Illuminate how water affects the external processes on the slope of Hong Kong. Explain how these external processes shape the slope landscape in Hong Kong. Chemical weathering involves the decomposition of rock due to the alteration of rock minerals by chemical reactions between the rocks and the water with which they come into contact. Chemical reaction causes certain minerals to change into more vulnerable ones. This weakens the internal structure of the rocks‚ and leads to decomposition. Moisture

Yesenia Terriquez Abstract The Grand Canyon is a sided mountain carved by the Colorado River. The origin of the Grand Canyon is tied down to the tectonic erosion of the Colorado Plateau. The formation of the Grand Canyon is a big mystery. What we can say‚ is that its rock layers give us clues of how tectonic erosion occurred in the Grand Canyon. Some of those rocks can be age determined‚ but some can’t. Some of the rocks that can be age determined are the igneous rocks‚ and those rocks

Abstract The NSW Government’s Sea Level Rise Policy Statement‚ Coastal Planning Guideline: Adapting to Sea Level Rise and Draft Guidelines for Preparing Coastal Zone Management Plans have endorsed the use of a ‘risk assessment approach’ to coastal zone management. The risk assessment framework is used extensively in industry and

transfer-controlled scale growth. At higher fluid velocities‚ the scale growth rate decreases with increasing fluid velocity due to the increased flow erosion effect‚ for slurry systems. This suggests the potential of particulate erosion as a scale suppression mechanism. The model predicts the existence of an optimal slurry flow velocity‚ where scaling rate and equipment erosion rate are both zero. The optimal fluid velocity value is proposed to be used as the main parameter to improve engineering design of mineral

Coastal Processes Coasts are shaped by the sea and the action of waves. Waves act in different ways‚ through the processes of erosion‚ transportation and deposition. Coasts: A coast is found where the land meets the sea. Coasts undergo change due to coastal processes and (as with rivers) there are main processes at work: Erosion Transportation Deposition Each of these processes involves the power of the sea and the effect of waves that are carried to shore. However other factors also

little water in the river giving it less energy to change the depth of the channel by erosion. As you go downstream the volume/amount of water (also known as discharge) also increases because more and more tributaries join the main river. The increase of water makes the energy levels rise when theres moe energy there is more erosion (in the form of abrasion‚ attrition and hydraulic action). these types of erosion erode away at the river bed creating a deeper channel. Whilst the depth varies downstream

As a result‚ the environment faces many critical issues‚ such as: • water shortages; • unclean water sources; • air pollution; • deforestation; • natural disasters from earthquakes‚ floods‚ and typhoons; • soil erosion from unwise agricultural methods. An ever-growing population naturally results in more pollution. As the industrial sector grows and more people drive cars‚ air pollution becomes an increasingly difficult problem to handle.

and transporting it somewhere else to deposit. There are many examples within Michigan alone of glacial movement. Drumlins‚ formed by receding and then advancing glaciers‚ scrape and pushed elongated hills together on the surface of the earth. This erosion/deposit can be seen in Iron Mountain‚ Michigan (Wilson‚ p.6). Other landforms created by glaciers are moraines‚ eskers‚ and kames. Moraines occur when the ice is melting at an equal rate of the glacier advancing‚ and so dumping rocks‚ soil‚ debris
