Q:

How does soil erosion happen?

Soil erosion is caused when elements such as wind and rain remove surface soil. The eroded soil is then carried away and deposited by the wind or rain.

Full Answer

Plants help bind soil together with their roots and reduce soil erosion by providing shelter from wind and rain. Accelerated soil erosion occurs when the soil is eroded faster than it can reform. Topsoil is nutrient-rich and forms the top layer of the soil. When soil erosion occurs, topsoil is the first layer to be removed, resulting in a lower quality, less habitable soil. Less plants grow where the topsoil has been removed, resulting in further erosion of the soil.

  • Q:

    What are wind and water erosion not likely to affect?

    A:

    Wind and water erosion are least likely to affect igneous sills and cooled lava flows. Limestone, basalt and quartzite are also unlikely to undergo erosion or weathering, as are sandstone and chert. Soil and soft rocks such as clays erode very quickly without protection.

  • Q:

    What are types of wind erosion?

    A:

    The three main types of wind erosion are suspension, saltation and creep. Suspension is the blowing of tiny particles into the air where they may be carried for long distances, saltation is the repeated lifting and dropping of slightly larger particles, and creep is the movement of particles too large to lift along the ground. All types only occur with relatively dry, loose soils that wind can break apart.

  • Q:

    What are examples of wind erosion?

    A:

    According to the CK-12 Foundation, the most common examples of wind erosion are rock formation and desert varnish. Wind erosion can also affect much smaller rocks and structures, as evidenced by the desert pavement in the Mojave Desert.

  • Q:

    How does wind erosion occur?

    A:

    Wind erosion occurs in dry, bare areas when wind blows and moves dirt around. It damages crops by removing soil from the crops that need it and putting it somewhere else.
