which process is responsible for changing the composition of rock?\n○ erosion\n○ abrasion\n○ chemical weathering\n○ mechanical weathering

Answer

Brief Explanations:

To determine the process changing rock composition, analyze each option:

  • Erosion: Transports rock, doesn’t change composition.
  • Abrasion: Mechanical scraping (physical change, no composition shift).
  • Chemical weathering: Involves chemical reactions (e.g., oxidation, hydrolysis) that alter mineral composition.
  • Mechanical weathering: Breaks rock into smaller pieces (physical, no composition change).

Only chemical weathering modifies rock’s chemical makeup.

Answer:

C. chemical weathering
