Choose the best possible answer to the following questions about Key Concept 7 "Energy from sedimentary rocks'."

This activity contains 12 questions.

Fossil fuels are those that form from the ___________.

U.S. government buildingsoxidized remains of iron-bearing materialremains of organic material (carbon)remains of inorganic material (silicon)

Why are “coal” and “petroleum” products considered to be “fossil fuels”?

their energy content was derived from “ancient” sunlight, trapped in the materialcoal beds and petroleum reservoir rocks contain abundant fossilstheir oxygen and nitrogen contents were derived from the ancient atmospherecarbon dioxide, released when they burn, contributes to the greenhouse effect

Which of the following accounts for the majority of the coal burned annually in the United States?

manufacturing processing in the production of steelproduction of carbon black, synthetic diamondsfor home and industrial space heatingto generate electricity

Oil and gas become “trapped” in which of the following due to buoyancy?

a. at the cores of arched stratified layersb. at the cores of depressed stratified layersc. at salt domesboth a. and b. both a. and c.

Match the type of oil and gas trap with its description:

A matching question presents 4 answer choices and 4 items. The answer choices are lettered A through D. The items are numbered 5.1 through 5.4. Screen readers will read the answer choices first. Then each item will be presented along with a select menu for choosing an answer choice. Using the pull-down menus, match each item in the left column to the corresponding item in the right column.

	a sloping bed of reservoir rock thins to the point of disappearance
	risen blobs and columns of rock deform the rock around by “poking” it upward causing oil and gas to migrate there
	where dipping reservoir rock is brought into position opposite an impermeable bed, trapping oil and gas at the interface
	an uparched series of sedimentary strata cause oil and gas to migrate to the center

5.1 stratigraphic trap
5.2 salt dome trap
5.3 fault trap
5.4 anticline trap

The diagrams are of "oil and gas traps." The top left one is an "anticlinal" trap (see next question). Match the labels on the diagrams with the appropriate description:

The letters A through G appear on an image associated with this question.

This question presents 7 items numbered 6.1 through 6.7. Each item is presented with a pulldown menu containing the letters A through G. For each item below, use the pull-down menu to select the letter that labels the correct part of the image.

6.1 reservoir rock (aquifer)
6.2 example of a "stratigraphic" trap
6.3 example of a "fault" trap
6.4 aquitard (cap rock)
6.5 example of a "dome" trap
6.6 fault
6.7 salt diapir

Identify the elements of the illustrated anticlinal oil trap by selecting the correct response.

The letters A through D appear on an image associated with this question.

This question presents 4 items numbered 7.1 through 7.4. Each item is presented with a pulldown menu containing the letters A through D. For each item below, use the pull-down menu to select the letter that labels the correct part of the image.

7.1 water
7.2 oil
7.3 cap rock
7.4 gas

Match the type of oil and gas trap with the description of its formation:

A matching question presents 4 answer choices and 4 items. The answer choices are lettered A through D. The items are numbered 8.1 through 8.4. Screen readers will read the answer choices first. Then each item will be presented along with a select menu for choosing an answer choice. Using the pull-down menus, match each item in the left column to the corresponding item in the right column.

	bent strata
	forms primarily from the original pattern of sedimentation, rather than structural deformation
	when strata are displaced in such a manner as to bring a reservoir rock in contact with a cap rock
	low-density rock at great depth forces its way upward through rocks, deforming them in a “poking” fashion

8.1 stratigraphic trap
8.2 salt dome trap
8.3 fault trap
8.4 anticline trap

Why is it that the country of Saudi Arabia is the largest current producer of crude oil?

much of the rocks within the boundaries of the country act as a structural trapthe government resells much of the oil produced in the other countries of the Middle Eastmuch of the rocks are oil shale and oil sandthe government pumps oil from off shore, in the Persian Gulf and Indian Ocean

Relative to shale, sandstone is a much more common reservoir rock for petroleum because of which of the following?

sandstone is more abundant than shalesandstone is more permeable than shale, so fluids may flow through it fastershale is more porous so the oil tends to leak out over timeshale, especially black shale, is much richer in primary organic matter than is sandstone

Which of the following is most likely correct?

Coal imports into the U.S.A. have been rising steadily since about 1950. North and South America have about equal reserves of good-grade coals. By 2010, imported petroleum will account for over half of the U.S.A. consumption. By the year 2010, Russia and the other components of the former Soviet Union will probably be importing large amounts of petroleum from South Africa.

Identify the North American source of each of the indicated resources by selecting the correct response.

The letters A through C appear on an image associated with this question.

This question presents 3 items numbered 12.1 through 12.3. Each item is presented with a pulldown menu containing the letters A through C. For each item below, use the pull-down menu to select the letter that labels the correct part of the image.

12.1 bituminous coal
12.2 anthracite coal
12.3 tar sands
