1. Why is Mappleton threatened by coastal erosion? The plain of Holderness did not exist before the Ice Age. It was once a wide bay backed by chalk cliffs running from Flamborough Head to Hessle‚ west of the city of Hull. Today Holderness is made up of glacial tills – sands and clays deposited by ice sheets during the Ice Age (Figure 4). The tills are soft and unstable and have little resistance to erosion. The low cliffs repeatedly slump down along rotational slip planes‚ lubricated by water which

EFFECTS OF URBANIZATION IN JAMAICA Urbanization refers to the shift of population from rural areas to cities or towns according to the Encarta Encyclopaedia. In Jamaica today‚ urbanization is a constant process for persons to move from one area to the next without hesitation compared to the previous generations. Urbanization has seen a significant increase over the years because of persons pursuing a better standard of living. People move because of the economic situation of the country which

Resources are defined as a means of meeting a need‚ particularly an economic or social need‚ of the people. The term usually refers to natural resources like land‚ water‚ air. Natural resources are largely unchanged materials of the land that are valuable to people and used in variety of ways. Pakistan is rich in natural resources. It has mountains‚ plains‚ deserts‚ fertile soils‚ rivers and oceans. Natural Resources are very important for the development and prosperity of a country. The important

contribute to the devastation of nature. Overgrazing and groundwater pumping are some of the activities that damage the land. Overgrazing is one cause of soil erosion‚ in which it turns grassland into desert where soil is eroded and becomes harder for plants and trees to grow in that area which will affect the lives living there. Soil erosion is a natural process but it becomes a problem when human activity causes it to occur much faster that under natural conditions. Groundwater also contributes

The upper course of the river starts at the source of the rivers channel. The upper course of the river is shallow and has a narrow river channel due to vertical erosion caused by hydraulic action and corrosion. It also has an uneven steep river bed due its bedload as it is large boulders as they have rough edges. This then gets transported through the upper part of the river by traction. In addition some of the bedload also gets transported by suspension and little in siltation. As the river flows

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

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
