what are seismic waves? Explain the phenomenon of production of seismic waves
Answers
Answer:
the propagation velocity of siesmic waves depends on density and elasticity of the medium as well as the type of wave. velocity tends to increase with depth through earth's crust and mantle, but drops sharply going from the mantle to the outer core
Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion.
Explanation:
The energy waves moving through Earth's rocks, resulting from earthquakes, volcanic eruptions, magma movement, large landslides, and massive human-made acoustic explosions are called Seismic waves. Many other natural and anthropogenic sources produce waves of low amplitude usually called ambient vibrations. Geophysicists, or seismologists, research the seismic waves.
A seismometer, hydrophone (in water), or accelerometer is used to measure seismic wave fields. Seismic waves are simply mechanical intermittent waves (machine vibrating produces identical continuous waves). Their mechanical or physical motion creates them. They can be artificially generated as a guided source for use in exploration.
