Question

How do rocks absorb carbon dioxide?

Answer 1

Known as enhanced rock weathering, the process involves layering crushed rock onto soil. When silicate or carbonate minerals in the dust dissolve in rain water, carbon dioxide is drawn from the atmosphere into the solution to form bicarbonate ions.

Answer 2
