  1. 4-3. weathering, erosion, transportation and sedimentation • 4-3-1. Weathering • Breakdown of rocks (minerals) and others on the surface of water (due to the surface conditions) • Physical (mechanical), chemical, (biotic) weathering

  2. Physical weathering –due to physical forces • Temperature change • Freezing (frost wedging) • Pressure change • Hydraulllic action • Mineral growth • Others: plant roots etc.
