Question

Quizplus · Accepted Answer

Spheroidal weathering is the process by which jointed rocks with sharp edges and corners are gradually rounded and smoothed as a result of chemical and physical weathering. This occurs as water penetrates into the fractures and weathering agents chemically react with the rock, causing the corners and edges to break down and round off.
