The difference between erosion and weathering is that erosion involves movement while weathering takes place without movement. Both processes are involved in the decomposition of rocks.
There are two kinds of weathering, mechanical and chemical. Mechanical weathering breaks rocks into small pieces and fragments. Chemical weathering changes mineral structures inside of rocks. The pieces of rock fall off, but the rock itself stays put during both types of weathering processes. Erosion, which is also called mass wasting, happens when the weathered pieces of rock roll down-slope, along with another agent, such as in the case of a mud slide or moving ice floe.Learn More
Poor agricultural practices, deforestation and the overgrazing of livestock are some of the causes of soil nutrient depletion. These activities ultimately lead to soil erosion, waterlogging, salinization and desertification, which is when soil loses 10 percent of its productivity.Full Answer >
Urban decay can fragment families, cause loss of jobs, result in depopulation, promote crime, lead to loss of political privileges and contribute to deindustrialization, reports Boundless. Poverty is the main cause of urban decay. A city that falls into urban decay may recover from its social economic challenges or require rebuilding. Changes in government policies on economic activities and failure of communication and transport infrastructure contribute to urban decay.Full Answer >
Weathering, which is the process by which rocks and minerals are broken down, causes deterioration of otherwise strong materials. Weathering is caused by water, ice, temperature changes, salt, chemical processes, plants and animals.Full Answer >
Gravity is the driving force behind all agents of erosion. The process of erosion moves rock, soil and minerals from one location to another because of wind, running water, waves, glaciers and rain. Gravity forces rocks and soil downward from hilltops and mountains, thereby eroding the surface of the Earth. Precipitation falls to the Earth due to gravity, causing erosion from the water cycle.Full Answer >
