Name: Lee An Qi Class: 3H/7 Date: 2 June 2012 Urbanization is the process that leads to an increase in the number and proportion of people living in urban settlements such as cities or towns. It also refers to the increase in the size of land area occupied by urban settlements. To cope with urbanization within a drainage basin‚ urban development and deforestation are carried out‚ which affect flows to and within a river channel. Other factors like drainage density‚ climate‚ area of drainage

Charmaine Farrah Estacio Geography 1 Dr. Thomas Orf 11th November 2014 ASSIGNMENT: CHAPTER 15 PRELIMINARIES TO EROSION: WEATHERING AND MASS WASTING KEY TERMS AND CONCEPTS: 1. What is meant by denudation? The total effect of all actions (weathering‚ mass wasting‚ and erosion) that lower the surface of the continents. 2. Distinguish among weathering‚ mass wasting‚ and erosion. Weathering- The physical and chemical disintegration of rock that is exposed to the atmosphere. Mass Wasting- The short-distance

Plant trees: We all know that the roots of trees firmly hold on to the soil. As trees grow tall‚ they also keep rooting deeper into the soil. As the roots of the trees spread deep into the layers of soil‚ they contribute to the prevention of soil erosion. Soil that is under a vegetative cover has hardly any chance of getting eroded as the vegetative cover acts as a wind barrier as well. Terraces: Terracing is one of the very good methods of soil conservation. A terrace is a leveled section of a

Section A - Restless Earth The earth’s structure At the centre of the earth is the core. Surrounding that is a mass of molten rock called the mantle. The thin layer on the outside is called the crust. There are two types of crust‚ continental and oceanic. The crust is made up of seven major plates and many smaller ones. The plates move due to convection currents rising in the mantle. Distribution of earthquakes and volcanoes Mainly found along plate boundaries. In

Haiti faces current environment issues‚ such as extensive deforestation‚ soil erosion‚ and inadequate supply of portable water. Their drinking water source has improved in the urban‚ and rural areas to a percentage of 69. In the urban and rural areas the drinking water source has unimproved to a percentage of 31 in 2010.

The waves spill over. They are constructive. * The process by which the direction of a wave is changed when it moves in to shallower water. * The energy of water impacting on a cracks and joint. Air is compressed into the space‚ leading to erosion. * When particles of sand or rock further abrade the rock surface. * When the waves wear away at the base of a cliff‚ often forming a notch. * The wearing a way of rocks after they have been removed from the cliff face. * The distance

causes of landslides include: • groundwater (pore water) pressure acting to destabilize the slope • Loss or absence of vertical vegetative structure‚ soil nutrients‚ and soil structure (e.g. fire in forests etc.lasting for 3-4 days) • erosion of the toe of a slope by rivers or ocean waves • weakening of a slope through saturation by snow melt‚ glaciers melting‚ or heavy rains • earthquakes adding loads to barely stable slope • earthquake-caused liquefaction destabilizing slopes

mucus from the epithelial cells of human’s trachea. In serious conditions‚ death might occur due to suffocation of asthma patients. This will increase the death rate in the country. Another consequence of open burning is that it may lead to soil erosion. Due to weak grip of tree roots‚ soil will eventually wash off during rain. Then the top layer of the soil will erode and wash off from the land into the lower region‚ normally the river. In a long run‚ soil will reduce the depth of river water
