Where would you be most likely to find a trench formed?

• the convergent boundary of two oceanic crusts

• the divergent boundary of two continental crusts

• along fault lines in California

• at the subduction zone where oceanic and continental crusts converge.

Off the coast of South America along the Peru-Chile trench, the oceanic Nazca plate is being pushed under the continental South American plate. As a result, the South American plate is being lifted up. Which landform is being created along these plate boundaries?

• The Nazca Plate will slide under the South American Plate and lead to volcano formation.

• The Nazca Plate will slide under the South American Plate and form a rift valley.

• The two plates will slide away from each other and form a mid-ocean ridge.

• The two plates will slide away from each other and lead to earthquakes.

Volcanoes often form at convergent plate boundaries. Which set of arrows represents a convergent plate boundary?

• > <

• < >

• ^ ^

• ^ v

A plate boundary is a place where two tectonic plates meet. There are several types of tectonic plate boundaries. Which statement below shows the correct definition of a tectonic plate boundary?

• At a transform boundary, plates move apart.

• At a convergent boundary, plates slide past each other.

• At a divergent boundary, one plate sinks under another plate.

• At a divergent boundary, plates separate.

Using underwater sonar, scientists create a map of the ocean floor. Data from the middle of the Atlantic Ocean reveals a large undersea mountain range. Which type of boundary caused this mid ocean ridge?

• convergent

• divergent

• transform

• subduction

What is the main difference between the bedrock of the continental crust and the oceanic crust according to the model?

• The continental crust is less dense, while the oceanic crust is denser.

• The continental crust is denser, while the oceanic crust is less dense.

• The continental crust is made of limestone, while the oceanic crust is made of granite.

• The continental crust is made of marble, while the oceanic crust is made of basalt.

What happens when tectonic plates move apart?

• They slide past each other and get stuck.

• They move together and one goes under the other.

• They move together and both end up bending upwards.

• They move apart, creating a gap where liquid rock can emerge.
