GEOLOGY

Detailed explanation-1: -Seismology is the study of vibrations within Earth. These vibrations are caused by various events, including earthquakes, extraterrestrial impacts, explosions, storm waves hitting the shore, and tidal effects.

Detailed explanation-2: -Evidence #4-Seismic Waves from Earthquakes But geologists use seismic (earthquake) waves to determine the depths of Earth’s layers. Earthquakes happen to create different kinds of waves when they occur and they behave differently when they interact with different layers of Earth that scientists can measure.

Detailed explanation-3: -Geologists record the seismic waves and study how they travel through Earth. Different types of seismic waves behave differently. The speed of the waves and the paths they take reveal the structure of the planet. Using data from seismic waves geologists have learned that Earth’s interior is made up of layers.

Detailed explanation-4: -Seismologists study shock, or seismic, waves as they travel through the Earth’s interior. These waves originate from natural sources like earthquakes, and from artificial sources like man-made explosions.

Detailed explanation-5: -Seismology is the study of earthquakes and seismic waves that move through and around the Earth. A seismologist is a scientist who studies earthquakes and seismic waves.
