Earthquakes: Quiz 1

Magnitude

• The amount of energy released from an Earthquake

• The depth of the earthquake's focus

• The distance from the epicenter

• The duration of the earthquake's shaking

Intensity

• Describes the amount of damage done by an Earthquake

• Measures the depth of an Earthquake

• Indicates the frequency of Earthquake occurrences

• Assesses the duration of an Earthquake's shaking

Richter Scale

• A scale used to measure the temperature of an earthquake.

• A scale used to measure the magnitude of an earthquake. This is the number you usually hear on the news.

• A scale used to measure the depth of an earthquake.

• A scale used to measure the duration of an earthquake.

Mercalli Scale

• Scale used to rate earthquakes based on the amount of damage done

• Scale used to measure the magnitude of earthquakes

• Scale used to predict future earthquakes

• Scale used to classify types of seismic waves

Faults

• Cracks in the Earth's crust where most earthquakes occur

• Areas of high pressure that cause volcanic eruptions

• Regions where tectonic plates are stable and do not move

• Locations where the Earth's crust is thicker than average

Mantle

• The outermost layer of the Earth.

• The middle layer of the Earth. This is where convection currents occur.

• The layer of the Earth that contains the tectonic plates.

• The innermost layer of the Earth, composed mainly of iron and nickel.

Seismologist

• A scientist that studies earthquakes

• A scientist that studies weather patterns

• A scientist that studies animal behavior

• A scientist that studies human anatomy

Earthquake

• The shaking of Earth's crust caused by a release in energy

• A sudden increase in temperature in the atmosphere

• A large body of water that is surrounded by land

• A geological formation caused by volcanic activity

Aftershock

• A smaller earthquake that follows the main shock and occurs in the same area

• A large earthquake that occurs before the main shock

• An earthquake that occurs at a different location than the main shock

• A minor tremor that has no significant impact

Crust

• The outermost layer of the Earth

• The innermost layer of the Earth

• A type of rock found in the Earth's mantle

• A layer of gases surrounding the Earth
