The term that best identifies the type of weathering represented by a salt crystal growing in a crack in a rock is mechanical weathering. This occurs when physical forces, such as the growth of salt crystals, exert pressure on rocks causing them to break apart or crack.
When any type of rock undergoes weathering, it usually forms sedimentary rock. Weathering breaks down existing rocks into smaller pieces that get deposited and compressed to form sedimentary rocks over time.
Concentric weathering, also known as spheroidal weathering, is a type of physical weathering that occurs on rocks with uniform composition. It involves the gradual wearing away of outer layers of rock, resulting in the formation of onion-like layers or spheres on the surface of the rock. This type of weathering is commonly seen on boulders and large rock outcrops.
Chemical weathering
Hydration
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.

Acrylic latex paint is the best choice for pressure treated wood due to its durability and ability to withstand moisture and weathering.

The best type of caulk to use for sealing concrete cracks is a polyurethane-based caulk. It is durable, flexible, and provides a strong seal that can withstand movement and weathering.
