Q
Freeze thaw
A
water gets into well jointed rocks-freezes-expands by 10%-pressure of around 2100 kg/cm (squared£ shatters rock

A
chemical weathering process: dissolves calcium carbonate in limestones. carbon dioxide dissolved in water forms a weak carbonic acid which when reacts with calcium carbonate=bicarbonate=dissolves
