1.what are seismic waves? 2.how will you describe a figure A? 3.how will you describe figure B? 4.how is an earthquake generated? 5.How do seismic waves behave as they travel deeper down the earth?
1.Seismic waves are waves of energy that travel through Earth's layers, and are a result of earthquakes, volcanic eruptions, magma movement, large landslides and large man-made explosions that give out low-frequency acoustic energy.
2.The S wave shadow zone is the area of the Earth's surface where S waves are not detected following an earthquake. This shadow zone has led geologists to a model of the Earth with a solid mantle and a liquid core. From the diagram, we can see the region where S waves are not detected.
3.The shadow zone is the area of the earth from angular distances of 104 to 140 degrees from a given earthquake that does not receive any direct P waves. The shadow zone results from S waves being stopped entirely by the liquid core and P waves being bent (refracted) by the liquid core.
4.An earthquake is caused by a sudden slip on a fault. ... When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. In California there are two plates - the Pacific Plate and the North American Plate.
5.Seismic waves travel more quickly through denser materials and therefore generally travel more quickly with depth. ... Seismic waves move more slowly through a liquid than a solid. Molten areas within the Earth slow down P waves and stop S waves because their shearing motion cannot be transmitted through a liquid.

hope it helps I purple you everyone. Study well and trust me its correct.
