GENERAL 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 waves of energy that are transported through the earth and over its surface by means of both transverse and longitudinal waves.

Detailed explanation-4: -Seismic waves travel a curving path through the earth due to changes in composition, pressure, and temperature within the layers of the Earth. Seismic waves travel at different speeds through different materials. In this 2-layer model two wave fronts leave an impact at the same time but the lower layer is faster.

Detailed explanation-5: -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.
