• Slab push

• Ridge push

• Convection push

Which of the following is true?

• The colder the rock the less dense it is, so it rises.

• The hotter the rock the more dense it is, so it will sink.

• The colder the rock, the more dense it is, so it will sink.

• The hotter the rocks the less dense it is, so it will sink.
