Q:

What are the four types of erosion?

A:

Quick Answer

The four types of erosion are sheet erosion, rill erosion, gully erosion and splash erosion. Erosion is defined as the withering away of the surface of land by either rain or irrigation water, wind or ice.

Full Answer

Sheet erosion occurs when a very thin layer of surface dirt or soil is removed from a large area. The result of rill erosion is a set of small channels viewed on a slope that are caused by running water. Gully erosion exists when larger and wider channels are cut out of slopes by running water. Splash erosion is caused by the movement of splashing water.

  • Q:

    What are some different types of erosion?

    A:

    Erosion is caused by water, wind and ice. All types of rock and soil are affected by erosion. It is a natural process, although it can be influenced by the actions of people.

  • Q:

    What are some types of coastal erosion?

    A:

    The four types of coastal erosion are solution, hydraulic action, abrasion and attrition. Solution erosion occurs when the ocean’s water is acidic. The acidic water causes some of the rocks along the beach to dissolve into the water. Chalk- and limestone-based coastlines are particularly susceptible to this type of erosion.

  • 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 the four types of weathering?

    A:

    The four main types of weathering include freeze-thaw, exfoliation, chemical and biological weathering. Weathering involves the process of rock breaking down into soil via various physical, biological and chemical reactions.
