5.crust

Answer 2

Answer:

1. The instrument used to measure the intensity of an earthquake. Seismometer.

2. Huge waves caused by the undersea earthquake. Tsunami

3. Volcanoes that have stopped erupting. Dormant volcano

4. A person who studies an earthquake. Seismologists

5. The layer of the earth in which an earthquake occurs. Crust

Explanation:

1) A seismometer is an instrument that responds to ground motions, such as earthquakes, volcanic eruptions, and explosions. Seismometers are usually combined with a timing device and a recording device to form a seismograph.

2) A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions, and other underwater explosions above or below water all have the potential to generate a tsunami

3) A dormant volcano is an active volcano that is not erupting, but supposed to erupt again. An extinct volcano has not had an eruption for at least 10,000 years and is not expected to erupt again in a comparable time scale of the future.

4) Seismology is the scientific study of earthquakes and the propagation of elastic waves through the Earth or other planet-like bodies.

5) “Crust” describes the outermost shell of a terrestrial planet.
