Volcanoes, Earthquake, and Mountain Ranges

What causes most volcanoes at convergent plate boundaries?

• Melting of crust due to sunlight

• Subduction of one plate beneath another

• Faulting due to erosion

• Movement of ocean currents

These volcanoes have a broad, gently sloping cone shape, similar to a warrior's shield laid on the ground

• Lava domes
• Stratovolcanoes
• Cinder cone volcanoes
• Shield volcanoes

They are usually formed by explosive eruptions that eject the material from a single vent, piling it up around the vent.

• Shield volcano
• Cinder cone volcano
• Stratovolcano
• Lava dome

What is the term called for the molten rocks on the surface of a volcano?

• ash
• magma
• tephra
• lava

What do we call the opening through which things come out of a volcano?

• magma chamber
• crater
• caldera
• vent

Earthquakes are most often caused by:

• Tidal forces

• Movement of tectonic plates

• Changes in climate

• Volcanic ash deposits

The release of built-up stress from plate movement along a fault produces:

• A tsunami

• A landslide

• An earthquake

• A volcanic eruption

What causes the crust to fold and create mountain ranges at some plate boundaries?

• Rising sea levels

• Subduction of magma

• Colliding continental plates

• Movement along transform faults

Which process explains how new mountains and volcanoes continue to form today?

• Ice melting

• Wind erosion

• Sediment compaction

• Ongoing plate movement

Which of the following describes a body seismic wave?

• Body seismic waves are waves that travel through the Earth's interior.
• Body seismic waves only travel along the Earth's surface.
• Body seismic waves are caused by volcanic eruptions.
• Body seismic waves are only detected by surface instruments.
