• A)

• B)

• C)

• D)

Four quartz samples of equal size and shape were placed in a stream. Which of the four quartz samples below has most likely been transported farthest in the stream?

• A)

• B)

• C)

• D)

What is the minimum water velocity necessary to maintain movement of 0.1-centimeter-diameter particles in a stream?

• 0.02 cm/s

• 0.5 cm/s

• 5.0 cm/s

• 20.0 cm/s

Sediment is deposited in a river delta because the

• A) velocity of the river decreases

• B) force of gravity decreases

• C) volume of the river increases

• D) gradient of the river increases

A stream's velocity decreases from 100 cm/s to 5cm/s. Which size sediment particles will still be transported by the stream?

• pebbles, sand, silt, and clay

• sand, silt, and clay, only

• silt and clay, only

• clay, only

Base your answer to the following question on the map below, which shows the generalized bedrock of a part of western New York State. As the Niagara River enters Lake Ontario, the velocity of the river water:

• decreases and larger sediments are deposited first

• decreases and smaller sediments are deposited first

• increases and larger sediments are deposited first

• increases and smaller sediments are deposited first

The block diagram below shows a part of the eastern coastline of North America. Points A, B, and C are reference points along the coast. Which list best represents the primary processes occurring along the coastline at points A, B, and C?

• A) A — folding; B — subduction; C — crosscutting

• B) A — weathering; B — erosion; C — deposition

• C) A — faulting; B — conduction; C — mass movement

• D) A — precipitation; B — infiltration; C — evaporation

Base your answer to the following question on the map below, which shows a portion of the continent of North America and outlines the Mississippi River watershed. Points A, B, C, D, and E represent locations on Earth's surface.Sediments deposited by the river at location B are best described as:

• sorted and layered

• sorted and not layered

• unsorted and layered

• unsorted and not layered

The diagram below shows a laboratory stream table. A mixture of sediment was placed on the stream table. A short time after the faucet was turned on, a deposit of sediment began forming at location X at the lower end of the stream table.What is the name of the stream feature forming at location X?

• V-shaped valley

• meander

• delta

• floodplain

Which cross section best represents the pattern of sediments deposited on the bottom of a lake as the velocity of the stream entering the lake steadily decreased?
