Convection Plate Tectonics

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.

Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that

• the oceanic crust is melting.

• the denser ceanic crust is subducting under the less dense oceanic crust

• volcanic islands are forming.

• the tectonic plates are moving away from each other.
