• erosion
• deposition
• mouth
• divide

An area which drains into a common river system.

• watershed
• tributary
• drainage divide
• riparian zone

As the current in a stream becomes stronger, what will happen to its erosional power?

• it will increase
• it will decrease
• it will stay the same
• it will increase then decrease

As the velocity of a stream decreases, what happens to the size particles that it is able to carry?

• It's only able to carry larger particles
• It's only able to carry smaller particles
• It can carry any size particles

Valleys created by downcutting streams are ___- shaped

• W
• U
• V
• Y

How does a sinkhole form?

• Stalactites erode a ceiling of a cave
• Streams in mountains erode sediment
• Underground water forms a cave
• Stream erodes soil making it wider

Which graph best represents the relationship between the discharge of a stream and the velocity of stream flow?

• 
• 
• 
• 

Higher velocity discharge (volume of water):

• depends on a watershed.

• depends on a confluence.

• has bigger particles and more particles that flow through it.

• has smaller particles and less particles that flow through it.

At which stage would a river have a lot of sediment deposition?

• old

• mature

• youthful

• rejuvenated

Youthful rivers often have

• meanders

• rapids

• flood plains

• sandbars
