Earth's Revolution and Rotation
This is Earth
We all might know what happens down in Earth but what about outside in space?
Earth is the third planet from the sun and is also the planet we live on
It rotates on its axis, an invisible line that goes all the way through Earth.
The axis has a tilt of 23.4 degrees
The process of Earth spinning counter-clockwise on its axis is called a rotation
It takes the Earth 24 hours to do one full rotation. This along with the sun helps create day and night
It takes the Earth 24 hours to do one full rotation on its axis. This is what makes day and night not the Sun.
As most of you know the moon orbits around the Earth. This is what causes different moon phases
On this diagram you can see the 8 main moon phases.
When Earth orbits around the Sun while it is rotating on its axis it is called a revolution.
It takes Earth 365 days to do one full revolution around the Sun or a year.
The Seasons And What Causes Them
Now that you know what causes day, night, moon phases, and our year you might wonder....
What causes our seasons?
Well our seasons are not caused because of the clouds or anything down on Earth
The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.
When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected.
Now why don't we head back to Earth
