Rapid Changes of Earth Quiz #1
Questions and Answers
- 1.
What is a sudden release of energy in the earth's crust or upper mantle, usually caused by movement along a fault plane?
- A.
A tornado.
- B.
A tsunami.
- C.
A volcanic eruption
- D.
An earthquake.
Correct Answer
D. An earthquake.Explanation
An earthquake is a sudden release of energy in the earth's crust or upper mantle, usually caused by movement along a fault plane. This movement causes vibrations, or seismic waves, that can be felt on the surface. Tornadoes are violent windstorms that form from thunderstorms and are not related to movement along a fault plane. Tsunamis are large ocean waves usually caused by underwater earthquakes, volcanic eruptions, or landslides. Volcanic eruptions occur when molten rock, ash, and gas are discharged from a volcano. Therefore, the correct answer is an earthquake.Rate this question:

The ______________________ is the point on the earth's surface vertically above the focus of an earthquake.
Correct Answer
epicenterExplanation
The term "epicenter" refers to the point on the earth's surface that is directly above the focus or hypocenter of an earthquake. It is the location where the seismic waves originating from the earthquake reach the surface and cause the most intense shaking. By determining the epicenter, scientists can better understand the earthquake's source and assess the potential damage and risks associated with it.Rate this question:

Earthquakes kill more people than volcanoes.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Earthquakes are known to cause more fatalities compared to volcanic eruptions. Earthquakes occur more frequently and can affect larger areas, leading to a higher potential for casualties. Volcanic eruptions, on the other hand, often have more localized impacts and can be better monitored and managed. While volcanic eruptions can be devastating, they generally result in fewer deaths compared to earthquakes.Rate this question:

The Richter Scale measures how much you weigh.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The Richter Scale is a scale used to measure the magnitude or energy released by an earthquake. It does not measure weight. Therefore, the statement that the Richter Scale measures how much you weigh is false.Rate this question:

What is a fault?
- A.
A crack in an egg.
- B.
A crack in the sidewalk.
- C.
A crack in the earth's crust.
- D.
A crack caused by large buildings.
Correct Answer
C. A crack in the earth's crust.Explanation
A fault refers to a crack in the earth's crust. This crack is caused by the movement of tectonic plates, resulting in earthquakes. Faults are essential in understanding the Earth's geology and plate tectonics. They provide evidence of past and ongoing tectonic activity and help scientists predict and study seismic events.Rate this question:

A ___________________ is a large ocean wave usually caused by an underwater earthquake or a volcanic explosion.
Correct Answer
tsunamiExplanation
A tsunami is a large ocean wave usually caused by an underwater earthquake or a volcanic explosion. It is a powerful and destructive natural phenomenon that can cause widespread devastation along coastal areas. Tsunamis can travel across the ocean at high speeds and can reach great heights when they approach land. Due to their immense energy and force, they can cause significant damage to infrastructure, homes, and even loss of life. Therefore, understanding and preparing for tsunamis is crucial for coastal communities to minimize the impact of these catastrophic events.Rate this question:

What is the slow, more or less continuous movement occurring on faults?
- A.
Crawl
- B.
Cuddle
- C.
Cresting
- D.
Creep
Correct Answer
D. CreepExplanation
Creep is the slow, more or less continuous movement occurring on faults. It refers to the gradual displacement of rocks along a fault line, usually at a rate that is imperceptible to humans. This movement can happen due to the accumulation of stress and strain in the Earth's crust, causing the rocks to slowly deform and shift over time. Creep is different from sudden, catastrophic movements like earthquakes, as it occurs at a much slower pace.Rate this question:

What are earthquake scientists called?
- A.
Seismologists
- B.
Volcanologist
- C.
Ecologist
- D.
Geologist
Correct Answer
A. SeismologistsExplanation
Seismologists are scientists who study earthquakes. They specialize in understanding the causes, effects, and behavior of earthquakes. They use various instruments and techniques to monitor and analyze seismic activity, including the study of seismic waves and the measurement of ground motion. Seismologists play a crucial role in predicting and assessing the risks associated with earthquakes, as well as in developing strategies to mitigate their impact on society.Rate this question:

What do scientists use to record the waves of an earthquake?
- A.
Scale
- B.
Ruler
- C.
Seismograph
- D.
Balance
Correct Answer
C. SeismographExplanation
Scientists use a seismograph to record the waves of an earthquake. A seismograph is an instrument that detects and measures the vibrations caused by seismic waves. It consists of a pendulum or a mass on a spring that moves in response to the ground motion during an earthquake. This movement is then recorded on a rotating drum or electronically, providing valuable data for studying and understanding earthquakes. A scale, ruler, or balance would not be suitable for recording earthquake waves as they are not designed for this purpose.Rate this question:

- 10.
The point in which the earthquake originates, is called the _______________________________.
Correct Answer
focus, epicenterExplanation
The epicenter is the point on the Earth's surface directly above the hypocenter, also known as the focus, where an earthquake originates. It is the location where the seismic waves radiate outward after being generated by the sudden release of energy within the Earth's crust.Rate this question:
