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 ...
