GEOLOGY

Detailed explanation-1: -A seismic wave is a wave of acoustic energy that travels through the Earth or another planetary body. It can result from an earthquake (or generally, a quake), volcanic eruption, magma movement, a large landslide, and a large man-made explosion that produces low-frequency acoustic energy.

Detailed explanation-2: -Types of Seismic Waves The two main types of waves are body waves and surface waves. Body waves can travel through the Earth’s inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes send out seismic energy as both body and surface waves.

Detailed explanation-3: -Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. Therefore, seismic waves are caused by earthquakes. It is the energy that travels through the earth and is recorded on seismographs.

Detailed explanation-4: -S waves are called secondary waves because they always arrive after P waves at seismic recording stations. Unlike P waves, S waves can travel only through solid materials. After both P and S waves have moved through the body of Earth, they are followed by surface waves, which travel along Earth’s surface.

Detailed explanation-5: -Body Waves-Primary (P) & Secondary (S) Waves. Surface Waves-Rayleigh & Love Waves.
