Term
The soil that is remaining after the soluble elements have been dissolved.
A) Residum
B) Loess
C) Moraines
D)Delta
Definition
A) Residum
Term
Poorly sorted rock fragments detached from heights above and carried downslope. These materials are usually coarse and stony because of physical weathering and not chemical weathering.
A) Moraines
B) Deltas
C) Colluvial
D) Loess
Definition
C) Colluvial
Term
Unconsolidated soil material consisting largely of undecomposed, or only slightly decomposed, organic matter accumulated under conditions of excessive moisture.
A) Loess
B) Organic deposits (peats)
C) Moraines
D) Residum
Definition
B) Organic deposits (peats)
Term
An alluvial deposit formed where a stream or river drops its sediment load upon entering a quieter body of water.
A) Deltas
B) Kames
C) Loess
D) Drumlins
Definition
A) Deltas
Term
Fan-shaped alluvium deposited at the mouth of a canyon or ravine where debris laden waters fan out, slow down, and deposit their burden.
Definition
Alluvial Fans
Term
Material transported and deposited by wind and consisting of predominantly silt-sized particles.
A) Deltas
B) Kames
C) Moraines
D) Loess
Definition
D) Loess
Term
An accumulation of drift, with an initial topographic expression of its own, built within a glaciated region chiefly by the direct action of glacial ice.
A) Deltas
B) Eskers
C) Drumlins
D) Moraines
Definition
D) Moraines
Term
Material deposited in lake water and later exposed either by lowering of the water level or by the elevation of the land.
A) Peats
B) Lacustrine
C) Eskers
D) Residuum
Definition
B) Lacustrine
Term
A conical hill or ridgenof sand or gravel deposited in contact with glacial ice.
A) Eskers
B) Kames
C) Drumlins
D) Loess
Definition
B) Kames
Term
A narrow ridge of gravelly or sandy glacial material deposited by a stream in an ice-walled valley or tunnel in a receding glacier.
A) Eskers
B) Kames
C) Drumlins
D) Residum
Definition
A) Eskers
Term
Long, smooth, cigar-shaped low hills of glacial till, with their long axes parallel to the direction of ice movement.
A) Eskers
B) Kames
C) Drumlins
D) Residum
Definition
C) Drumlins
Term
List 3 examples of physical weathering processes.
Definition
Rocks can be worn down by temperature change(makes rocks expand and contract then break), windblown sand (like sandpaper), ice glaciers embedded with soil and rock fragments (wears rocks down).
Term
Which type of weathering process usually dominates in arid areas?
Definition
Physical
Term
Which type of weathering process usually dominates in humid areas?
Definition
Chemical
Term
Describe Igneous Rocks.
Definition
They are molten magna;volcanic in nature. They have lots of silicone in them.
Term
Describe Sedimentary Rocks.
Definition
They are materials that weathered from other rocks that glue back together.
Term
Describe Metamorphic Rocks.
Definition
These are rocks that have been changed, usually by high pressure and temperatures below the Earth's surface. These rocks are very difficult to weather.
Term
Which type of rock do we find mostly here in Southwest Missouri?
Definition
Sedimentary
