Earth's Revolution and Rotation
00:19
This is Earth
00:23
We all might know what happens down in Earth but what about outside in space?
00:30
Earth is the  third planet from the sun and is  also the planet  we live on
00:36
It rotates on its axis, an  invisible line that goes  all the way through Earth.
00:38
The axis has a tilt of 23.4 degrees
00:43
The process of Earth spinning counter-clockwise on its axis is called a rotation
00:48
It takes the Earth 24 hours to do one full rotation. This along with the sun helps create day and night
00:48
It takes the Earth 24 hours to do one full rotation on its axis. This is what makes day and night not the Sun.
00:55
As most of you know the moon orbits around the Earth. This is what causes different moon phases
00:58
On this diagram you can see the 8 main moon phases.
01:04
When Earth orbits around the Sun  while it is rotating on its axis it is called a revolution.
01:08
It takes Earth 365 days to do one full  revolution around the Sun or a year.
01:14
The Seasons  And What Causes Them
01:18
Now that you know what causes  day, night, moon phases, and our  year you might wonder....
01:22
What causes our seasons?
01:24
Well our seasons are not caused because of the clouds or anything down on Earth
01:31
The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. 
01:36
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.
01:43
Now why don't we head back to Earth
01:54
