What is the water that moves across earth's surface after a heavy rainfall called?

Answer 1

Erosion is the process of Weathering and transport of solids (Sediment, Soil, Rock_(geology) and other particles) in the natural environment or their source and deposits them elsewhere. It usually occurs due to Sediment_transport by wind, water, or ice; by down-slope Downhill_creep of soil and other material under the force of Gravity; or by living organisms, such as burrowing animals, in the case of Bioerosion.

Erosion is a natural process, but it has been increased dramatically by human Land_use, especially Industrial_agriculture, Deforestation, and Urban_sprawl. Land that is used for industrial agriculture generally experiences a significantly greater rate of erosion than that of land under natural vegetation, or land used for Sustainable_agriculture practices. This is particularly true if tillage is used, which reduces vegetation cover on the surface of the soil and disturbs both soil structure and plant roots that would otherwise hold the soil in place. However, improved land use practices can limit erosion, using techniques such as Terrace_(agriculture)-building, conservation tillage practices, and tree planting.

A certain amount of erosion is natural and, in fact, healthy for the Ecosystem. For example, Gravel continuously move downstream in watercourses. Excessive erosion, however, causes serious problems, such as receiving water Sediment, ecosystem damage and outright loss of soil.

Erosion is distinguished from Weathering, which is the process of chemical or physical breakdown of the minerals in the rocks, although the two processes may occur concurrently.

THE LONG AND SHORT of what he may be trying to say is:

The water that runs across the surface is called surface run off

Answer 2

The water that moves across Earth's surface after a heavy rainfall is called runoff. Runoff can collect pollutants and sediment as it flows, potentially impacting water quality and ecosystems.
