Why does it take a long time for granite to break down?

Answer 1

Granite takes a long time to break down due to its composition and structure. It is primarily made up of hard minerals like quartz and feldspar, which are highly resistant to weathering and erosion. Additionally, granite's crystalline structure makes it less susceptible to chemical weathering compared to softer rocks. The process of breaking down granite into soil or sediment involves both physical and chemical processes that occur over extended periods, often spanning thousands to millions of years.
