Stream Dynamics and Particle Movement Quiz

What happens to the velocity of a stream as the size of the particles it carries increases?

• The velocity decreases because larger particles create more resistance.

• The velocity increases because larger particles have more momentum.

• The velocity remains unchanged because particle size does not affect stream velocity.

• The velocity increases initially but decreases after reaching a critical particle size.

Which of the following sediment sizes would most likely be transported in a fast-moving stream?

• Clay

• Silt

• Sand

• Pebbles

During which process are particles of rock and soil carried away by a stream?

• Deposition

• Erosion

• Compaction

• Cementation

What is the primary factor that affects the amount of sediment a stream can carry?

• The color of the sediment

• The stream's velocity

• The pH level of the water

• The temperature of the water

Which of the following is NOT a factor affecting stream flow?

• Gradient or slope of the stream bed

• Volume of water in the stream

• The type of fish living in the stream

• The amount of vegetation along the stream banks

How does the size of particles relate to the process of erosion in a stream?

• Larger particles are eroded more easily than smaller particles.

• Smaller particles are eroded more easily than larger particles.

• Particle size has no effect on erosion.

• Only particles of a specific size are eroded, while others remain unaffected.

What is the term used to describe the dropping of sediments as a stream's velocity decreases?

• Erosion

• Deposition

• Infiltration

• Transpiration

Which of the following would most likely occur in a section of a stream with a very high velocity?

• Large deposition of sediments

• Significant erosion of the stream bed

• No movement of sediments

• Formation of meanders

What effect does vegetation along stream banks have on erosion and sediment transport?

• It increases erosion by trapping water.

• It decreases erosion by stabilizing the soil.

• It has no effect on erosion or sediment transport.

• It increases sediment transport by adding organic matter to the stream.

In terms of sediment transport, what is the main difference between a youthful stream and a mature stream?

• A youthful stream can transport larger particles than a mature stream.

• A mature stream can transport larger particles than a youthful stream.

• A youthful stream only transports liquid sediments, while a mature stream can transport solid particles.

• There is no difference in the types of sediments they can transport.
