Shaping Earth's Surface

What type of mountains are formed when molten rock erupts onto Earth’s surface and hardens?

• uplifted mountains

• fold mountains

• volcanic mountains

• fault-block mountains

Volcanoes can form over a plume, or rising current of hot mantle. As a tectonic plate slowly moves over a plume, a volcano will form and then become extinct as it moves away from the hot spot. Then the next volcano will form. If the hot spot shown made all the islands in the figure, is the plate pictured below moving toward you or away from you?

• The plate is moving toward me.

• The plate is moving away from me.

• There is no way to tell.

• It is stationary

Look at the figures showing the distribution of volcanoes and earthquakes. Why do volcanoes and earthquakes occur in so many of the same areas?

• Both often occur near plate boundaries

• Both are formed by magma

• They can only occur near mid ocean ridges

• Earthquakes create volcanoes

If 2 oceanic plates collide, which one will subduct?

• The plate that is more dense

• The plate that is least dense

• The one with the fewest people on it

• Neither. They will create a fold mountain.
