Q:

How does soil erosion happen?

A:

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.

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 is wind erosion?

    A:

    By definition, wind erosion involves the erosion, transportation and deposition of soil by the wind, according to Dictionary.com. Wind erosion is often worse during dust storms. Poor farming practices by humans combined with drought conditions such as occurred during the 1930s in the United States increase wind erosion.

  • Q:

    How is wind erosion different from water erosion?

    A:

    Wind erosion happens when pieces of the Earth are worn away by strong winds over time, and water erosion happens when moving water such as ocean waves wear away rock instead of seeping into the ground. Water is a more powerful erosion force than wind.

  • 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:

    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.
