13.3 Plate Boundaries Quiz

Which theory states that Earth’s crust and rigid upper mantle move in different directions and at different rates over Earth’s surface?

• ridge push and slab pull

• plate tectonics

• seafloor spreading

• continental drift

Tectonic plates interact at places called plate

• regions

• subductions

• boundaries

• reversals

Places where tectonic plates move apart are called

• convergent boundaries

• divergent boundaries

• subduction zones

• transform boundaries

The Mid-Atlantic Ridge is an example of a

• transform boundary.

• subduction zone.

• convergent boundary.

• divergent boundary.

Places where tectonic plates come together are called

• divergent boundaries.

• transform boundaries.

• rift valleys.

• convergent boundaries.

Oceanic crust is made mostly of

• sediments.

• water.

• granite.

• basalt.

What can happen when two oceanic plates converge, and one is subducted into the mantle?

• The lithosphere splits to create a divergent plate boundary on land.

• A continent splits to form a new ocean basin.

• The colliding plate edges become crumpled to form a mountain range.

• Magma erupts and forms an arc of islands.

Which feature is associated with a continental-continental plate boundary?

• a mountain range

• a volcano

• a deep-sea trench

• a subduction zone
