Question

c. make a list of 6 forces that can weather a rock physically or chemically (6 points)

1. _____________ 2. ___________ 3. _____________
2. _____________ 5. ___________ 6. _____________

Explanation:

Physical weathering forces break rocks without changing their chemical composition. Chemical weathering forces change the rock's chemical makeup. Water (through processes like freeze - thaw where water seeps into cracks, freezes (expands), and thaws, breaking the rock physically), wind (carries sand and other particles that abrade the rock surface physically), temperature changes (cause rocks to expand and contract, leading to physical breakage), plants (roots grow into cracks, exerting pressure and breaking rocks physically), animals (burrowing animals can break rocks physically), and oxygen (reacts with minerals in rocks, for example, iron in rocks can oxidize (rust) chemically).

Answer:

1. Water (physical - freeze - thaw), 2. Wind (physical - abrasion), 3. Temperature changes (physical - expansion/contraction), 4. Plants (physical - root growth), 5. Animals (physical - burrowing), 6. Oxygen (chemical - oxidation)
