Deposition

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass. It occurs when the forces transporting the materials lose energy and can no longer carry the load.

How does angularity affect the settling rate of a particle in water?

Back

As angularity increases, settling rate decreases.

Front

How does size affect the settling rate of a particle in water?

Back

As size increases, settling rate increases.

Front

What is vertical sorting in sediment deposition?

Back

Vertical sorting occurs when sediments are deposited in layers based on their size, with larger particles settling first and smaller particles settling later.

What happens to sediments when a river enters the ocean?

Back

Larger sediments are deposited near the mouth of the river, while smaller sediments are carried further away.

Front

What is the order of sediment deposition when a stream flows into a lake?

Back

Pebbles, sand, silt, then clay.

Front

What is the relationship between particle shape and settling rate?

Back

More angular particles have a lower settling rate compared to round particles due to increased surface area and friction.

Front

Define sediment. What are its components?

Back

Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, consisting of particles such as sand, silt, clay, and gravel.

What is the significance of sediment size in deposition?

Back

Sediment size affects how quickly and where sediments are deposited; larger particles settle faster than smaller ones.

Front

What is cross-bedding in sedimentary rocks?

Back

Cross-bedding is a geological feature where layers of sediment are deposited at an angle to the horizontal, indicating changes in current direction.
