In which layer of Earth's atmosphere does most weather occur?
Which of the following best explains why polar regions are colder than tropical regions?
polar regions receive less solar energy per unit of surface area
Which of the following statements about patterns of temperature and precipitation is NOT correct?
along Earth's surface, the air of a Hadley cell moves away from the equator
Which of the following processes is NOT characteristic of oceanic circulation?
counterclockwise gyres in the northern hemisphere
Which of the following statements about rain shadows is correct?
as air rises over a mountain range, water vapor condenses into precipitation
Why do scientists use dominant plant growth forms to categorize terrestrial biomes?
similar plant growth forms are found in climates with similar temperatures and amounts of precipitation
Which information is NOT found in climate diagrams?
average annual humidity
Which of the following statements about tundra and boreal forests is correct?
boreal forests have larger dominant plant growth forms than tundras
Which of the following statements about temperature biomes is not correct?
temperate biomes have average annual temperatures about 20 degrees C
Which of the following statements about tropical biomes is correct?
tropical rainforests have the highest precipitation due to the proximity of the ITCZ
Which of the following is NOT a measure of diversity?
The table below represents the number of individuals of different species that were counted in three forest communities. Which of the following statements BEST interprets this data?
Community C has greater species richness than community A
Which of the following is an example of artificial selection?
thoroughbred racehorses have been bred for speed
The yellow perch is a fish that breeds in spring. A single female can produce up to 40,000 eggs in one time. This species is an example of which of the key ideas of Darwin's theory of evolution by natural selection?
individuals produce an excess of offspring
In 2002, Peter and B. Rosemary Grant studied a population of Darwin's finches on one of the Galipagos Islands that feed on seeds of various sizes. After a drought that caused only large seeds to be available to the birds, they found that natural selection favored those birds that had larger beaks and bodies. Once the rains returned and smaller seeds became much more abundant, however, natural selection favored those birds that have smaller beaks and bodies. Which of the following processes is the BEST interpretation of this scenario?
The northern elephant seal was once hunted to near extinction. Only 20 animals remained alive in 1890. After the species was protected from hunting, its population grew to nearly 30,000 animals, but the large population possesses very low genetic variation. Which of the following processes is the BEST explanation of this scenario?
evolution by the bottleneck effect
Which of the following statements is NOT correct?
speciation cannot occur without geographic isolation
Which of the following allows more rapid evolution?
high genetic variation
Which of the following conditions does NOT define the fundamental niche of a species?
Some scientists estimate that the current global extinction rate is about 30,000 species per year. If there are currently 10,000,000 species on Earth, how long will it take to destroy all of Earth's biodiversity?
between 300 and 500 years
