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
