Earth Science Deposition Quiz

What is the primary difference between weathering and erosion?

• Weathering involves the transportation of sediments.

• Erosion involves the breakup of sediments.

• Erosion is the process of sediments settling.

• Weathering is the breakup of sediments, while erosion is their transportation.

How do glaciers and gravity typically organize sediments?

• They create sorted and layered sediments.

• They produce unsorted and unlayered sediments.

• They organize sediments by size and shape.

• They only affect sediment density.

Which factor does NOT affect the rate of sediment deposition?

• Size of the sediment fragments

• Color of the sediment fragments

• Density of the sediment fragments

• Shape of the sediment fragments

What is horizontal sorting?

• Sediments are organized from bottom to top.

• Sediments are organized from top to bottom.

• Sediments are organized by color.

• Sediments are organized from largest to smallest as a river enters an ocean.

What is a river delta?

• A triangular feature formed at the mouth of a river.

• A circular feature formed in the middle of a river.

• A rectangular feature formed at the source of a river.

• A linear feature formed along the riverbank.

What is graded bedding?

• A feature found only in deserts.

• A method of organizing sediments by color.

• A pattern of vertical sorting in landslides.

• A type of horizontal sorting in rivers.

What is the main feature of wind deposition?

• Formation of river deltas

• Formation of alluvial fans

• Formation of dunes

• Formation of graded bedding

How do dunes typically migrate?

• By animals moving the sand

• By gravity pulling them downhill

• By wind moving sand from the windward to the leeward side

• By water currents

What is cross bedding?

• A feature found only in glaciers

• A method of organizing sediments by size

• A pattern of sediment layers that change direction

• A type of horizontal sorting in rivers

What is the role of plants in dune areas?

• To change the color of the sand

• To create new dunes

• To stabilize dunes and prevent them from moving

• To increase the speed of dune migration
