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

Looking at the figure that shows world-wide earthquake distribution, the white lines represent plate boundaries. Which statement is true?

• Earthquakes always occur along plate boundaries.

• Earthquakes most frequently occur along plate boundaries.

• Earthquakes rarely occur along plate boundaries.

• Earthquakes never occur along plate boundaries.

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.
