Question

question 1 20 pts process by which rocks and minerals undergo changes in their composition due to chemical reactions with agents such as acids, water, oxygen, and carbon dioxide chemical weathering mechanical weathering exfoliation dls chu datlvjaj

Explanation:

To solve this, we analyze each option:

• Chemical weathering involves rocks/minerals changing composition via chemical reactions with agents like acids, water, oxygen, CO₂. This matches the description.
• Mechanical weathering is physical breakdown (no composition change).
• Exfoliation is a type of mechanical weathering (peeling due to pressure change).
• The last option is unclear/incorrect.

Answer:

A. chemical weathering
