Answer:
The seismic waves are bent, sped up, or slowed down, or even reflected when they pass through the earth's layers. ... Bending of the waves occurs at the layer's boundaries. So, scientists study the path and speed of these waves through the earth to decipher boundaries and the materials that make up the layers.
Explanation:
i looked that up so dont give me credit. also seismic waves are basically the waves that are produced from earthquakes. and not like waves in an ocean itskinda like gravity waves in a way
Spreading centers have shallow earthquakes, while trenches have deep earthquakes.
- Earthquake is a term used to describe both sudden slip on a fault, and the resulting ground shaking and radiated seismic energy caused by the slip, or by volcanic or magmatic activity, or other sudden stress changes in the earth
- simply An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
- mainly Shallow earthquakes are between 0 and 70 km deep and are mainly associated with mid-ocean ridges, with mountain ranges in the interior of the continents of Europe and Asia, and with the mountains and ocean trenches that surround the Pacific Ocean.
- The immediate cause of most shallow earthquakes is the sudden release of stress along a fault rupture (crack) in the earth's crust.
