Colorado Plateau

The main reason that flash floods occur in Zion National Park is:

sunbaked soils don't absorb water, which runs off rather than infiltrates

Zion National Park is best known for its:

Slot canyons

The main characteristic of a flash flood is:

Decreased lag time between a storm and stream discharge

Arch formation is most greatly influenced by which process?

Alternate freezing and thawing

One of the largest influences in the formation of Mt. St. Helens National Park was:

The lateral blast nature of the eruption

Most of the rocks exposed in the Colorado Plateau national parks were formed where?

The Cretaceous Seaway

Yellowstone

Most geologists think that Yellowstone will not erupt again in about 100,000 years. About how long ago was the last Yellowstone super eruption?

630,000 years

Quaternary age geological materials would be found in which of the following National Parks?

a. Grand Canyon

b. Mt. Rainier

c. Hot Springs

d. Great Smoky Mountains

(All of the above)

An increase in atmospheric CO2 may be causing temperatures to increase in our National Parks. This temperature increase results in more or less precipitation in some regions of the USA, which causes changes in the flow of many streams that further result in changes to the biota present in those streams. This is an example of what?

Gaia Hypothesis

The Cascadian Fault generates many features of our Northwestern USA national parks. This fault is a result of which tectonic feature?

Subduction Zone

he main rock type in Yosemite is derived from what? (Note - this was one of our rocks of the day --- oooh)

Granite plutons formed deep in the earth's crust

Material deposited by melting glaciers creates landforms such as those found in Rocky Mountain National Park, known as:

Moraines

Unloading of overlying rock material releases pressure and causes expansion of granitic bodies, resulting in "sheeting" or slabbing in granite common in the Sierra Nevada. This is called:

Exfoliation

Yosemite Falls is an example of a glacial landform called a (an):

Hanging Valley

The most significant environmental issue at most of our western national parks) is:

Air quality

Sediment replenishment

Partially compacted nevé might be found where:

Glacier National Park

A mudflow resulting from the melting of snow and glacial ice due to heat from volcanic activity, such as those that have come from Mt. Rainier and Mt. St. Helens, is called a:

Lahar

The most important physical weathering process in arctic, high alpine, and regions with many cycles of freezing and thawing (e.g., Yosemite National Park, Great Smoky Mountains, etc. is:

Frost action

Many of our national parks are threatened by a natural gas extraction process that can cause earthquakes, pollute groundwater, and contaminate the surface environment. This process is called:

Hydrofracking

Which of the following is the oldest?

The water in your bottled water

What is proppant?

Mount Mazama formed from magma generated by the subduction of the Juan de Fuca Plate under the North American Plate. Its eruption formed:

Crater Lake

Which of the following weathering processes significantly helps form hoodoos?

Frost

An area consisting of more than six thousand vertical feet of alternating cliffs, slopes, and terraces which extends horizontally about 150 miles from the north rim of the Grand Canyon in northern Arizona to the top of the Paunsaugunt Plateau in southern Utah is known as:
