Detailed explanation-1: -Body waves are those waves that travel through the earth. They originate at the epicentre of the earthquake and travel through the earth at amazing speeds. There are two types of body waves, namely, P waves.
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 that travel through or over Earth. They are usually generated by movements of the Earth’s tectonic plates (earthquakes) but may also be caused by explosions, volcanoes and landslides.
Detailed explanation-4: -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-5: -There are three major kinds of seismic waves: P, S, and surface waves. P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface.
