Sediment Transport and Stream Dynamics

The video tutorial explains the process of erosion by running water, highlighting how weathering of rock produces particles that are transported by erosion. It covers the formation of channels by runoff, the transport of sediments in streams, and the creation of V-shaped valleys and deltas. The tutorial also discusses factors affecting stream velocity and the role of meanders in erosion and deposition.

What is the primary result of weathering of rock?

• Change in rock color

• Increase in rock size

• Creation of rock particles

• Formation of new rocks

What is the term for water that flows across the ground without soaking in?

• Precipitation

• Runoff

• Evaporation

• Infiltration

How are small soil particles initially moved by runoff?

• By gravity

• By animal activity

• By runoff carrying them downhill

• By wind

What is the term for the amount of sediment carried by a stream?

• Sediment capacity

• Sediment volume

• Stream load

• Water load

Which type of sediment is most easily suspended in water?

• Pebbles

• Clay

• Sand

• Gravel

What shape do rivers typically form over time due to erosion?

• V-shaped valleys

• U-shaped valleys

• Circular basins

• Flat plains

What is a delta?

• A type of river

• A fan-shaped deposit of sediment

• A mountain range

• A type of erosion

Which factor does NOT affect the velocity of a stream?

• Temperature

• Channel shape

• Discharge

• Gradient

Where is the maximum velocity of water in a straight stream?

• Near the banks

• At the edges

• At the bottom

• In the center near the surface

What happens to sediments on the inside of a river meander?

• They are eroded

• They bounce

• They are deposited

• They dissolve
