During chemical weathering, rocks could then suck up CO2 when some minerals were attacked by the weak acid in rainwater. This process could counter the continuous CO2 production from volcanoes and ...

Weathering is the mechanical and chemical hammer that breaks down ... forming an acidic concoction that dissolves rock. For example, acid rain dissolves limestone to form karst, a type of terrain ...
