Earthquake and Volcano Unit Test

Front

What is a hot spot?

Back

A hot spot is a location on the Earth's surface that has experienced active volcanism for a long period of time, often found in the middle of tectonic plates, away from plate boundaries.

Front

What is the significance of Hawaii in relation to hot spots?

Back

Hawaii is an example of an island chain formed by a hot spot, where the Pacific Plate moves over a stationary plume of molten rock.

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth's crust, generated by the sudden movement of the crust during an earthquake.

Front

What is lava?

Back

Lava is molten rock that reaches the Earth's surface during a volcanic eruption.

Front

What is the difference between magma and lava?

Back

Magma is molten rock located beneath the Earth's surface, while lava is magma that has erupted onto the surface.

Front

What is a caldera?

Back

A caldera is a large depression formed when a volcano erupts and collapses, often resulting in a large, basin-like structure.

Front

What is a stratovolcano?

Back

A stratovolcano is a type of volcano characterized by its steep, conical shape and is built up by layers of lava and ash.

Front

What is a shield volcano?

Back

A shield volcano is a broad, gently sloping volcano formed by the eruption of low-viscosity lava that can flow over great distances.

Front

What is an earthquake?

Back

An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's crust.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other, causing geological activity such as earthquakes and volcanic eruptions.
