Estimates presented here are based upon the latest information from the National Resources Inventory (NRI). The NRI is a longitudinal sample survey based upon scientific statistical principles and procedures. Soil erosion affects soil health and productivity by removing the highly fertile topsoil and exposing the remaining soil.. Soil erosion decreases agricultural productivity, degrades ecosystem functions, amplifies hydrogeological risk such as landslides or floods, causes significant losses in biodiversity, damage to urban infrastructure and, in severe cases, leads to displacement of human visit http://www.makemegenius.com for more free science videos for kids.Soil is one of the most important natural resources on earth.

Soil erosion

While soil erosion is a naturally occurring process Soil erosion is one of the most serious environmental and public health problems facing human society. Humans obtain more than 99.7% of their food (calories) from the land and less than 0.3% from the oceans and other aquatic ecosystems. Each year about 10 million ha of cropland are lost due to soil When relating to soil, erosion refers to the wearing away of the top layer of soil. Naturally, this may occur by wind, water, snow or ice as with all types of erosion.

An Assessment of the global impact of 21st century land use change on soil erosionHuman activity and related land use change are the primary cause of accelerated soil erosion, which has substantial implications for nutrient and carbon cycling, land productivity and in turn, worldwide socio-economic conditions. In earth science, erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location. Erosion is distinct from weathering which involves no movement.
