Faults, Earthquakes and Volcanoes Unit Test

Front

What is a strato volcano?

Back

A strato volcano, also known as a stratovolcano, is a tall, conical volcano built up of layers of lava and ash. They are known for their explosive eruptions.

Front

What is magma?

Back

Magma is molten rock located beneath the Earth's surface. When it erupts through a volcano, it is called lava.

Front

What is the San Andreas Fault?

Back

The San Andreas Fault is a major fault line located in California, known for its significant seismic activity and earthquakes.

Front

What causes tsunamis?

Back

Tsunamis are primarily caused by underwater earthquakes, volcanic eruptions, or landslides that displace large amounts of water.

Front

What is the impact of volcanic eruptions on air travel?

Back

Volcanic eruptions can disrupt air travel by releasing ash and gases into the atmosphere, which can damage aircraft engines and reduce visibility.

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

How do volcanoes create fertile soil?

Back

Volcanoes create fertile soil by depositing ash and minerals during eruptions, which enrich the soil and support agriculture.

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 lithosphere.

Front

What is the difference between magma and lava?

Back

Magma is molten rock beneath the Earth's surface, while lava is magma that has reached the surface during a volcanic eruption.

Front

What are the primary hazards associated with earthquakes?

Back

Primary hazards include ground shaking, surface rupture, and secondary hazards like tsunamis and landslides.
