Effects of Drought Natural phenomenon along with being very beautiful and useful for humankind‚ sometimes become very disastrous and demolishing for them. They show a negative side of nature and indicate some very demolishing aspects of nature‚ which the humans cannot ignore because of possessing less power. These incidents remind people that they do not have the control over everything and they are very small in front of such natural calamities. However‚ with strategic and wise planning one can

river basin‚ e.g. Nepal‚ Bhutan and Northern India. This is a result of population growth (more wood is needed for cooking and heating. Also more forests are cleared for farm land). This has led to increased flooding. This is a result of: * More erosion of soil as roots no longer hold soil together * Less take-up of water by plant roots * Less interception of rain fall by vegetation cover Positive impact of flooding in Ganges/Brahmaputra river basin Regular annual flooding is essential

problems are too profound that beyond the capbility of individuals to solve. Firstly‚ the lack of professional knowledge as well as time and fund for investigation make it impossible for individuals to deal with problems such as sand storm‚ soil erosion and salinity. Secondly‚ laws must be made to regulate industrial enterprises and any misconduct causes pollution will lead to serious punishments. This can only be implemented by the government while the individual’s strength seems to be minor at

Mass Movements and Their Human Impacts Mass Movement is defined as the down slope movement of rock and regolith near the Earth’s surface mainly due to the force of gravity. Mass movements are an important part of the erosional process‚ as it moves material from higher elevations to lower elevations where transporting agents like streams and glaciers can then pick up the material and move it to even lower elevations. Mass movement processes are occurring continuously on all slopes; some act very

The Oregon Coast Range is composed of accreted oceanic sediments. The oldest rocks were formed during the Paleocene to the middle of the Eocene era. The rocks are gently folded and have a slight westward dip. As we walked out onto the Jetty‚ you could see how the waves came in at a slight angle rather than directly at the coast. Most of the rocks (particularly the smaller hand held size rocks) were jagged and triangular looking. This told me that these rocks came from a relatively close proximity

and many other useful articles.They keep our environment clean and fresh.They use up the carbon dioxide during photosynthesis and give out oxygen.They give us shade throughout the year‚and attract rain clouds.The roots of trees also prevent soil erosion. Forests are very important in preserving the balance of the eco-system. They provide sanctuary to wild animals.Unfortunately‚man has been indiscriminately cutting down forests.This has resulted in a considerable decrease in rainfall in some places

Every year about 30 million people and 10 million hectares are affected and the property lost may run into thousands of corers of rupees. The annual loss of top soil is estimated 6000 million tonnes; its value in terms of money is enormous. Soil erosion also causes siltation of lakes and rivers. Felling of trees and destruction of forests cause imbalance in forests ecosystem. That reflects in the loss of varieties of flora and fauna. Forest loss is a threat to wildlife survival.

External Forces One and Two Weathering- is the process that changes solid rocks into sediments. There are four types of weathering water‚ wind‚ glaciers‚ and gravity Water is responsible for most weathering Wind moves sand-sized particles of rock through the air Glaciers move all sizes of sediment Gravity moves broken pieces of rock downslope Physical Weathering- involves the breaking down of rocks into situ without any change in the composition Freeze Thaw- when water seeps into the cracks and
