new ocean crust forms along which boundary type

The movement of the tectonic plates is caused by
the rotation of the Earth.
convection currents in the mantle
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.
The map in the picture shows tectonic plate boundaries. This map would be useful in predicting the location of future
droughts
hurricanes
earthquakes
tornadoes
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
Where are earthquakes MOST LIKELY to occur?
close to the equator
close to the center of tectonic plates
at divergent or convergent plate boundaries
at transform plate boundaries
The 2004 Indian Ocean tsunami was caused by a shift in two plates that pushed one section of the sea floor under another section of the sea floor by 5 meters. What type of boundary is this?
divergent
convergent
transform
metamorphic
What is the source of energy that drives plate movement?
the subducton of the sea floor
the different densities of the oceanic and crustal plates
convection currents in the asthenosphere
the friction force between the plates that move past each other
