    4. DFrost Shattering
    5. EPressure Release
    6. FExfoliation
  2. 2[blank_start]Burrowing[blank_end] = The action of holes being dug by invertebrate and [blank_start]vertebrate[blank_end] animals that mixes and [blank_start]brings[blank_end] to the surface rock and [blank_start]soil[blank_end] particles. This [blank_start]facilitates[blank_end] weathering at greater depth by providing access for [blank_start]atmospheric[blank_end] gases and [blank_start]water[blank_end].

  6. 6Frost shattering:
    Water enters [blank_start]cracks[blank_end], joints and bedding planes.
    In climates where daily [blank_start]temperature[blank_end] fluctuate above and below [blank_start]0oC[blank_end], water freezes and expands by [blank_start]9%[blank_end].
    This exerts [blank_start]pressure[blank_end] on rocks, producing a residue of angular fragments called [blank_start]scree[blank_end].    Imagen de la pregunta 6

  7. 7[blank_start]Exfoliation[blank_end]:
    - Aka. onion-skin weathering.
    - Different [blank_start]minerals[blank_end] expand and contract by different [blank_start]amounts[blank_end] during heating and cooling, causing the rock to [blank_start]disintegrate[blank_end].
    - [blank_start]Curved[blank_end] sheets [blank_start]peel[blank_end] off from the rock.    Imagen de la pregunta 7
    1. AExfoliation
    2. Bminerals
    3. Camounts
    4. Ddisintegrate
    5. ECurved
    6. Fpeel
  8. 8Pressure Release:
    Atmospheric [blank_start]pressure[blank_end] at the Earth's surface is much lower than pressures within the Earth.
    Pressure is released from rock due to [blank_start]erosion[blank_end] of the rocks above them.
    Rocks expand, producing [blank_start]fractures[blank_end] which are more widely [blank_start]spaced[blank_end] the [blank_start]further[blank_end] they are from the surface.
    Rocks that are well [blank_start]jointed[blank_end] or have many bedding planes are [blank_start]less[blank_end] affected.    Imagen de la pregunta 8
    1. Apressure
    2. Berosion
    3. Cfractures
    4. Dspaced
    5. Efurther
    6. Fjointed
    7. Gless
  9. 9Carbonation:
    [blank_start]Carbon dioxide[blank_end] gas in the atmosphere reacts with rainwater and [blank_start]pore[blank_end] water in the soil to form [blank_start]carbonic[blank_end] acid.
    The air in pore spaces is rich in carbon dioxide due to decomposing [blank_start]plant[blank_end] litter.
    This makes groundwater more acidic than rainwater which then reacts with [blank_start]carbonate[blank_end] minerals in the rock.
    1. ACarbon dioxide
    2. Bpore
    3. Ccarbonic
    4. Dhydrochloric
    5. Eplant
    6. Fanimal
    7. Gcarbonate
  10. 10Carbonation Equation:
    [blank_start]CaCO3[blank_end] + H2CO3 --> [blank_start]Ca2+[blank_end] + 2HCO3-
    Calcite + [blank_start]Carbonic acid[blank_end] --> Calcium + [blank_start]Hydrogen carbonate[blank_end] ions in solution.
    1. ACaCO3
    2. BCa2+
    3. CCarbonic acid
    4. DHydrogen carbonate
