Seasons



What does earth's constant rotation cause us to experience? We do not feel any motion. Everything stays in place because the Earth pulls everything to itself. This pull is called gravity.

How long does it take earth to complete one rotation? Earth spins around one time, or makes one full rotation, in 24 hours.

From which direction does the sun rise ? People at point A can see the sun rise. (north)

From which direction does the sun set? When the people are at C, the sun is going down. This means it is sunset.(south)

What do you think would happen if the Earth stopped rotating? There would be no sun for a certain part of the world.

How would this effect human life? The crops on one side of the earth would die from not having sun light.

Concept about Earth's rotation: Light from the sun falls on one half of the spinning Earth. This half has day. The other, darker half has night.
