Answering searching space questions.

I am always amazed at the questions you ask. It's fantastic although we must remember that I am no Professor Brian Cox! Like I said in class, part of the TASC wheel process is to research the answers to your questions. I have found the answer to Friday's question;"Why does the earth spin?"



Why does Earth spin?

Earth spins because of the way it was formed. Our solar system formed about 4.6 billion years ago when a huge cloud of gas and dust started to collapse under its own gravity. As the cloud collapsed, it started to spin. Some of the material within this cloud gathered into swirling eddies and eventually formed into planets. As the planets formed they kept this spinning motion. This is similar to what you see when skaters pull in their arms and spin faster. As material gathered in more closely to form a planet, like Earth, the material spun faster. The Earth keeps on spinning because there are no forces acting to stop it
