Explanation:
Detailed explanation-1: -Biological Weathering Causes Roots of plants and trees delve into the soil in quest of moisture and nutrients. The joints or cracks in the rocks are traversed by the roots as they move through the soil, gradually rupturing the rock.
Detailed explanation-2: -Root Pry: Plants and plant roots also tend to pull rock apart (a form of mechanical weathering). Roots follow nooks and crannies along in the subsurface and, as they get older, expand. Root expansion pulls and pries apart rock.
