Erosion and sedimentation: how rivers shape the landscape
In earth science, erosion is the removal of soil, rock, or dissolved material from one position on the Earth’s crust and transporting it to another through surface processes (such as water flow or wind). Erosion differs from weathering in that it does not require movement. 1st  Physical or mechanical erosion is the process of removing rock or soil as clastic sediment, as opposed to chemical erosion, which is the process of removing soil or rock material from an environment through dissolution. [three] Eroded sediment or solutes can travel thousands of kilometers or just a few millimeters.
Rainfall, river bedrock wear, coastal erosion by the sea and waves, glacial plucking, abrasion, and scour, areal flooding, wind abrasion, groundwater processes, and mass movement processes in steep environments such as landslides and debris flows are all examples of erosion agents. The rate at which these processes occur determines how easily a surface is eroded. Physical erosion is typically accelerated on steeply sloping surfaces, and rates can be affected by climatically regulated factors such as the amount of water supplied (for example, by rain), storminess, wind speed, wave fetch, or atmospheric temperature (especially for some ice-related processes). There may be feedbacks between erosion rates and the amount of eroded material already borne by a river or glacier, for example. (5)  Deposition, or the arrival and placement of eroded materials at a new site, follows the movement of eroded materials from their original location. 1st
Erosion and weathering for kids -causes and differences
Land Use Land Cover Changes (LUCC) have a direct effect on soil erosion, which is a global environmental problem. Nepal, as a mountainous region, suffers from severe soil erosion. We used remote sensing to investigate the impact of LUCC on water erosion in the Sarada, Rapti, and Thuli Bheri river basins of Nepal from 1995 to 2015. Using the Revised Universal Soil Loss Equation and the Geographical Information System, we estimated the average annual soil loss. Our findings indicate that as agricultural lands were expanded at the expense of bare lands and forests, soil erosion increased over time, with rates of 5.35, 5.47, and 6.03 t/ha/year in 1995, 2007, and 2015, respectively. Agricultural property, on the other hand, experienced the most erosion, while forests experienced the least. Agricultural lands were severely deteriorated, especially on steeper slopes, and urgent soil and water conservation measures were required. Our research shows that long-term LUCC has a significant effect on soil erosion, and the findings can be applied to other river basins across the world.

Non-infiltrated water that flows off a field causes soil erosion. It’s amazing how little farmers, extension staff, and scientists understand about soil erosion and water penetration into the soil. The 1940s saw the first images of raindrop impact on a bare soil surface, as well as information on the mechanisms of water infiltration into the soil. Many people still believe that tillage is essential to increase water infiltration and minimize runoff, despite scientific and empirical evidence to the contrary.
Soil erosion caused by water and runoff is commonly recognized as an inevitable consequence of farming on sloping soil. However, soil depletion due to erosion or runoff is not inevitable. Erosion damage on cultivated land, according to Lal (1982), is merely a symptom of land misuse in that ecological climate. In other words, immoral farming activities were hired. The cause of erosion and its negative effects is not nature (slope and rainfall intensity), but rather man’s unreasonable farming methods. The farmer can effectively control erosion, minimize runoff, and increase water infiltration on his land by using site-specific and adapted farming systems and management practices. Runoff water is lost to crops, while infiltrated water can be used efficiently by plants, which is crucial in dry climates.
Erosion due to gravity
Soil erosion decreases crop yields and may have played a part in the extinction of ancient civilizations. It’s debatable whether erosion would have the same effect on modern societies. At the European scale, we measure the relationship between crop yields and available soil water to plants, the most significant yield-determining factor influenced by erosion. We measure the potential hazard of erosion-induced productivity losses using information on the spatial distribution of erosion rates. We show that potential productivity declines in Europe as a whole will be limited and will not pose a major threat to crop production in the next century. However, there is considerable variation within Europe, and although soil erosion is unlikely to dramatically reduce productivity in northern Europe, erosion-induced productivity declines are more likely in southern Europe.
Statistics in general
The general statistics for all variables in the dataset containing the NUTS3 units of France, Germany, and Greece are summarized in Table 1. In Greece, average yields per NUTS3 unit range from 1.43 t ha1 y1 to more than 9 t ha1 y1 in northern Germany. The rate of soil erosion varies from almost none to nearly 18 t ha1 year1. The climatic gradient, like the variations in the economic climate, is important. Bakker and others have a more thorough overview of these variables (2005b).
