Plate Tectonics

The movement of the tectonic plates is caused by

• the rotation of the Earth.

• convection currents in the Asthenosphere

• the gravity of the iron-nickel core.

• the Moho discontinuity.

In some areas of the world, like California and Japan, earthquakes are a common occurrence. How can this best be explained?

• The strong ocean currents are undermining both areas causing earthquakes.

• Both areas are located near the edge of the Pacific Ocean, the unstable sand causes earthquakes.

• Both areas are subjected to strong ocean wind and waves that causes earthquakes.

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

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

• the oceanic crust is melting.

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

• volcanic islands are forming.

• the tectonic plates are moving away from each other.

Earthquake epicenters (center of where the earthquakes started) were mapped for a 35 year period in the diagram above. The black dots indicate these epicenters. The black dots appear along what feature on Earth?

• hot spots

• plate boundaries

• rift zones

• sea floor spreading

The Earth’s surface is not a solid surface but is divided into

• several oceanic plates.
• continental and crustal plates.
  
• seven continental plates.
• continental and oceanic plates.

A plate boundary where two plates move away from each other is called

• Divergent Boundary
• Convergent Boundary
• Transform Boundary
• Subduction

Scientists hypothesize that a super continent existed 200 million years ago.  This continent is called

• America
• Super Earth
• Pangea
• Eurasia
