WebThe geology of an area influences the rate of river erosion. For example, rivers flowing over hard rock have a slower erosion rate as the bedrock is more resistant. However, areas with soft rock are more likely to experience higher rates of erosion. Those landscapes consisting of more resistant rocks are more likely to have steeper valley sides ... WebFactors that affect the rate of landform change in a river are: Geology – such as hard and soft rocks in the formation of a waterfall. Climate – in the UK this varies with seasons, and...
WebWhy is erosion a problem? Rates of erosion vary in places due to a mixture of human and physical factors. These can change in short and long term. There are three main reasons … WebHere, we compile, normalize, and compare published 10 Be erosion rate data ( n = 1599) in order to understand how, on a global scale, geologic erosion rates integrated over 10 3 to 10 6 years vary between climate zones, tectonic settings, and different rock types. Drainage basins erode more quickly (mean = 218 m Myr −1; median = 54 m Myr −1 ...
