Description

Landscapes

Weathering and erosion are very closely related topics. Describe how these two processes can shape the landscape and be sure to provide examples. You may choose to discuss an individual form of weathering and erosion or concentrate on a given area such as deserts, glaciated areas, or river systems and the forms of weathering and erosion that occur there.

Your paper should meet the following requirements:

It is strongly recommended that you submit all assignments to the TurnItIn Originality Check prior to submitting the assignment to your instructor for grading.

The Impact of Weathering and Erosion on Landscape

Weathering and erosion are two geological processes that work together to shape the
earth’s surface. Weathering refers to the process of decomposing, changing the color, and
breaking up of rocks (Hoffman, 2011). It is the decomposition of rocks, minerals, and soils
that are caused by coming into contact with the atmosphere. Weathering may be occasioned
by the activities of animals, plants, chemicals, and water. It occurs in two processes: chemical
weathering and mechanical weathering. Chemical weathering entails the chemical variances
in rock minerals. It can also involve changes on the surface of the rock that lead to a change
in the shape or color of the rock. Chemical weathering is caused by carbon dioxide, water,
oxygen, and acids may contribute to chemical weathering.
Mechanical weathering, on the other hand, occurs when rocks physically break into
portions but the chemical composition of the rock’s minerals remain intact (Gifford, 2005). In
this sense, we can say that mechanical weathering involves the process whereby large rocks
are broken into smaller fragments without any change in the minerals...
