what is the difference between sheet erosion and gully erosion?

Sheet Erosion: When water flows as a sheet down a slope and as a result, the top part of the land is washed away, such an erosion is called sheet erosion. Gully Erosion: When the running water cuts through the clayey soils and makes deep channels as gullies, then such an erosion is called gully erosion.

If original soil is erodable and wind exists, soil particles move via wind (sometimes it is called dust transport) and finally are deposited at final destination regions/areas. However, water erosion occurs when rainfall or hail occurs. Along with water some soil particles (mostly finer ones) are carried away.

Burning leaves the land exposed to erosion Burning vegetation residues after slashing exposes the soil surface to direct contact with rain. Exposed soil surface erode easily with rainfall impact leaving gullies on your field. Erosion takes away the fertile topsoil of your field.

The sediment in wind causes erosion by abrasion. Sand dunes form when the wind deposits sand. Loess form when the wind deposits clay and silt. Wind erosion can be prevented by keeping the ground covered with plants.

Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.

Soil erosion is the process of the soil being carried away by mostly water or wind. Soil depletion means that the quality of the soil goes downs, like when crops take up the soil nutrients and the farmers don't fertilize the soil to replenish the nutrients.

Weathering and erosion on the surface is dominated by rainfall and runoff. Mechanical weathering via freeze/thaw is also more pronounced on the surface. Underground erosion occurs chemically or mechanically (just as with surface erosion):

Weathering refers to the actual breaking part of the rock or soil. ... Erosion is the actual movement of the weathered material, ie when sediment flows down a river or sand is swept away by wind. Deposition happens when the weathered and eroded material is deposited and finally comes to a stand still.

Erosion is the process by which natural forces move weathered rock and soil from one place to another. ... Deposition occurs when the agents (wind or water) of erosion lay down sediment. Deposition changes the shape of the land. Erosion, weathering, and deposition are at work everywhere on Earth.

As nouns the difference between silt and loess is that silt is mud or fine earth deposited from running or standing water while loess is (geology) any sediment, dominated by silt, of eolian (wind-blown) origin.

Answer: 1) weathering is the process of something wearing away and breaking into smaller pieces, erosion is where things like water, wind, ice and gravity wear away rocks and soil and moves it from one location to another.

A sill is a concordant intrusive sheet, meaning that a sill does not cut across preexisting rock beds. ... In contrast, a dike is a discordant intrusive sheet, which does cut across older rocks. Sills are fed by dikes, except in unusual locations where they form in nearly vertical beds attached directly to a magma source.

Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Activities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion.

EROSION: Wearing away the soil and rocks. This puts lots of sand, mud, pebbles and silt into the river. TRANSPORT: Moving material. The force of the flowing water moves the mud, sand, pebbles and silt created by erosion.

Erosion is the process by which soil and rock are removed from the Earth's surface by exogenetic processes such as wind or water flow, and then transported and deposited in other locations. ... Leaching is the removal of soluble material from soil or other material by percolating water.

Similarities. Both weathering and erosion are processes that wear away rocks. These two processes collaborate to break down rocks by removing or forcing out particles and sediment. Water is a force that helps both processes to occur.

Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.
