Faults, Earthquakes and Volcanoes Unit Test

What is a volcanic eruption?

• A sudden release of water from a lake

• The release of magma, gas, and ash from a volcano, which can vary in intensity and impact.

• A type of earthquake caused by tectonic plate movement

• A natural phenomenon that occurs only in tropical regions.

What are the benefits of studying earthquakes and volcanoes?

• It helps us understand natural hazards, improve safety measures, and predict future events.

• It allows us to create more powerful earthquakes and volcanoes.

• It provides a way to control the weather patterns.

• It helps in the development of new technologies unrelated to natural disasters.

What is magma?

• Molten rock located beneath the Earth's surface.

• A type of gas found in the atmosphere.

• Solid rock found in the Earth's crust.

• A liquid found in oceans and rivers.

What role do tectonic plates play in earthquakes?

• Tectonic plates are large sections of the Earth's crust that move and interact at their boundaries, causing earthquakes when they grind against each other.

• Tectonic plates are small fragments of the Earth's surface that float on the ocean and cause tsunamis.

• Tectonic plates are layers of the atmosphere that influence weather patterns and climate change.

• Tectonic plates are solid rocks that remain stationary and do not affect seismic activity.

What is a strato volcano?

• A type of volcano that is flat and wide.

• A tall, conical volcano built up of layers of lava and ash.

• A volcano that erupts only lava flows.

• A small, dome-shaped volcano that erupts gently.

How do volcanoes create fertile soil?

• By depositing ash and minerals during eruptions, which enrich the soil and support agriculture.

• By releasing gases that promote plant growth.

• By creating new land that is naturally fertile.

• By cooling lava that forms rich organic matter.

What is the impact of volcanic eruptions on air travel?

• Volcanic eruptions can improve air travel by clearing the atmosphere of pollutants.

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

• Volcanic eruptions have no significant impact on air travel.

• Volcanic eruptions can lead to increased flight speeds due to changes in atmospheric pressure.

What is the Ring of Fire?

• A region in the Atlantic Ocean known for its calm waters.

• A horseshoe-shaped area in the Pacific Ocean basin known for its high volcanic and earthquake activity.

• A mountain range in Europe famous for its skiing resorts.

• A desert area in Africa with minimal geological activity.

What is an earthquake?

• A volcanic eruption that causes ground shaking.

• The shaking of the Earth's surface caused by the sudden release of energy in the Earth's lithosphere.

• A weather phenomenon that results in strong winds.

• A type of seismic wave that travels through the Earth's crust.

What is the San Andreas Fault?

• A major fault line located in California, known for its significant seismic activity and earthquakes.

• A river that runs through California.

• A mountain range in California.

• A historical landmark in California.
