Q

A combination of particles of rocks, minerals, and organic matter produced through weathering processes.

A

Soil

25
Q

refers to the transportation of rock, soil and mineral particles from one location to another.

A

Erosion

26
Q

Main driving force behind all agents of erosion

A

Gravity

27
Q

final step in the erosional- ______ system

A

deposition

28
Q

As glaciers move over the land they acts as a “bulldozer” changing the view of the landscape

A

Glacial Deposition

29
Q

Earth material is broken down by processes of weathering and erosion, and is transported by the action of wind, water, or ice, and/or by the force of gravity

A

Depositional Environment

30
Q

Deposited on land or in fresh water

A

Terrestrial/Continental

31
Q

Deposited in an environment showing influence of both fresh water or air and marine water.

A

Transitional

32
Q

Only influenced by sea water.

A

Marine

33
Q

Processes associated with rivers and streams

A

Fluvial

34
Q

Loose, unconsolidated soil or sediments

A

Alluvium

35
Q

Desert areas cover about what percent of land surface

A

20-25%

36
Q

The removal of loose, find-grained particles by the turbulent action of the wind

A

Deflation

37
Q

The wearing down of surfaces by the grinding action by windborne particles

A

Abrasion

38
Q

Are perpendicular to the prevailing wind and form a wave like pattern

A

Traverse

39
Q

stretch parallel to the prevailing wind with rounded or pointed tops

A

Longitudinal dunes

40
Q

A curved, arc shaped sand mound with horns facing downwind formed in arid regions

A

Barchans

41
Q

These are U-shaped mounds that form in the reverse direction of a barchans.

A

Parabolic

42
Q

These are most commonly found on beaches and are sandy depressions in a sand dune caused by the removal of sediments by wind

A

Blowout

43
Q

The lightest material carried by the winds which form a so-called blanket covering the existing land

A

Loess

44
Q

Desert alluvial fan, broad surface area, fine grained

A

Bajada
