The Earth's land surface is dominated by sloping landscapes. Every year, soil erosion laterally distributes on the order of 75 Gt of topsoil (Berhe et al. 2007). The coupled biogeochemical cycles ...

Soil erosion is a major worldwide threat to agro-ecosystem sustainability and land productivity. Fallout radionuclides and stable isotopes are used to measure magnitudes and sources of soil erosion, ...

A study of 82 sites in 21 counties by Iowa State University showed that in the 50 years from 1959, soil structure and levels of organic matter had degraded while acidity had increased. “Erosion ...

While water erosion continues to be the most serious cause of soil degradation globally, innovative strategies that remediate important soil functions can restore the productivity of eroded soils.

Weathering and erosion slowly chisel ... When the glacier begins to melt, it deposits its cargo of soil and rock, transporting the rocky debris toward the sea. Every year, rivers deposit millions ...

Erosion is the process that wears away the river ... making it heavy and liable to slide. Soil creep is a very slow movement, occurring on very gentle slopes because of the way soil particles ...

This is called differential erosion. The erosion occurs due to a number of different processes caused by the sea. Hydraulic action is when the waves smash against the coastline and the force of ...
