Have you ever wondered about the changes in weather that happen at the same times every year? The reason lies in the seasons. Learn what the seasons are, why they happen, and how they're different in other parts of the world with this lesson. Updated: 10/20/2020

What Are the Seasons?

The seasons are four different times during the year with different types of weather. The four seasons are called spring, summer, autumn, and winter. Seasons change throughout the year because of the way the earth moves. The earth orbits, or travels around, the sun. As it orbits, it spins on its own axis, too. Imagine there was a straight pole that went through the center of the earth, from the North Pole to the South Pole; this is the earth's axis.

But the earth's axis doesn't go straight up and down. The earth actually tilts to the side, so as it rotates around the sun, half of the earth is leaning toward the sun and half is leaning away. Earth's orbit, its rotation on its axis, and its tilt are all reasons for the four seasons!

Let's take a look at each season as it is experienced in the U.S.

Because Earth is tilted, sunlight is stronger at different times of the year

North America's Four Seasons


Spring in the U.S. begins around the 21st of March and ends around the 21st of June. It's the time of year when sunlight gets stronger because the angle of the sun gets higher. Days in spring get longer, and weather becomes warmer. You'll notice that trees begin to grow flower buds and leaves, and animals come out of hibernation. Spring often sees a lot of rain, too, giving new plants and flowers the water they need to grow.


Summer is the hottest time of the year in North America. From around June 21st to September 21st, the Sun is at its highest point in the sky and days get very warm. Plants have fully grown leaves and flowers are in full bloom. The weather tends to be a bit drier during this time of year, though thunderstorms can bring heavy rain.

Additional Activities

Matching Game for Learning the Four Seasons


  • The four seasons are spring, summer, autumn, and winter.
  • Spring is characterized by the weather beginning to warm up, and flowers and trees beginning to bloom.
  • Summer is characterized by the warmest season/weather, and flowers and trees are in full bloom.
  • Autumn is characterized by the weather beginning to cool, flowers begin to decrease, and the leaves on the trees changing color.
  • Winter is characterized by the coldest season/weather, no flowers, and trees no longer have their leaves. This is also when it is most likely to snow in areas that get snow.

Matching Game Directions

For each of the following scenarios and phenomena, match with the season it is most likely to happen in, and explain why.

Scenarios and Phenomena

  1. Susie is getting ready, and based on the weather, she decides to wear a tank top and shorts for the day.
  2. Dave looks out the window, and the big tree in his yard is a beautiful hue of red.
  3. Reggie turns on the heat in his house for the first time since last March.
  4. Sara and Missy build a snowman.
  5. Donnie is noticing that his flower garden is just starting to bloom.
  6. Margot dresses for the weather in a thermal top under a big sweater and long underwear under her jeans.


  1. Summer, because it is the hottest season, so it is the most likely season to wear shorts and a tank top.
  2. Autumn, because this is when the leaves on the trees change colors.
  3. Autumn, because this is when the weather begins to get cooler.
  4. Winter, because this is when it is most likely to snow in areas that get snow.
  5. Spring, because this is when flowers begin to bloom.
  6. Winter, because it is the coldest season, so it is the most likely season to wear thermal clothes underneath regular clothes.
