This is a quiz on river systems facts! Rivers are streams of water that flow in channels and drain into larger water bodies. As the river flows, many things happen to the water or the river beds. Do you know the journey one river takes as the water heads for the outlet? This quiz will help polish your knowledge. Do give it a shot and see how well you do!
- 1.Why can high-gradient streams move large sediment particles?
- A.
Because high-gradient streams can exert large forces on the stream bed.
- B.
Because it makes the stream flow go faster.
- C.
Because it can make cupcakes.
- D.
Because of downcutting.
- E.
None of the above.
- 2.What is stream discharge?
- A.
Erosion of a valley by a stream.
- B.
The area of a river valley next to the channel, which is built of deposited sediments and is covered with water when the river overflows its banks at flood stage.
- C.
The volume of water passing a point along the river in a unit of time.
- D.
A term used for a small stream.
- E.
None of the above
- 3.
- 4.Why do high-gradient streams cause downcutting of their valleys?
- A.
None of the Below
- B.
Because since high-gradient streams cut their valleys vertically downward, they go too rapidly to widen out to form floodplains.
- C.
Because since high-gradient streams can exert large forces on the stream bed, they tend to erode their valleys rapidly.
- D.
Both B & C
- E.
None of the Above

The large particles in the stream.
- 9.Why do low-gradient streams have a broad flood plain?
- A.
None of the Below.
- B.
Because they shift sides through the meandering.
- C.
Because of the amount of sediment in aquifer

- C.
Meandering
- D.
When the stream channel can not contain the discharge & water that is passing through it.
- E.
The amount of stream flow downward in a high-gradient stream.
