state‚ the mineral salts may be washed away. 6. Burning: This kills soil organisms‚ destroys the texture and structure of the soil and finally reduces plant nutrients. 7. Erosion: This helps in washing away of soil nutrients from one place to another‚ and may occur under the influence of heavy rain or wind storm. Erosion Soil is a natural body consisting of layers of primarily mineral constituents‚ which differ from the parent materials in their texture‚ structure‚ consistence‚ color‚ chemical

river’s long profile (15 MARKS) Upper - Erosion - Vertical - Weak Erosion but strong Velocity In the upper stage of the river’s long profile‚ there is mainly vertical erosion and by abrasion. Erosion occurs when there are high-energy conditions and discharge are high after heavy rain or ice melt. The rough channel from the high velocity causes turbulence and the large‚ angular bedload is dragged along the river bed‚ causing intense downwards (vertical) erosion. Mainly large particles such as boulders

“Has there been shoreline accretion or erosion within the last year?” We studied and focused on the effect of human development on various specific locations on the Galveston beach. (Figure A below) My hypothesis was that there was severe accretion because of three reasons. Increased ship and harbor activity‚ lack of storms‚ and increasing pollution due to various cities along the coast. But how does human interference actually effect the natural erosion and accretion patterns over time? Understanding

North-West China has more than 60% of China’s poor people living there. The environment and location there is suffering from many problems such as serious soil erosions and desertification of the land. One example is the Loess Plateau in the North of China which is a barren land filled with ravines and gullies everywhere. Therefore‚ I agree to a certain extent that the North-West China has been poor due to its location. As the region is nearer towards the West‚ the North-West region is arid and

Desert are created via natural ways‚ through climate changes and natural erosion‚ the wind blowing in those areas carries little or no moisture‚ bringing only fog and mist but no rains also those winds pick up and carry rock particles and those‚ will erode the ground and or the other rocks creating furthermore erosions‚ those desert’s also are the result of human activities such as deforestation‚ when humans deplete an area of the fragile eco system

this incredible rock structure was formed‚ the soundest theory relies on the environment that surrounds these rocks. The most powerful force on the Grand Canyon is erosion‚ primarily by water‚ according to The Seven Natural Wonders‚ a data base for the natural wonders of the world. The Colorado River is the culprit of this water erosion. Water has had the most impact on the Canyon because the Colorado River is always flowing. Water can have such a weighty impact because the Canyon is located in a

a Gabion Basket‚ has been erected at the southern end of the beach. This was constructed to protect the headland from further wave erosion and to ensure the pedestrian pathway stayed open for access to the headland. The wall is ____________metres long and was built in _________. * Processes affected: The main processes affected are wave refraction‚ wave erosion and coastal transportation. The waves refract around the headland and attack the sides of the headland. Because of the sea wall the

of forest there will be an imbalance which would have a negative effect on the environment. Endangered species of flora and fauna will become in danger of extinction‚ as well as climates and weather change‚ will occur. These can be in form of soil erosion‚ flooding and global warming. Deforestation which is the cutting down or destruction of forest is also the destruction of our environment for commercial purposes. Not only will we lose our valuable trees which have taken millions of years to grow
