  • Q2

    The removal of rock in solution by acidic water.

    Oxidation

    Hydrolysis

    Freeze-thaw

  • Q6

    It occurs when water continually seeps into cracks, freezes, and expands eventually breaking the rock apart.

    Solution

    Expoliation

    Freeze-thaw

    Hydrolysis

    30s
  • Q7

    It occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.

    Solution

    Hydrolysis

    Exfoliation

    Freeze-thaw

    30s
  • Q8

    Bacteria, algae and lichens produce chemicals that help break down the rock on which they live, so they can get the nutrients that they need.

  • Q9

    This process occur more rapidly at higher temperature, so warm, damp climates are best.

  • Q10

    It happens especially in places where there is little soil and few plants grow, such as in mountain regions and hot desserts.

    Physical Weathering

    None of the above
