____ occurs when water freezes in rock fractures
Frost wedging
Material deposited by streams is called alluvium.
True
The ____ develops around a central elevated point; this pattern is common to such conically shaped features such as volcanoes.
Radial drainage pattern
Dry locations tend to be dominated by what type of weatheing?
Physical
Root and frost wedging are examples of chemical weathering.
False
The process of chemical weathering tends to.
Lower the density of minerals

False
Karst develops in regions underlain by limestone and to a lesser extent dolomite.
True
Mass movement is the down slope movement of earth materials under the influence of water run off.
False.
Stream erosion includes the detachment of material from the bed or sides of the channel.
True
_____ is the breakdown and decomposition of earth material, namely rocks.
Weathering
____ incurs no change in the chemistry of the material being altered. Instead, it simply breaks large pieces into smaller pieces.
Physical weathering.
A ______ is one that takes twists and turns over its length.
Meandering channel.
The fundamental unit of study for fluvial processes is the drainage basin or watershed.
True.
The fact that people who live on the oregon coast experience more rust damage, especially on their vehicles relates to the text's contention that moist lications are dominated by chemical weathering, more than dry locations.
True
Which of the following chemical weathering processes is more permanent.
Hydrolosis
What is the slowest type of mass movement?
Creep
The colorado river, which is an exotic stream, does not flow into the ocean due to the fact that.
The river's flow has been diverted for municipal and agricultural uses.
Mass movement is the down slope movement of earth materials under the influence of gravity.
True.
Material deposited by streams is called alluvium
True
Sinkholes are commonly funnel shaped and broadly open downward.
False
Perennial streams only flow part of the year.
True
Flow velocity controls the streams capacity to erode and transport sediment through its channel.
True
Weathering involves the decomposition of rocks and sediment.
True
Which of the following are types of mass movement?
Soil creep
Which of the following is the most common drainage pattern and looks like the branching of tree roots?
Dendritic drainage pattern
Physical weathering is also called mechanical weathering.
True.
