If a fusion reaction produces no appreciable radioactive isotopes, why does a hydrogen bomb produce significant radioactive fallout?
A. The radioactive fallout is a result of the fission reaction used to ignite the thermonuclear fusion reaction. B. It is a misconception that fusion reactions produce no appreciable radioactive isotopes. Therefore, radioactive fallout is unavoidable. C. Once a hydrogen bomb is exploded, all matter within nearly 100 miles becomes radioactive fallout. D. The fallout is only the radioactive remnants of the bomb's structure and casing.
What is the name for the kind of glacial landform illustrated by Mt. Gibbs? (On the topographic map, the dashed black line showing the boundary between Mono and Tuolumne Counties runs through the summit of Mt. Gibbs.)
The question is based on Map T-13, the “Mono Craters, California” quadrangle (scale 1:62,500; contour interval 80 feet), and Figures 48-5 and 48-7, a detailed map and stereogram, and Map T-23a, a satellite image, of the same region. The heavily glaciated eastern crest of the Sierra Nevada is seen along the western sides of the map and stereograms (37°52'37"N, 119°12'40"W). During the Pleistocene, glaciers in this region flowed down the valleys on the eastern slope of the Sierra toward the Mono Lake basin to the northeast. Large lateral moraines are found at the mouths of each canyon. What will be an ideal response?
Which of the following is not true of dry climates?
A) Dry climates are generally located in bands immediately to the north and south of the low-latitude humid climates. B) Many dry regions are associated with the subtropical high pressure zone. C) Some deserts are caused mainly by mountain ranges that isolate land from ocean sources of moisture. D) Arid climates have severe moisture shortages year round, while most semiarid climates have a rainy season in which sufficient moisture is available for abundant, if brief, vegetation growth. E) Both arid and semiarid regions lack sufficient moisture and heat to make any plants grow for more than a month each year.
