Chemical weathering controls erosion rates in rivers
Chemical weathering controls erosion rates rivers
2016/4/25
Chemical weathering can control how susceptible bedrock in river beds is to erosion, according to new research. In addition to explaining how climate can influence landscape erosion rates, the r...
