* On the surface of the Earth: This is the most common location for weathering. Rocks exposed to the elements, like mountains, cliffs, or even your backyard, will experience weathering.
* Underground: Weathering can also happen underground, though it's less visible. This can occur in caves, underground mines, or even deep within the Earth's crust.
Key takeaway: Rock weathering is a process that happens where the rock exists, whether it's on the surface or buried underground.
