Soil erosion can be prevented by adding a few plants or trees where the soil typically erodes, adding fencing gullies and removing wildlife that will eat the vegetation. The eroding of the soil occurs naturally whenever there is moving water or even exposure to the wind.
When erosion occurs in waterways, it can result in an overflow of silt. Silt can damage plants and animals in streams, lakes and harbors just as easily as pollution can by covering up young plants and killing animals. Soil erosion can often be prevented if individuals and companies are more careful about the way the land is being used.Learn More
Acid rain slowly dissolves many types of stone. Calcium-based minerals such as marble and limestone are particularly vulnerable; this is due to calcium's reaction with the sulfuric acid in acid rain.Full Answer >
Mechanical weathering is the erosion of rock caused by physical processes. Extreme temperature changes and constant exposure to water or air are common causes of mechanical weathering.Full Answer >
Three main natural forces bring about erosion: wind, water and ice. When water flows and moves heavily, it can cause soil erosion. Strong winds, especially in the desert, erode sand dunes. Glacial erosion has significantly shaped the surface of the earth for millions of years.Full Answer >
The general formula for the Doppler shift is the velocity of the wave medium plus the relative velocity of the receiver, divided by the velocity of the wave medium plus the velocity of the relative source, times the emitted frequency. The Doppler shift is also called the Doppler effect.Full Answer >
