Geography Exam 2

John Wesley Powell put forward the idea of base level, which refers to

a level below which a stream cannot erode its valley

Any large cave formed by chemical processes is a

cavern

A sinkhole that develops over a period of hours or days and forms from a collapse through the roof of an underground cavern is known as

collapse sinkhole

A meandering stream is one that

completely stable

Processes that are related expressly to streams and rivers are termed

fluvial

If material is to move downslope, it must overcome the force of

friction, cohesion of particles, and intertial resistance

The suspended load of a stream consists of particles that are

held aloft in the stream flow

The science of water and its global circulation, distribution, and properties is known as

hydrology

The area of land from which all water in it drains into the same place known as

interfluve

Continuing dissolution and collapse may led to coalescing of sinkholes to form a

karst valley

The downslope of movement of a body of material made up of soil, sediment, or rock

slide

Which of the following is not a class of mass movement

slip

A slow persistent mass movement of surface soil is called

soil creep

a slope is _____ if its strength exceeds denudation processes and ____ if its materials are weaker than denudation processes.

stable, unstable

Stream capture refers to

the process by which one channel erodes through a drainage divide and captures the headwater regions of another stream.

Plants are important to the development of karst primarily because

they supply organic acids that enhance the dissolution process

Which of the following are examples of dripstones

only stalacities and stalagmites are examples of dripstones

The presence of talus slopes indicates that ____ occurs

rockfalls

Which of the following can lead to the slop failure that causes mass movement

saturation, oversteeping of slopes, earthquakes, and volcanic eruptions

The ultimate base level is

sea level

Stream transport involves all of the following except

sheet flow

If the load exceeds a stream's capacity, sediment accumulates in the bed in a process called

aggradation

Which of the following human activities can contribute to mass movement?

any human disturbance of a slop, including roadcuts, surface mining, and development.

When rainwater attacks formations of limestone, the minerals dissolve and wash away with the mildly acid rainwater. This is an example of

carbonation

Cones and cockpit karst develop in

cold, midlatitude climates

The degradation of a landscape by weathering, erosion, and transportation

continental shelf

The sediment load that travels is solution is

dissolved load

Of the worlds largest rivers, which has the greatest discharge

Amazon River

Which of the following was NOT a contributing factor in the January 2018

Approximately 0.5 inches of rain fell in just five minutes

Parts of the flow behaved as debris flow because

any of these choices are correct

Which of the following is not necessary for well developed karst to develop?

arid conditions

The largest material that can be carried by a stream is carried as

bed load

The total possible load a stream can transport is its

capacity, competence

The drainage pattern is associated with steep slopes

parallel

A central peak, such as a volcanic mountain, generally produces a ________ drainage pattern.

radial

The drainage pattern results when streams flow off a central peak or dome

radial
