regions of the Himalayan foothills ultimately leads to major erosion of the land. When trees are cut off‚ the land becomes bare and unprotected. This makes the earth vulnerable towards wind‚ water‚ or glaciers to erode the soil and earth. Another way of deforesting the land is by the use of fire. When people burn down forests‚ the fire may be uncontrollable‚ and it will destroy even more natural vegetation. This also encourages erosion of the land‚ because there is no vegetation cover to protect

mentioned above. Its current height is now stated at 3‚753 meters making it the tallest mountain in Australasia. The mountain itself has been formed by three main geological processes; one internal: tectonic uplifting and 2 external: weathering and erosion. Internal: 1. Tectonic Uplifting Mt. Cook was formed by the internal process of orgenic tectonic uplifting‚ where two plates collide and one plate increases in elevation and the opposite plate decreases. However Mt. Cook formed differently

One of the causes of land degradation includes water erosion‚ the most widespread type of land degradation affecting Australia. impact of this issue - how does this issue impact on the environment Water erosion involves the removal of soil particles by water erosion‚ losing great amounts of soil where the vegetation cover is thinnest. Plant roods bind the soil‚ while leaves protect it from the impact of heavy

nourishment. Beach nourishment is a common method used by many countries‚ including Singapore and the United States‚ among other influential countries. Its main objective is to import sediment and replenish materials lost through longshore drift and erosion from destructive waves‚ and is one of the more popular soft coastal management systems worldwide. This is usually done on a large scale‚ and extends the beach seawards‚ usually by close to a kilometre‚ depending on the local environment or necessity

Causes Consequences Solutions Soil Erosion Water‚ wind‚ and people. (Miller‚2005 p.279) ●Soil erosion has two major harmful effects. One is loss of soil fertility through depletion of plant nutrients in topsoil. The other harmful effect occurs when eroded soil ends up as sediment in nearby surface waters‚ where it can pollute

with erosion‚ however‚ every method comes with disadvantages. One way in which soft engineering working well with the natural environment and is also effective‚ is beach nourishment. This is where materials such as sand and shingle are moved from the bed out at sea or further down the coast and placed at the location of the eroding beach‚ this therefore creates a wider beach. Wider beaches absorb the energy of the waves before they can create damage to the coast‚ as they reduce the erosion of the

In the lower course of the river valley‚ lateral erosion is denominate. This makes the valleys much wider than the upper course.
