Question

What is the force that make earth move and how??

Answer 1

At the centre of the earth is a huge ball of liquid iron. It is always spinning and causes the earth to spin with it. Every few million/billion years the iron core shifts its direction of spin. When it does, the entire eco-system could be wiped out (if it's a big enough shift). Mega tsunamis, total change of weather systems, etc. Antartica could end up in the tropics.
