Which best explains why earthquakes sometimes occur in the same locations as mid-ocean ridges and rift valleys?

A
Plates bump as they slip past each other at convergent boundaries.
B
Plates get stuck as they move past each other at convergent boundaries.
C
Crust gets cracked and forms faults as plates collide along divergent plate boundaries.
D
Faults form because crust gets cracked when plates move apart along divergent plate boundaries.

Many more earthquakes occur along the San Andreas Fault in California than in other parts of the United States. Scientists claim that these earthquakes are caused by activity along a transform plate boundary.Which evidence would best support this claim?

A
Subduction causes new crust to form.
B
Subduction causes old crust to be destroyed.
C
Plates slip past each other at the boundary.
D
Plates collide with each other at the boundary.

Which statement explains the relationship between the density of a material and its movement in Earth’s interior?

A
Cooler materials move from Earth’s mantle to the lithosphere.
B
Cooler materials are highly dense, causing them to sink to the outer core.
C
Warmer materials sink to the mantle because their density slowly decreases.
D
Warmer materials have a high density, causing them to rise to Earth’s surface.
