Coastal Erosion Coastal erosion is a naturally occurring phenomenon resulting from the continuous action of wind and water. Both act to remove small pieces of land from one location and deposit them elsewhere. Weather events such as hurricanes and nor’easters speed the erosion process‚ as do tidal waves. Currently‚ rising sea levels resulting from melting polar ice decrease available land as well. While erosion has always been a factor of coastal living‚ increasing populations along the worlds

SOilIntroduction Soil plays a vital role in our ability to cultivate crops. Throughout human history‚ our relationship with the soil has affected our ability to cultivate crops and influenced the success of civilizations. This relationship between humans‚ the earth‚ and food sources affirms soil as the foundation of agriculture. Soil testing is necessary for knowledge of characteristic of the soil‚ quantity of fertilizer is needed so that fertilizers are used only as needed‚ not too less or too

the buildings reduce the beaches ad many construction sites extract coastal sand for their projects. The coastal erosion that affects my hotel are both natural and anthropogenic. The slow rise of the sea level is gradual and takes time to happen‚ but this region is impacted by hurricanes and tropical storms which cause a severe costal erosion in short time. Many efforts to combat erosion‚ such as sand fill‚ are defeated by severe weather systems. As we have seen on all natural processes‚ there is balance

Soil Porosity and Permeability GEO 101 LAB – Earth Science July 26‚ 2014 Soil Porosity and Permeability The focus of week three’s lab in Earth Science is to figure out the porosity and permeability of four different soil types: gravel‚ sand‚ potting soil‚ and soil from my back yard. This lab is designed to look at the porosity and permeability of these four soil samples. Porosity is basically the measure of how much of the soil volume is open space. Permeability is the measurement of how long

Landforms by Erosion (erosion is the main process) * High-energy waves * Rocks that are easily eroded 1) Cliff and shore platforms Point : A cliff is a high‚ steep rock face along the coast. Explanation: A cliff is formed when waves repeatedly pound against a rocky coast Elaboration: This weakens the rock‚ causing the lines of weakness to form in the rock face * Over time‚ the waves erode the coast to cut a notch along the lines of weakness. * The notch may be further

Coastal Erosion Coastal Erosion is a huge problem today and is causing our beaches to get smaller and smaller every year. Coastal erosion is also causing the coast lines to recede and therefore taking away space for which people build on. Even though coastal erosion causes issues it is also the effect of something‚ Humans! Nature has a way of keeping the world in balance‚ it creates things such as barrier islands and sand dunes to help protect against costal erosion. However‚ humans play a

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
