Which one among the following processes is NOT part of chemical weathering?

CONCEPT:

Chemical Weathering

• Chemical weathering refers to the breakdown of rocks and minerals through chemical reactions, resulting in the formation of new minerals and soluble salts.
• Common processes involved in chemical weathering include solution, hydration, and reduction.
• These processes alter the chemical composition and structure of the rocks.

EXPLANATION:​

• Solution:
  • This process involves the dissolving of minerals in water, leading to the formation of a solution.
• Hydration:
  • This process involves the absorption of water into the mineral structure, causing the mineral to expand and weaken.
• Reduction:
  • This process involves the gain of electrons by a mineral, often leading to changes in its chemical composition.
• Thawing:
  • This process involves the melting of ice or frozen ground, which is a physical change rather than a chemical one.

Therefore, the process NOT part of chemical weathering is Thawing.
