Processes and Landforms Along Plate Boundaries

There is no formation of volcanoes in the convergence between __________.

• A. two oceanic plates

• C. oceanic and continental plates

• B. two continental plates

• D. none of these

2. When a plate is denser, it subducts toward the mantle and forms magma. This process ends up in the formation of ______.

• A. mountain range

• C. volcanoes

• B. trenches

• D. faults

Subduction is illustrated in which of the following?

• A. convergent plate boundary

• C. divergent plate boundary

• B. transform fault boundary

• D. subducting plates

Most of the Philippine Islands were once part of island arcs. This means that

along with this boundary, there once existed two ___________.

• A. converging continental plates

• C. converging oceanic plates

• B. diverging plates

• D. plates sliding past each other

In the convergence between a continental and an oceanic plate, there is subduction. Which of the following statements does NOT support this fact?

• A. One plate carries water along with it.

• C. The temperature in the mantle is higher than in the crust.

• B. One plate is denser.

• D. One plate overrides the other.

It is otherwise known as an underwater mountain.

• A. oceanic ridge

• C. hill

• B. trench

• D. volcanic island

The tall landform created when two continental plates converge is called_______.

• A. mountain range

• C. rift valley

• B. volcanic arc

• D. Oceanic ridge

A rift valley is formed simultaneously with which of the following type of plate boundary?

• A. Convergent

• C. Transform fault

• B. Divergent

• D. Both convergent and divergent

Which of the following happens when plates diverge or move away from each other?

• A. The crust is destroyed.

• C. Earth’s size changes because mountains are added on the earth’s surface.

• B. New crust is produced because magma rises, then cools off and turns into solid.

• D. The mantle rises.

It is the point where two plates meet or collide while converging.
