Physical processes

One way in which water can transport sediment is through traction. Which verb best describes traction?

• Rolling

• Bouncing

• Floating

• Dissolving

One way in which water can transport sediment is through saltation. Which verb best describes saltation?

• Rolling

• Bouncing

• Floating

• Dissolving

As water moves over the land, either as a river or waves from the sea, it has the ability to erode the land, transport the sediment eroded and eventually _________ the sediment.

Weathering is the action of elements of the weather that breakdown the land. Which of the following is NOT an element of weather?

• Precipitation

• Temperature

• Wind

• Waves

There are 4 types of erosion. Which type is best described as the sheer force of water entering cracks in rocks and forcing them to break apart?

• Hydraulic action

• Abrasion

• Attrition

• Solution

There are 4 types of erosion. Which type is best described as "the constant knocking together of sediment being carried by water that makes the sediment smoother and smaller"?

• Hydraulic action

• Abrasion

• Attrition

• Solution

There are 4 types of erosion. Which type is best described as "the sandpapering effect caused by sediment scraping against rocks as it is carried in the water"?

• Hydraulic action

• Abrasion

• Attrition

• Solution

One type of mechanical weathering is....

• Carbonation

• Freeze-thaw

• Hydraulic action

• Saltation

Carbonation breaks down alkali rocks because....

• Rain water is mildly acidic

• Water freezes in cracks

• Water is forced into cracks

• Carbon dioxide reacts with the rock

Waves are created by the wind. Which 3 of the following will determine the strength of the wave?

• Wind speed

• Length of time the wind blows

• Distance over which the wind blows (the fetch)

• The direction the wind blows
