Looking at the long profile of the river's course, where does most erosion occur? (a)
In the river process, (a) is when material is worn away from the river bed and banks.
In the river process, (a) is when material is dropped into the river channel.
In the river process, (a) is when material is carried away along with the river flow, to another place.

What is the name of the point where a river starts? (a)
An oxbow lake is an old (a)
What landform is created on the inside bend (...) of a meander and why?
(a)
What landform can be found on the outside bend of a meander(*) and why?
A river cliff as the water flows slowly and deposits the load it is carrying.
A river cliff as the water flows quickly on the outside bend eroding the bank through attrition.
A river cliff
A river cliff as the water flows quickly on the outside bend eroding the bank through hydraulic Action.
Where will there be the most erosion? (a)
Where is the water in the river moving the slowest? (a)
Which of the following is NOT very typical of a youthful stage of a river? (a)
Erosion is most likely greatest at locations (a)
Which two locations have the greatest stream velocities? (a)
At which two locations would the stream most likely be the deepest? (a)
The streambank on the outside of this meander is steeper than the streambank on the inside of this meander because the water on the outside of this meander is moving (a)
The river undercuts the hard rock, creating an overhang. (a)
"Water cuts into the rock and wears it away," This is called...
sediment
deposition
erosion

Waterfalls are landforms created by....
Erosion
Deposition
Over time the top rock sticks out over the bottom rock. It is unsupported and so eventually (a) into the plunge pool

Bands of hard and soft rock
Fast flowing water
River sediment
The waterfall retreats (moves back) upstream towards the rivers source over thousands of years leaving behind a steep sided (a)
What is the FIRST step in a water fall formation?
Hard rock
Soft rock
If a river flows over a hard rock and then a soft rock the soft rock will be eroded more.
Which statement is NOT TRUE about waterfalls? (a)
The water in waterfalls can erode the land around it. But many other forces can also erode the earth. What is one way the gravity can erode earth?
By creating electricity that Canadians and Americans can use to power their homes

How do groynes work to protect the coastline?
They trap sediment by slowing down longshore drift, thereby building up a wide beach
They absorb wave energy so that the cliffs behind are protected
