Why does the continental crust rise over the oceanic crust?

• The continental crust is less dense.

• The oceanic crust is thinner.

• The continental crust is not made of granite.

• The oceanic crust is younger.

The Appalachian Mountains were formed when

• volcanoes erupted

• landmasses split

• landmasses came together

• earthquakes happened

What are the puzzle pieces of the Earth's surface called?

• Tectonic plates

• Puzzles

• Earthquakes

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.
