Plate Tectonics

Which statement best describes the continental and oceanic

crusts?

• The continental crust is thicker and less dense than the oceanic crust.

• The continental crust is thinner and more dense than the oceanic crust.

• The continental crust is thinner and less dense than the oceanic crust.

• The continental crust is thicker and more dense than the oceanic crust.

Recent volcanic activity in different parts of the world supports the inference that volcanoes are located mainly in

• the central regions of continents

• zones of crustal activity

• zones in late stages of erosion

• the centers of landscape regions
