What happens during Earth’s orbit around the Sun?
Different parts of the Earth’s surface are tilted towards the sun. This influences the seasons and length of the day and night.
What happens during the summer?
The northern hemisphere is tilted towards the sun. Days are long and we receive more solar radiation.
What happens during autumn?
The northern hemisphere begins to tilt away from the sun. Days get shorter and temperatures drop as we receive less solar radiation.
