When the earth was large enough, it is believed to

have separated into layers with the densest layer in

the center (the core), the next dense layer in the

middle (the mantle), and the least dense layer at

the surface (the crust). What force caused earth's

elements and compounds to separate into layers?

A gravity

B impacts from planetesimals

c heat from the decay of

radioactive elements

D all of the above
