Earth

=Earth=

The Earth is a sphere surrounded by air and a small amount of water, this is called the atmosphere. Outside the atmosphere it is called space which is a vacume.
**The Earth's Structure**

__The Earth's structure__ is three layers. The very outside layer is the crust which is thin, then the mantle then the core which is the very centre of the Earth.
**Earth's Moon and Rotations/Orbits** The Earth has its very own __Moon__ that is much smaller and orbits around us. While the Moon orbits Earth it rotates on its axis. Much like the Earth, while the Earth is orbiting the sun(in a anti clock wise direction), it is rotating on its axis. **Earth's Axis and Seasons**

=
The Earth's axis is about 23.5 degrees. Earth's axis causes __Earth's seasons__. There are some places on Earth that get an exact overhead sun in the June and December solstices. These places are exactly half way the equator and the poles. They are called the Tropic of Cancer( in the northern hemisphere) and the Tropic of Capricorn(in the southern hemisphere). The equator is the line that splits the world in half.======

**Sun Set and Rise**

=
The reason it looks like the sun is setting and rising is because of the rotation when the Earth rotates it shows different sides to sun. The sun does not orbit the Earth the sun orbits the centre of the universe.======
