Answer:
Neither
Explanation:
None of the answer choices is the correct definition of erosion. Erosion is actually the removal of weathered materials and particle from the surface of rocks and soils.
- The process by which rocks and soils are moved is called transportation.
- The process of disintegration of rocks and soil is called weathering.
Erosion is a serious problem in Agriculture as it removes rich and fertile soil cover. This therefore renders the soil barren and stripped of available nutrients.
I believe the correct answer is no, it is impossible to have 5.0*10^-25g of Al. One atom of Al weighs <span>4.48*10^-23 g/atom Al which means</span> it is impossible to have any weight of Al less than that. Hope this answers the question. Have a nice day.
The can lead to mass wasting
Explanation:
Weathering and erosion can be a bad thing because they can lead or trigger mass wasting.
- Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
- Erosion is the washing away of weathered materials.
- Mass-wasting is the movement of materials down-slope under gravity.
- Both weathering and erosion can lead to serious problems like mass-wasting because they are earth moving processes.
- Weathering can lead to the formation of sinkholes in an area where rocks are decomposed chemically.
- Erosion can wash away top fertile layer of soil and makes them bare. This can lead to drought.
- Rock fall can be initiated when rocks physically disintegrate.
- Chemical weathering can lead to rust and destruction of structures.
- Undercutting of structures by erosion can lead to the collapse of bridges.
