Let's review. Chemical weathering is the process by which rocks are broken down by chemical reactions. There are different types of chemical weathering. Hydrolysis is the chemical breakdown of a substance when combined with water.The most common example of hydrolysis is feldspar in granite rocks changing to clay.his is a very slow process because lichens are slow-growing and the acid they produce is very weak. However, this is a common type of chemical weathering near rivers and streams. So we see that lichens break down rock by producing acid and we see a similar phenomenon with acid rain.
