Select from the dropdown lists to complete the text.

Frost shattering:
Water enters ( cracks, burrows, structures ), joints and bedding planes.
In climates where daily ( temperatures, pressures, windspeeds ) fluctuate above and below ( 0oC, 5oC, -2oC ), water freezes and expands by ( 9%, 7%, 12% ).
This exerts ( pressure, force, tension ) on rocks, producing a residue of angular fragments called ( scree, shards, breccia ).

:
- Aka. onion-skin weathering.
- Different expand and contract by different during heating and cooling, causing the rock to .
- sheets off from the rock.

Question 8 of 23

1

Fill the blank spaces to complete the text.

Pressure Release:
Atmospheric at the Earth's surface is much lower than pressures within the Earth.
Pressure is released from rock due to of the rocks above them.
Rocks expand, producing which are more widely the they are from the surface.
Rocks that are well or have many bedding planes are affected.

Explanation

Question 9 of 23

1

Carbonation:
❌ gas in the atmosphere reacts with rainwater and ❌ water in the soil to form ❌ acid.
The air in pore spaces is rich in carbon dioxide due to decomposing ❌ litter.
This makes groundwater more acidic than rainwater which then reacts with ❌ minerals in the rock.

Explanation

Question 13 of 23

1

How does ice transport sediment?

Select one of the following:

It pushes it.
The sediment is embedded within it.

Explanation

Question 14 of 23

1

Select the 2 correct facts about traction.

Select one or more of the following:

It is the transport of material by rolling and sliding along a surface.
It is the transport of material by bouncing.
It occurs in the suspended load.
It is the transport of material in water or air without it touching the Earth's surface.
It occurs in the bed load.

Explanation

Question 15 of 23

1

Select one of the following:

Wind
Gravity
Rivers
Sea
Ice

Explanation

Question 16 of 23

Select one of the following:

True
False

Solution = the transport of dissolved in .
- Particularly K, , Na
- this method of transportation is so can not be shown on a diagram

Explanation

Question 22 of 23

1

Select from the dropdown lists to complete the text.

Clay particles require high velocities for erosion because they are ( flat, round ), ( platy, sheety, buldgey ) and ( cohesive, repellent ) so tend to stick together.
Clay particles remain in ( suspension, saltation, traction, solution ) even at low current velocities because they are ( small, medium, big ), have a ( low, high ) mass and are ( buoyant, gaseous ).
