Rainwater also mixes with chemicals as it falls from the sky, forming an acidic concoction that dissolves rock. Back up on the mountains, snow and ice build up into glaciers that weigh on the rocks beneath and slowly push them downhill under the force of gravity.
Together with advancing ice, the rocks carve out a path as the glacier slumps down the mountain. 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 of tons of sediment into the oceans. Without the erosive forces of water, wind, and ice, rock debris would simply pile up where it forms and obscure from view nature's weathered sculptures. Although erosion is a natural process, abusive land-use practices such as deforestation and overgrazing can expedite erosion and strip the land of soils needed for food to grow.

The quality of water flowing from the land into the reef lagoon has deteriorated over the past years. Major floods deliver large levels of pollutants including eroded soil from river catchments onto the reef. These soils are especially vulnerable to most forms of soil erosion and can affect infrastructure projects such as:.
Home Environment, land and water Land, housing and property Land and vegetation management Soil management Erosion Impacts of erosion. Print Impacts of erosion All soils can suffer erosion but some are more vulnerable than others. Agriculture Soil erosion removes valuable top soil which is the most productive part of the soil profile for agricultural purposes. The impacts of erosion on cropping lands include: reduced ability of the soil to store water and nutrients exposure of subsoil , which often has poor physical and chemical properties higher rates of runoff, shedding water and nutrients otherwise used for crop growth loss of newly planted crops deposits of silt in low-lying areas.
