Mountains and Plates

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.

What can cause a chain of volcanic islands to form far from plate boundaries?

• rifting

• folding

• hot spots

• subduction

This diagram shows a subduction zone. What type of plate boundary is shown in the image, and what type of landform is likely to occur here?

• divergent boundary; a trench

• convergent boundary; continental volcanic arc

• divergent boundary; island volcanic arc

• convergent boundary; folded mountains

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.

This diagram shows how a volcanic island arc forms. Which types of tectonic plates are found at an island arc? AND name the type of plate boundary shown.

• 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
