Plate Tectonics and Mountain Formation

What type of stress in normally associated with convergent boundaries?

• faulting

• tension

• shear stress

• compression

At a divergent boundary, ____________ stress is the most likely to occur.

• faulting

• tension

• shear stress

• compression

Which of the following helps to explain why tectonic plates move?

• Plates move because of the gravitational force of the moon pulling on Earth's surface.

• Plates moves because the asthenosphere is slowly moving.

• Plates move because landforms cause them to move in different directions.

• Plates move because they are slowly expanding and growing larger.

A tectonic plate is defined as

• large, slow moving pieces of Earth's lithosphere.

• large, slow moving pieces of Earth's asthenosphere.

• large, slow moving pieces of Earth's mesosphere.

• large, slow moving pieces of Earth's outer core.

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.

A geologist is studying an area after an earthquake. She notices that two streams have changed course. What would most likely explain the movement of the streams?

• The stream runs across a fault in a rift zone where two plates are diverging.

• The stream runs across a hot spot far from any tectonic plate.

• The stream runs across a transform fault that was offset by the earthquake.

• The stream runs across a subduction zone where two plates are converging.
