Column B
a.A chemical process in which carbon dioxide dissolves into water, producing carbonic acid
b.The slow cracking of rock by having water seep into cracks and expand when it freezes
c.The smoothing of rock by multiple collisions of particulate matter being pushed along by water or wind
d.A chemical process in which matter reacts with oxygen, typically creating a more brittle substance afterwards
