• cold and wet

The map shows the top view of a meandering stream as it enters a lake. At which points along the stream are erosion and deposition dominant?

• Erosion is dominant at A and D, and deposition is dominant at B and C.

• Erosion is dominant at B and C, and deposition is dominant at A and D.

• Erosion is dominant at A and C, and deposition is dominant at B and D.

• Erosion is dominant at B and D, and deposition is dominant at A and C.

The particles in a sand dune deposit are small and very well-sorted and have surface pits that give them a frosted appearance. This deposit most likely was transported by

• ocean currents

• glacial ice

• gravity

• wind

Which geologic evidence would best support the inference that a continental ice sheet once covered a given location?

• polished and smooth pebbles; meandering rivers; V-shaped valleys

• scratched and polished bedrock; unsorted gravel deposits; transported boulders

• sand and silt beaches; giant swamps; marine fossils found on mountaintops

• basaltic bedrock; folded, faulted, and tilted rock structures; lava flows

A mixture of colloids, clay, silt, sand, pebbles, and cobbles is put into stream I at point A. The water velocity at point A is 400 centimeters per second. A similar mixture of particles is put into stream II at point A. The water velocity in stream II at point A is 80 centimeters per second. Which statement best describes what happens when the particles are placed in the stream?

• Stream I will move all particles that are added at point A.

• Stream II will move all particles that are added at point A.

• Stream I cannot move sand.

• Stream II cannot move sand.

A mixture of colloids, clay, silt, sand, pebbles, and cobbles is put into stream I at point 4. The water velocity at point 4 is 400 centimeters per second. A similar mixture of particles is put into stream II at point 4. The water velocity in stream II at point 4 is 80 centimeters per second. If a sudden rainstorm occurs at both streams above point A, the erosion rate will

A mixture of colloids, clay, silt, sand, pebbles, and cobbles is put into stream I at point 4. The water velocity at point 4 is 400 centimeters per second. A similar mixture of particles is put into stream II at point 4. The water velocity in stream II at point 4 is 80 centimeters per second. In lake I, as the stream water moves from point C to point D, its velocity

To investigate the effects of abrasion on limestone rock chips, students placed rock chips of uniform size and shape in jars half-filled with water and shook them for different lengths of time. One rock chip was collected for each length of shaking time and these chips were arranged in a display. Which column below shows the rock chips arranged from top to bottom in order of least to most shaking time?

• Column 1

• Column 2

• Column 3

• Column 4

Transported sediments are usually deposited at locations in which

• the freeing and thawing of water occurs

• the chemical breakdown of rocks occurs

• a decrease in the speed of the agent of erosion occurs

• an increase in the physical weathering of rocks occurs

Compared to a low-density spherical particle, a high-density spherical particle of the same size will sink through water

• more slowly

• more rapidly

• at the same rate

• density is not a factor in the settling rate of a particle
