Rocks and Sediments Weather at Different Rates

2 of 5

Factors that Impact the Speed of Weathering

  • If it is harder rock it will erode slower.
    • This can cause different features at the surface of earth.

Factors that Impact the Speed of Weathering

Type of Rock Being Weathered

  • Some rocks (example- limestone) react with acidic water more than others.

4 of 5

Temperature

  • Warmer areas have more chemical weathering (reactions speed up when it’s warmer).
  • Wet environments generally speed up chemical weathering.
  • Areas that vary in temperature (highs and lows) usually have more physical weathering.

Amount of Surface Area Exposed

  • If a rock has more surface area exposed it will weather faster.
