Plate Tectonics, Earthquakes, Volcanoes

Scientists have measured the rate of growth of the Atlantic Ocean basin to be about 2 to 3 cm per year. This type of activity coincides with the formation of ridges on the ocean floor. What is the MOST likely cause of this activity?

• flow of continental basalt

• movement of tectonic plates

• erosion of undersea mountains

• deposition of sediment from estuaries

Oceanic crust is composed mainly of basalt. Continental crust is composed mainly of granite. Why does oceanic crust generally tend to subduct under continental crust when plates collide?

• The oceanic crust is thicker than the continental crust.

• The continental crust is thicker than oceanic crust.

• The oceanic crust is denser than the continental crust.

• The continental crust is denser than the oceanic crust
