Q:

How are canyons formed?

A:

Quick Answer

Canyons are formed by wind and water erosion over a long period of time after a large hill, mountain or plateau is formed. The original land mass is formed by tectonic plates colliding and causing tectonic uplift, and the weakest of material is worn down over time to create a deep, narrow ravine called a canyon.

Full Answer

The most common type of canyon is a river canyon; running water wears down the rock formation on either side and carries it away. Additionally, in colder climates, water can seep into rock, freeze and expand to break down further rock and dirt.

    How are floodplains formed?

    A:

    The Center for Earth and Environmental Science describes that floodplains are formed as rivers erode their own banks. Floodplains are the flat lands that lie adjacent to a river; they encompass the area that floods when the river's water level rises. As the river flows, it washes material downstream. When a flood occurs, this material is resuspended in the water and added to the floodplain.

  • Q:

    How are landforms formed?

    A:

    Landforms are formed by movements of the earth, such as earthquakes, weathering, erosions and deposits. Many landforms are created by more than one of these processes. These are called polygenetic landforms.
