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
