Environmental & Atmospheric Sciences - Regional Geography Courses,ge101. Quiz Grade 2

1
The direction of geostrophic winds is influenced by pressure gradients, the Coriolis effect, and friction.
2
Major water pollution problems can arise when nitrogen stimulate the growth of algae and phytoplankton.
3
Most green plants only need about 10 to 30 percent of full summer sunlight for maximum net photosynthesis.
4
Mammals are well adapted to desert environments, and as a result there a large number of species that inhabit arid regions.
5
Sympatric speciation occurs where populations are geographically isolated and gene flow between the populations does not take place.
6
Plants and algae use light energy to convert carbon dioxide and water into carbohydrates and are referred to as primary consumers.
7
The only biogeochemical cycle of any significance is the carbon cycle.
8
Duration and intensity of light vary with latitude and season and serve as a cue to initiate the growth stages in many plants.
9
Although many different species may occupy the same habitat, only a few of these species will ever share the same ecological niche.
10
Generally, the number of organisms and their total amount of living tissue decreases greatly up the food chain.
11
Net photosynthesis is the total amount of carbohydrates produced by photosynthesis before respiration breaks down the carbohydrate to power the plant.
12
Swamps and estuaries are ecosystems with high rates of net primary production, while grasslands and agricultural lands are lower.
13
Succession on coastal sand dunes can follow a series of stages from dune grass to oak and holly forests.
14
The average net primary production for land-based ecosystems is always greater than marine-based ecosystems.
15
Xerophytes are plants that have a difficult time existing in arid environments.
16
In midlatitude regions, photosynthesis continues in most plants even on overcast days.
17
Ecological biogeography examines the distribution patterns of plants and animals from the viewpoint of ecological factors and the interrelationships between species.
18
Widely distributed or cosmopolitan species include Homo sapiens, bats, rats, and goats.
19
Highland climates at low latitudes are normally cooler and wetter than the surrounding lower-altitude climates.
20
Low-latitude climates are occasionally invaded by air of polar origins.
21
The moist subtropical climate experiences abundant rainfall with a winter maximum.
22
The dry subtropical climate includes BWh, BWk, BSh, and BSk as subtypes.
23
Wheat is the dominant crop of the moist subtropical climate type.
24
Colder regions generally have lower precipitation than warmer regions.
25
The smaller area of tropical deserts in the southern hemisphere is due to different wind regimes.
26
The marine midlatitude west coasts are located between 35 and 60 degrees latitude.
27
Coastal stations show a larger annual variation in temperature, while the variation is smaller for stations in continental interiors.
28
A steppe is a vast expanse of semiarid grassland.
29
The ice sheet climate type experiences no true summer but a short, mild season with temperatures above freezing.
30
Orographic precipitation occurs on mountainous coasts exposed to moist trade winds or frequent cyclonic storms.
31
Dry tropical climates are dominated by low pressures associated with the ITCZ.
32
Midlatitude climates are strongly influenced by the frontal interactions between traveling air masses.
33
The isolines on a map describing average precipitation are referred to as isohyets.
34
Low-latitude rainforests possess a lower diversity of plants and animals compared to higher-latitude forests.
35
Boreal forests are characterized by needleleaf trees.
36
The climate of the Sahara Desert can be classified as BSh.
37
Steppes are associated with wet-dry tropical climates.
38
Permafrost may be found in tundra regions and in a wide bordering area of the boreal forest climate.
39
The Mediterranean climate is characterized by vegetation such as sclerophylls.
40
A winter precipitation maximum is characteristic of both the Mediterranean climate and the marine west-coast climate.
41
The dry midlatitude climate experiences a smaller annual temperature range than the marine west-coast climate.
42
The Asiatic monsoon climate experiences a dry season when dry air flows southwest in the low-Sun season.
43
Which of the following landform definitions is CORRECT?
