Deposition and Sediment Characteristics Quiz

What is the process called when sediments are released and settled from an erosional system?

• Sedimentation

• Deposition

• Weathering

• Erosion

Which factor does NOT affect the rate of deposition?

• Color of the sediments

• Size of the sediments

• Characteristics of the sediments

• Velocity of the erosional agent

What is the minimum size of a boulder according to the sediment size chart?

• 0.1 cm

• 0.2 cm

• 25.6 cm

• 6.4 cm

Which sediment size requires the highest stream velocity to be carried?

• Clay

• Boulders

• Silt

• Pebbles

How does the shape of a sediment affect its settling time?

• Both settle at the same rate

• Round sediments settle faster

• Shape has no effect

• Flat sediments settle faster

What type of relationship exists between sediment shape and rate of deposition?

• No relationship

• Direct relationship

• Cyclic relationship

• Inverse relationship

What is the relationship between the density of sediments and their rate of deposition?

• Denser sediments settle slower

• Denser sediments settle faster

• Density has no effect

• Less dense sediments settle faster

Which of the following is NOT a characteristic of sorted sediments?

• Organized by size

• Organized by shape

• Organized by color

• Organized by density

Which erosional agents are associated with sorted sediments?
