APES Unit 4 MCQWhich of the following statements best describes the boundary between the two tectonic plates seen in the map? - correct answer The map illustrates a transform boundary, where tectonic plates slide past each other as the Pacific Plate moves northwest and the North American Plate moves southeast. The Atlantic Ocean is expanding as a result of plate tectonics. Which of the following explanations best identifies the type of plate boundary and processes occurring at the Mid-Atlantic Ridge, as shown in the diagram below? - correct answer A divergent plate boundary exists at the Mid-Atlantic Ridge where plates move away from one another, leading to seafloor spreading. The map above shows the locations of known volcanoes and earthquakes. Which of the following explains what is being illustrated in the enclosed area in the northwest portion of the map? - correct answer The enclosed area shows a hot spot in the middle of the Pacific Plate in the Hawaiian Islands. Which of the following would be most helpful to determine the soil texture of a sample? - correct answer A density gradient tube and a soil triangle Which of the following is the control group for this experiment? - correct answer Soil with no grass Which of the following is a dependent variable in the experiment? - correct answer Percent change in mass of the soil sample A group of students wanted to determine if soil texture can vary by location. Several students brought in a sample of soil from their backyards. Each student added their soil sample of equal mass to a jar with exactly the same amount of water, shook the contents so that all soil particles were suspended in the water, and left the jars covered overnight. The next morning, the soil particles had settled out into layers and students could determine the percentage of each type of particle. The results of their soil test are shown below. Which of the following describes the independent variable in this investigation? - correct answer Soil samples taken from different locations A group of students wanted to determine if soil texture can vary by location. Several students brought in a sample of soil from their backyards. Each student added their soil sample of equal mass to a jar with exactly the same amount of water, shook the contents so that all soil particles were suspended in the water, and left the jars covered overnight. The next morning, the soil particles had settled out into layers and students could determine the percentage of each type of particle. The results of their soil test are shown below. Which of the following describes the dependent variable in this investigation? - correct answer Percentage of each particle size in each soil sample A group of students wanted to determine if soil texture can vary by location. Several students brought in a sample of soil from their backyards. Each student added their soil sample of equal mass to a jar with exactly the same amount of water, shook the contents so that all soil particles were suspended in the water, and left the jars covered overnight. The next morning, the soil particles had settled out into layers and students could determine the percentage of each type of particle. The results of their soil test are shown below. A student claims that soil sample B would be classified as a loam. Which of the following best describes the method used by the student to reach this conclusion? - correct answer The student used a soil triangle to determine where the lines intersect for sand, silt, and clay for the soil sample. Which of the following abiotic factors, when graphed on the x-axis, leads to the curved line in the graph due to variation in the different layers of the atmosphere? - correct answer Temperature gradients The vast majority of ozone (O3) is found in a thin layer due to a lack of circulation in which of the following atmospheric layers? - correct answer Stratosphere Which of the following layers of the atmosphere contains charged gas molecules that glow and produce light when hit by solar energy, leading to glowing gases such as the northern lights, found over 90 kilometers above Earth's surface? - correct answer Thermosphere Which of the following combinations correctly identifies and explains the effects of the differences in the distribution of solar radiation on Earth as seen in the diagram above? - correct answer Global wind patterns are created because uneven solar radiation results in warm air at low latitudes and cool air at high latitudes, resulting in density differences between the air masses.
