Depositional Environments

The picture shows a pattern of horizontal sorting when a sediment-laden stream enters the ocean. Deposition of these sediments occurs when a stream enters the ocean because the stream current

• decreases in width

• decreases in kinetic energy

• increases in potential energy

• increases in velocity

The diagrams show two views of the same river flowing from a lake to an ocean bay. How do the size and density of the particles deposited in Dolphin Bay generally change as distance from the shoreline increases?

• Both size and density decrease

• Both size and density increase

• Size decreases and density increases

• Size increases and density decreases

The moraine deposits left when this glacier melts will generally be

• sorted by size and layered

• sorted by size and unlayered

• unsorted by size and layered

• unsorted by size and unlayered

Where is the most deposition likely to occur?

• On the side of a sand dune facing the wind

• At the mouth of a river, where it enters an ocean

• At a site where glacial ice scrapes bedrock

• At the top of a steep slope in a stream bed

A meandering stream deposits most of its sediments on the

• inside of meanders where the stream flows faster

• inside of meanders where the stream flows slower

• outside of meanders where the stream flows faster

• outside of meanders where the stream flows slower

Pieces of bedrock material that are broken from a cliff and deposited by a landslide at the base of the cliff are best described as

• rounded and sorted

• rounded and unsorted

• angular and sorted

• angular and unsorted

A sedimentary particle is dropped into a cylinder of water. The particle will take the longest time to settle if the particle has

• low density, small size, and spherical shape

• low density, small size, and flattened shape

• high density, large size, and spherical shape

• high density, large size, and flattened shape
