Earth’s North and South poles (magnetic fields) are due to its liquid outer core.

Its mantle makes up 85% off earth’s volume.

The mantle is 1800km thick.

Tectonic plates move as slow as a nail grows.

Earth is the only planet which has water on its surface.

All the continents were combined together to form one big gigantic continent, called Pangea 200 million years ago!

Mount Everest is the highest peak- at 8,850 metres above sea levels.

Temperature of mantle can reach from 500°C at the crust to 4000°C at the core.
