Answer:
In order for granite to undergo weathering and erosion, the process of physical and chemical weathering is necessary.
Step-by-step explanation:
Physical weathering involves the breakdown of rocks into smaller pieces through processes like frost wedging and abrasion. Chemical weathering, on the other hand, involves the alteration of the rock's composition through chemical reactions with substances like water and acids. These processes weaken the granite, making it more susceptible to erosion by wind, water, or ice.
