EFFECTS OF SOIL EROSION IN THE PHILIPPINES
Soil erosion is happening everywhere in this world. Especially near the water area and maybe it is happening below where we stand. One my grandparents told me, that one time when they were young a typhoon with its devastating rain hit manila. Because they were near river, because of the heavy rain without warning the soil beneath their home collapse and their home was wash away in the river. And it said to be the cause of the collapse of the soil was the soil erosion. And because of soil erosion it has many effects in our self and in our country the Philippines. But first we need to know what soil erosion is, and how soil erosion works. Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow, and then transported and deposited in other locations. Soil erosion is a natural process that we cannot stop. And there is many factors that can affect on its physical process and how soil erosion work. First the Rainfall that can cause soil erosion. There are three primary types of erosion that occur as a direct result of rainfall sheet erosion, rill erosion, and gully erosion. Sheet erosion is generally seen as the first and least severe stage in the soil erosion process, which is followed by rill erosion, and finally gully erosion. It works when The impact of a falling raindrop creates a small crater in the soil, ejecting soil particles. The distance these soil particles travel (on level ground) can be as much as 2 feet vertically, and 5 feet horizontally. Once the rate of rain fall is faster than the rate of infiltration into the soil, surface runoff occurs and carries the loosened soil particles down slope. Sheet erosion is the transport of loosened soil particles by surface runoff that is flowing downhill in thin sheets. Second are those near to Rivers and streams. Valley or stream erosion occurs with continued water flow along a linear...
