Transcript of Planet Earth

Earth's Plates
Its surface is split into plates (tectonic plates)

The plates float on a rocky mantle-the layer between the surface of Earth, its crust, & its hot liquid core.

The inside of Earth is active which is why earthquakes, volcanoes, and mountain building take place

The Earth has fewer craters than the surface of other planets
Unique Earth

Earth comes between Venus and Mars

The side that faces the Sun has daytime

The side that faces away from the Sun has night-time

As it orbits round the Sun it tilts very slightly, giving us our Seasons.
