Plate Tectonics

Front

Why are earthquakes common in areas like California and Japan?

Back

Both areas are on the boundary of active plates, the motion of the plates causes earthquakes.

Front

Subduction zones occur on Earth where dense oceanic crust dives under more buoyant continental crust. These boundaries are characterized by a deep ocean trench next to a high continental mountain range, large numbers of earthquakes and volcanoes. All of this is further evidence for the following theories: big bang theory, theory of plate tectonics, origin of the species, theory of natural selection.

theory of plate tectonics.

Front

Types of plate boundaries: convergent, thrust, divergent, transform. Which is NOT a type?

Back

thrust

Observe this diagram of a plate boundary. One statement BEST describes what is happening.

Back

the denser ceanic crust is subducting under the less dense oceanic crust

What geological forces might be responsible for this range of mountains? Options: diverging tectonic plates, erosion of the land by the ocean, converging tectonic plates, deposition of sediments by the ocean

Back

converging tectonic plates

Where would sea floor spreading most likely occur?

Back

At divergent plate boundaries (oceanic vs. oceanic)
