Question

question 1-4
what happens to a rock formation that undergoes a repeated and frequent freeze and thaw cycle of water?
○ sinkholes form which is part of the chemical weathering process.
○ deposition occurs which is part of the chemical weathering process.
○ abrasion occurs which is part of the mechanical weathering process.
○ ice wedging occurs which is a part of the mechanical weathering process.

Explanation:

The freeze-thaw cycle involves water expanding when freezing (ice) and contracting when thawing. This repeated expansion/contraction within rock cracks breaks the rock, which is ice wedging—a mechanical weathering process. Sinkholes form from dissolution (chemical), deposition is sediment accumulation, and abrasion is physical scraping (not freeze-thaw).

Answer:

Ice wedging occurs which is a part of the mechanical weathering process.
