_____________ is when two plates move toward each other.

• Convergent boundary
• Allegiant boundary
• Transform boundary
• Sliding boundary

A _____________ is when two plates move past each other in opposite directions.

• emergent boundary
• divergent boundary
• transform boundary
• convergent boundary

The movement of the tectonic plates is caused by

• 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.
