A
transform boundary between two ocean plates
B
transform boundary between two continental plates

convergent boundary between two ocean plates
D
convergent boundary between two continental plates

A
on land but close to oceans
B
inland, far from the coast

6

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.
