Season of Earth

Earth's revolution around the Sun creates the seasons. They are different in the Northern and Southern Hemispheres.

Why do we have Seasons on Earth?

Earth completes a revolution around the Sun over 365.25 days. It is this orbit, combined with the tilt on Earth's axis, which causes the seasons. The tilt, which is approximately 23.5 degrees, means that the Earth leans slightly towards the Sun.

For part of the year, the Northern Hemisphere is tilted towards the Sun. During this time, the Sun is closer to the Northern Hemisphere. This means the Northern Hemisphere is in the direct path of the Sun's energy.
