Earths Movement - Rotation and Revolution

Rotation means to spin around a point at it's center.

​

Picture spinning a basketball on your finger.

​

Where your finger is, is the axis.

​

As the earth moves around the sun, it spins around itself.

What does Rotation mean?

​Axis

​Equator

When half the earth faces away from the sun, it is now night time on these continents.

The other half is facing the sun so in these countries it is day time.

So if it rises in the east (Japan) and then moves west, which country is the last to get daylight?​

So what is a revolution?​

​

​Orbit

​

• Imagine you are standing straight up and then you lean to the side. Try it now!!!

• This means you are tilting. The earth also tilts.

• So if the earth is facing the sun, one part is leaning towards the sun.

• The other part is tilting away from it.

• This means that although it's daylight, they are different seasons.

• The part tilting towards the sun is getting more energy/heat which means it's summer.

• What season would be the one tilting away?​
