Virginia Earth science Deposition

​ (a)   is part of a system in which sediments carried by a transporting agent ( ​ (b)   ) are dropped from the medium because the system loses ​ (c)   .

Deposition is also called​ (d)   .

​ (e)   is the predominant transporting agent.

The ​ (a)   particles settle more slowly than the larger particles, because as the ​ (b)   of a stream slows, the larger and usually heavier particles drop the fastest because they are pulled down by ​ (c)   .

The smaller particles tend to remain in ​ (d)   for longer periods of time, settling more slowly.

Which of these particles will float indefinitely as long as there is even the slightest movement of the transporting agent?

• Solution

• Suspension

• Colloid

Which shape of sediment will sink the slowest?

• Flat thin rock

• Flat thick rock

• Round shaped rock

Which will sink the fastest

• Low density rock

• high density rock

• medium density rock

As the ​ (a)   of a sediment laden flow ​decreases , the particle of ​ (b)   settle out first. This decreasing velocity results in ​ (c)   sorting.

When a stream enters another body of water such as the ocean, the heavier particles ​ (d)   , and the ​ (e)   settle further out into the ocean.

• velocity
• greater weight and density
• horizontal
• settle out first
• lighter particles

Which form of sediment would settle first in the ocean?

• Pebbles

• Sand

• Silt

• Clay

What winds up forming clay in the ocean?

• Pebbles

• Sand

• Silt

Which moves the fastest?

• Transporting agent (Water or wind)

• Particle movement (sediment)

(a)   refers to the variation in (b)   size across a flat plane, like a riverbed, where larger particles tend to be found in one area and smaller particles in another, while (c)   describes the change in sediment size from the top to the bottom of a sediment layer, with (d)   particles usually settling at the bottom and (e)   particles on top due to gravity

• horizontal sorting
• sediment
• vertical sorting
• coarser
• finer
