Lab questions chapter 10
The dynamic equilibrium model refers to
a balancing act between tectonic uplift and rates of reduction in a given landscape
Which of the following is incorrectly matched?
abrasion- a hydraulic squeeze and release action
Stream drainage patterns are determined by which of the following
all of these
The rate at which rocks weather depends upon
all of these
Which of the following can initiate hillslope failure
all of these
Which of the following is incorrectly matched
allegheny and missouri rivers- form the monongahela at Pittsburgh
Which of the following features indicates that a stream has undergone uplift and rejuvenation
alluvial terraces
Which of the following is NOT exogenic in nature
batholith formation
If earth did not experience endogenic processes, the landscape would
be of very low relief as a result of weathering and erosion in the absence of uplift
floodplain
flat, low-lying area flanking many stream channels that is subjected to recurrent flooding
Conflicting forces work to establish an optimum incline on a slope. When any of these conditions are disturbed or altered, the materials on the slope reach a
geomorphic threshold, or change point
In which of the following climates would the subsurface line of contact between weathered and unweathered materials be at the greatest depth
hot and wet
denudation
is any process that wears away or rearranges land forms
geomorphology
is the science of landforms, the science of their origin, evolution and spatial distribution.
Which of the following rock types most affected by fluvial solution
limestone
In most areas, the upper surface of bedrock is partially weathered to broken-up rock called
regolith
A persistent mass movement of surface soil is called a
soil creep
a landslide from a debris avalanche in that
the materials in a landslide are not saturated with water
What role do rivers play in the hydrolic cycle
they provide us with essential water supplies, they receive,dilute, and transport wastes and provide critical cooking water for industry.
Which of the following landforms is incorrectly matched with a drainage pattern
topographically disrupted areas- parallel
Stream width, depth, and velocity are all responsive to discharge rates
true
The balancing act between tectonic uplift and reduction of the landscape by weathering and erosion, between the resistance of crust materials and the attack of denudation processes, is summarized in the dynamic equilibrium model.
true
Other than the rock itself, the most important chemical substance needed for the majority weathering processes is
water
