How does the earth spin on it's axis?

Answer 1

Earth rotates because of leftover momentum from the solar nebula that all of the planets and the Sun formed within. The solar nebula collapsed when a supernova sent a shock through a cold cloud of molecular hydrogen. Each molecule in the cloud had its own momentum, and as they came together, their momentums added up, and needed to be conserved. This set the solar nebula spinning, and created the planetary disk.

Answer 2

the earth spins because inside the earths core lies some magma that is so hot that the chemical process makes it belch out steeming hot magnesium oxide (MgO). it then circulates in the mantle of the earth and becomes so carbonated that it creates an energy, which, when mixes with calcium oxide, creeated a natural made engine, which makes the earth spin round.

this answer is great for homework and school projects, so if you have anymore questions concerning your school work, please dont hesitate to ask. thank you. xxx
