We have four seasons every year: Winter, spring, summer, and fall. All of these seasons are defined by different weather patterns and temperatures. For example, summer is hot and sunny, and winters are cold, cloudy, and snowy.

But what causes seasons? To put it short, seasons are caused by the Earth’s tilt towards the sun. Every year, the Earth tilts on its axis towards, and away from the sun.

The earth is split into two hemispheres: the northern and the southern hemisphere. The Northern hemisphere is the top half of the Earth and the southern hemisphere is the bottom half of the Earth. When the Northern hemisphere is tilted towards the sun, it will be warmer weather, and when it is tilted away, it will be colder.

The tips of the Earth called the North and the South pole are cold because they never get direct sunlight. In the same way, the areas next to the equator, which is an imaginary line drawn halfway horizontally around the Earth are usually always warm because they get constant sunlight no matter which way the Earth’s axis tilts.
