Final answer:
Canada's granite is more at risk of damage from acid rain, which occurs when pollutants mix with water vapor and fall as rain, eroding rock surfaces and depleting soil nutrients.
Step-by-step explanation:
Canada's large amount of granite in its geography makes it more at risk to be damaged by acid rain. Granite, being a type of igneous silicate rock that comprises much of Earth's continental crust, is particularly vulnerable to chemical weathering processes that are exacerbated by acid rain. When sulfur dioxide and nitrogen oxides from the combustion of fossil fuels are emitted into the atmosphere, they can mix with water vapor to form acids that precipitate as rain. This acid rain can erode granite surfaces, deplete soil nutrients, and damage both natural and human-made structures.
