Answer:
A. S shock waves fade out as they travel through the earth.
Explanation:
Seismic waves lose a great number of their energy when they travel over long distances so after an earthquake, they are not recorded on the seismograph.
S waves don't get recorded on seismographs all over the globe after an earthquake because they fade out as they travel through the earth.

Answer:
As it is a cold current, except at times of the phenomenon known as El Niño (q.v.), the Peru Current brings fog to the nearby coast but also helps to keep the coast one of the most intensely arid areas in the world. The cold flow is intensified by upwelling of deep water caused by the combined effects of the drag of surface winds of the Southeast Trades and the Earth’s rotation. Upwelling brings abundant nutrients close to the surface, and the beneficial effects of sunlight, which allow for rich plankton growth, make the waters off Peru, Chile, and Ecuador one of the world’s greatest fishing grounds for anchovies and the larger fish (e.g., tuna) that feed upon them. Another economic benefit is the guano, used for fertilizer, deposited by the flocks of birds that feed on the anchovies.
The current’s alternative name is taken from that of the German scientist Alexander von Humboldt, who in 1802 took measurements that showed the coldness of the flow in relation to the air above it and the sea around it.
Soil erosion removes the top soil that is the most valuable part of the soil for agricultural purposes. With this loss of important soil, there is lower yield but higher cost of cultivation.
Soil erosion will work its way downstream that will find its way into the water systems of cities. The top soil may contain pesticides and fertilizers. The soil will also find its way into streams and rivers where it could possibly clog up the natural channels of waterflow.
