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

and Concepts (1-24) 1. Denudation is the total effect of all actions (weathering‚ mass wasting‚ and erosion) that lower the surface of the continents. 2. Weathering- the physical and chemical disintegration of rock that is exposed to the atmosphere. Mass-wasting- the short-distance down slope movement of weathered rock under the direct influence of gravity; also called mass movement. Erosion- detachment‚ removal‚ and transportation of fragmented rock material. 3. Openings in the surface and

Soil degradation refers to the decline in quantity and quality of soil. Degradation of soil is done by erosion (wind and water)‚ biological degradation‚ physical degradation (referring to the over loss of structure and changes in permeability) and chemical degradation‚ this refers to acidification‚ declining fertility‚ changes in pH levels‚ salinization and chemical toxicity. Soil degradation affects not only the environment but also the economy as well as people. The effect that soil degradation

Illuminate how water affects the external processes on the slope of Hong Kong. Explain how these external processes shape the slope landscape in Hong Kong. Chemical weathering involves the decomposition of rock due to the alteration of rock minerals by chemical reactions between the rocks and the water with which they come into contact. Chemical reaction causes certain minerals to change into more vulnerable ones. This weakens the internal structure of the rocks‚ and leads to decomposition. Moisture

In the Puget Sound landslides are fairly common‚ mostly due to a very wet climate and ever changing environment. The definition of a landslide is: A gravity driven down slope movement of a mass composed of soil‚ rock‚ and vegetation. A landslide generally happens when the material in the down slope is heavier then the supporting soil. There are many contributing factors that cause landslides‚ steepness of slope‚ composition of soil and rock‚ groundwater condition‚ recent precipitation patterns

Poverty is general scarcity or dearth‚ or the state of one who lacks a certain amount of material possessions or money.[1] Absolute poverty or destitution refers to the deprivation of basic human needs‚ which commonly includes food‚ water‚ sanitation‚ clothing‚ shelter‚ health care and education. Relative poverty is defined contextually as economic inequality in the location or society in which people live.[2][3]After the industrial revolution‚ mass production in factories made production goods increasingly

Soil conservation includes all such measures which protect the soil from erosion and restore its fertility. These measures are of two types-(a) small measures to check soil erosion at local or even individual level‚ and (b) large measures at government level involving larger area and heavy investment. (a) Small Measures-These include afforestation‚ regularised land strip cultivation or contour farming or terrace farming in hilly areas‚ use of stubble mulch system‚ increasing cohesiveness of the

of a river is the speed at which water flows along it. Lateral erosion- Lateral erosion in a river is the wearing away of the sides of the river which makes the channel deeper because rocks being carried in the river will erode the sides of a river. Bed load - Bed load is complementary to suspended load and wash load. Bed load moves by rolling‚ sliding‚ and saltating. Vertical erosion- Vertical erosion is the downward erosion which deepens the river channel. Hypothesis Whedn going

CCEA GCSE‚ K. Clarke Pg.2) Rivers as agents of change in the landscape (TED depending on available energy) “Rivers change the landscape through which they flow. They alter it by erosion‚ transportation and depostition” (http://www.bbc.co.uk/schools/riversandcoasts/rivers/change_river/pg_06.shtml 18.06.2013) River erosion is the wearing away of the land as the water flows past the bed and banks. River deposition happens whenever the velocity of the river drops; meaning that there isn’t enough energy
