Which source helped the newly formed earth become a sphere in shape?

rotation around its north-south axis. 

Earth likely grew smaller as its interior melted, rock flowed, and gravity pulled in its.also it is from asterods and gravity to the sun. the sun can really die at any time it could breeng us in to the cold. but evey one knows the sun is a stare and stares are big balls of gass. with that if it does die out it will burn us all to death... but the suns gravaity pulled off everthing that it not really aport of earth and when it did that it burned it all. but that is how earth is round and not other kinds of shapes.

also sorry for my spelling.
