Aim
: How can we define
erosional

environments and identify factors of
deposition?

Do Now
: Determine relationships for
direct and indirect graphs.

Erosion
:

The process by which
weathered sediments are
carried and transported.

Agents of Erosion
:

Force or material that moves
earth materials from one place
to another.

Agents of erosion include:


Running Water


Glaciers


Wind


Wave Action


Gravity (Mass Movement)

Deposition
:

The release of
sediments from an
erosional

system;
also known as
sedimentation.

The ultimate result of deposition is a
decrease in velocity in a
erosional

system.

Factors that Affect Deposition

1.
Size
: As the sediment size
increases, the rate of deposition
increases.




Relationship: Direct

Time for
Deposition

Size of Sediments

Rate of
Deposition

2.
Density
: As the density of
sediment increases, the rate of
deposition increases.

3.
Shape
: As the sediment surface
area increases, the rate of
deposition decreases.
