Question

What is soil erosion ? Explain the different ways in which soil is eroded.
Discuss the various methods being used to conserve soi

Answer 1

Answer:

Soil erosion is the displacement of the upper layer of soil, it is one form of soil degradation.

Water erosion:

Queensland’s high intensity summer rainfalls represent a significant risk of erosion by water.

Raindrops hit bare soil with enough force to break the soil aggregates. These fragments wash into soil pores and prevent water from infiltrating the soil. Water then accumulates on the surface and increases runoff which takes soil with it.

Sheet and rill erosion:

Hill slopes are prone to sheet erosion and rill erosion. The amount of hill slope erosion largely depends on how the land is used.

Sheet erosion occurs when a thin layer of topsoil is removed over a whole hillside paddock—and may not be readily noticed.

Rill erosion occurs when runoff water forms small channels as it concentrates down a slope. These rills can be up to 0.3m deep. If they become any deeper than 0.3m they are referred to as gully erosion.

Answer 2

Answer:

soil erosion is displacement of the upper layer of soil,it is one form of soil degradations.

Explanation:

the agent of soil erosion is are the same of other types of erosion: water,ice,wind,& gravity.

soil erosion is more likely where the ground has been disturbed by agriculture, grazing animals logging mining, construction and recreational activities.
