How Weathering and Erosion Shape Landscape
Question
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.
SAMPLE SOLUTION
Weathering and erosion are processes within geomorphology, a study of nature and the origin of landforms that occur in hydrosphere and atmosphere. Erosion and weathering chisel polish and buff rocks of the earth into evolving works of art and then wash the remains into other places. Particularly, weathering changes rocks from a hard state to weaker and softer ones which can then be grounded and transported to other places by erosion, hence shapes the surface or the landscape of the earth. This paper, therefore, describes how soil erosion and weathering shapes surface by specifically looking at wind erosion in deserts.
Wind erosion is a term used to refer to the damage of land as a result of wind blowing and carrying materials, especially soil from one place to the other. According to Dove (2016), it is a solemn environmental issue which has attracted the attention of many people across the globe since it transforms the natural landscape of the earth which then cause other side effects to both animals and plants. Basically, soil movement is started when wind forces are exerted against the surface of the ground. For every surface condition and soil type, there is a velocity which is required to move soil particles from one point to other. This is known as the threshold velocity. When this velocity has been reached, the amount of soil transported depend on the cloddiness of particles, the particle size, and wind velocity itself. What has become the most concern of several people is how it changes the earth surface and transforms the landscape.
