Fluvial Processes, Patterns and Landforms

Which of these is not a way a river shapes the landscape over which they flow?

• Erosion

• Transportation

• Eroded material (deposition)

• Gradient

How well a river erodes the landscape depends on?

• Gradient

• Discharge

• Shape of the river channel

• All of the above

Exogenetic forces are processes that occur at or near the Earths surface, an example would be erosion from..

• Wind

• Water

• Ice

• All 3

Wetter perimeter is the length of the rivers bed and banks that is NOT in contact with the river.

• True

• False

Velocity is also another term for speed.

• Yes

• No

River erosion vertically will deepen the river ben while lateral erosion will widen it.

• True

• False

Force of moving water. More turbulent the water - faster the erosion. Bank Caving can occur. Cavitation is also active.

• Hydraulic Action

• Abrasion

• Solution

• Attrition

Load of a river hits off its bed and banks. Hollows deepen further due to eddying.

• Hydraulic Action

• Abrasion

• Solution

• Attrition

Chemical Breakdown of rocks due to acids contained in water.

• Solution

• Saltation

The rounding of the stones and pebbles carried by the river as they knock off each other and off the bed and banks.

• Nutrition

• Attrition

• Corrosion

• None of the above
