Forces and Landforms at Plate Boundaries

Why do folded mountain belts sometimes form at convergent plate boundaries?

• because rock is compressed and forced upward.

• because convergent plate boundaries occur above hot spots.

• because the rock is stretched apart and breaks, which allows magma to rise to Earth's surface.

• because subducted oceanic lithosphere melts and rises as magma to Earth's surface.

On which type of plate would you find thinner, denser rock?

• oceanic plate

• continental plate

• lithosphere plate

• rocks on all plates have the same thickness and density.

• oceanic plate and oceanic plate; convergent boundary

• oceanic plate and oceanic plate; divergent boundary

• oceanic plate and continental plate; convergent boundary

• oceanic plate and continental plate; divergent boundary
