the Antarctic or South Pole, where the temperature is much colder than at the North Pole. In fact, it never gets above freezing there. However, for a short time, temperatures in the Arctic or North Pole may rise above freezing, allowing the ice to melt.
Just south of the Arctic Circle, there are sub-arctic areas, including Greenland, Alaska, Northern Canada, and parts of Scandinavia and Siberia. In winter, temperatures are below zero, and rivers and lakes are frozen. But in summer, when temperatures rise above freezing, the ice melts, and plants that grow on the tundra can support some animal life.
If you don’t like being cold or living where there isn’t sunlight for long periods, then the Arctic is not the place for you. Instead, you may prefer a tropical climate. A tropical climate is found in tropical regions, just north and south of the Equator. Tropical climates are non-arid, meaning they receive a lot of rain, especially in the summertime. The temperatures are very warm in tropical climates, even in winter, when there is less rain.
The Congo in West Africa and the Amazon in Brazil are examples of tropical climates, as well as some rainforests in Malaysia and Indonesia. There are two types of tropical climates: equatorial and desert. Equatorial climates run along the Equator, where temperatures are warm year-round, and rainfall occurs all year as well. During summer, it gets very hot and humid, with thunderstorms accompanying the rain. Fiji, Samoa, and Tonga are examples of equatorial climates.
Desert climates are very dry and hot, receiving very little or no rain at all. They are found in North Africa, such as the Sahara Desert, in Arabia, and in parts of Australia. If you don’t like the idea of living in a very cold Arctic climate or a very hot tropical climate, then perhaps you need something in the middle: a temperate climate. In a temperate climate, it doesn’t get very hot or very cold; instead, the temperature usually stays about the same.
Most of Canada, Europe, Central Asia, and southern parts of Australia and South America have temperate climates. There are two categories of temperate climates: warm and cool. In warm climates, winters are usually mild and wet, while summers are hot and dry. Some areas of Chile and Argentina, as well as Southern California, are examples of warm climates. The Mediterranean region, including Greece and parts of France, Italy, and Spain, also has warm climates.
In cool climates, winters are cold and summers are warm. The winter months have snow and freezing temperatures for short periods, and there is less rain in summer than in winter. Examples of cool climates include the British Isles, northern Europe, and New Zealand.
Two major contributors to an area’s climate are its proximity to the ocean and its elevation above sea level. The higher the elevation, the colder the climate; the lower the elevation, the warmer the climate. For example, if you were to climb a mountain in a warm area, the higher you go, the cooler it becomes, and the climate is no longer a warm one.
Oceans and seas affect climates too by absorbing heat from the sun, which is why it’s warmer near the coast and cooler further away. Hot or cold winds also affect the climate. Climates can vary drastically within a single country. The United States is one example: Hawaii has a tropical climate, Alaska is part of the subarctic climate, and within the other 48 states, there are desert areas, rainy areas, and dry climates. The warmest areas in the United States are in the southwest, while the cooler areas are in the north.
Seasons also affect the climate of an area. Some areas experience a wide range of weather patterns throughout the year, while others maintain a more consistent temperature. Climates can change over long periods of time. Thousands of years ago, the entire climate of the Earth was much cooler than it is now, during a period known as the Ice Age. The ice caps or glaciers covering the North Pole extended nearly across the entire northern hemisphere of the Earth.
Several reasons contribute to climate change over long periods, including volcanic eruptions, the Earth’s orbit around the sun, and how much energy the sun sends to the Earth. Other forces can also affect climate change. Many scientists believe human behavior causes climate changes, and that activities like building large cities, cutting down forests, pollution, and natural gas extraction all contribute to climate change.
Based on what you’ve learned today, can you guess what type of climate you live in?
