Which type of weathering helped to form annete lake ?physical weathering/chemical weathering and explain why

Physical weathering

Explanation:

There is continued interest on accurate estimation of natural weathering rates owing to their importance in soil formation, nutrient cycling, estimation of acidification in soils, rivers and lakes, and in understanding the role of silicate weathering in carbon sequestration. At the same time a challenge does exist to reconcile discrepancies between laboratory-determined weathering rates and natural weathering rates.

there all right good
