Why are there 4 seasons?• The Earth orbits around the Sun • It takes one year to complete one round • The angle of the Sun’s rays creates different

temperatures across the Earth

Do seasons happen at the same time all over the world?

• No, they don’t.• The Earth is divided by an imaginary line called

the Equator. When it’s winter in the northren hemisphere, it’s summer in the southern hemisphere and when it’s winter in the southern hemisphere it’s summer in the northern.
