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].

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.
- AExfoliation
- Bminerals
- Camounts
- Ddisintegrate
- ECurved
- Fpeel
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.
- Apressure
- Berosion
- Cfractures
- Dspaced
- Efurther
- Fjointed
- Gless
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.- ACarbon dioxide
- Bpore
- Ccarbonic
- Dhydrochloric
- Eplant
- Fanimal
- Gcarbonate
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.- ACaCO3
- BCa2+
- CCarbonic acid
- DHydrogen carbonate
11Carbonation is important in the weathering of [blank_start]limestone[blank_end].
[blank_start]Limestone[blank_end] generally contains insoluble [blank_start]impurities[blank_end] which are left behind as clay [blank_start]residues[blank_end].- Alimestone
- BLimestone
- Cimpurities
- Dresidues
12Name the three methods of sediment transport in water:

18[blank_start]Attrition[blank_end] = the wearing down of sedimentary grains due to [blank_start]collisions[blank_end] with other grains during transport.
[blank_start]Abrasion[blank_end] = the wearing away of the Earth's surface by the action of the wind, water or ice [blank_start]dragging[blank_end] sediment over it or hurling it at the surface.- AAttrition

- CErosion
- DTraction

19Erosion = the wearing away of the land surface and the removal of sediment by means of transport.

20Saltation = the transport of the smaller grains in the [blank_start]bed load[blank_end] by [blank_start]bouncing[blank_end] the along the [blank_start]bed[blank_end].
Suspension = the transport of material in the [blank_start]suspended[blank_end] load of a water based transport medium, [blank_start]without[blank_end] it touching the Earth's surface.- Asuspended
- Bbed load
- Cbed
- Dbouncing
- Ewithout
21Solution = the transport of [blank_start]ions[blank_end] dissolved in [blank_start]water[blank_end].

- this method of transportation is [blank_start]invisible[blank_end] so can not be shown on a diagram- Aions
- Bwater
- CCa
- Dinvisible
22Clay particles require high velocities for erosion because they are [blank_start]flat[blank_end], [blank_start]platy[blank_end] and [blank_start]cohesive[blank_end] so tend to stick together.
Clay particles remain in [blank_start]suspension[blank_end] even at low current velocities because they are [blank_start]small[blank_end], have a [blank_start]low[blank_end] mass and are [blank_start]buoyant[blank_end].- Aflat
