APES Unit 4 progress check: mcq Questions & Answers

Which of the following statements best describes the boundary between the two tectonic plates seen in the map? - ANSWERSThe 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? - ANSWERSA 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? - ANSWERSThe 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? - ANSWERSA density gradient tube and a soil triangle Students want to determine how vegetation affects soil erosion. They collect four soil samples of equal starting mass with different types of vegetative cover, as seen in the table below. Each sample is placed in a three-sided plastic dish that can drain into a beaker and is exposed to the same amount of consistent, steady rainfall for ten minutes. The water and soil runoff are collected in the beaker and separated. The average values for each sample are provided below. Which of the following is the control group for this experiment? - ANSWERSSoil with no grass Students want to determine how vegetation affects soil erosion. They collect four soil samples of equal starting mass with different types of vegetative cover, as seen in the table below. Each sample is placed in a three-sided plastic dish that can drain into a beaker and is exposed to the same amount of consistent, steady rainfall for ten minutes. The water and soil runoff are collected in the beaker and separated. The average values for each sample are provided below.Which of the following is a dependent variable in the experiment? - ANSWERSPercent change in mass of the soil sample Which of the following describes the independent variable in this investigation? - ANSWERSSoil samples taken from different locations Which of the following describes the dependent variable in this investigation? - ANSWERSPercentage of each particle size in each soil sample 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? - ANSWERSThe 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? - ANSWERSTemperature 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? - ANSWERSStratosphere 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? - ANSWERSThermosphere 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? - ANSWERSGlobal 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. Which of the following is the best explanation for the formation of Hadley cells in the tropics, as seen in the diagram, between 30°Nand 30°S latitude? - ANSWERSThe Sun warms the moist air at the equator and causes it to rise because of its lower density. As the warm air moves away from the equator, it cools, becomes denser, and then sinks. Which of the following is the best explanation for the deflection of the trade winds in both hemispheres, as seen in the diagram above? - ANSWERSThe wind is deflected west because of Earth's rotation. The Mississippi watershed is the largest in North America, draining all or part of thirty-two states in the United States and two Canadian provinces. A new apartment complex is being built on a steep slope near the source of the Mississippi River outside of Minneapolis, Minnesota. Which of the following measures should be taken to best reduce erosion at the construction site to protect the Mississippi watershed? - ANSWERSPlant grass and shrubs on the slope. A developer wants to develop a large tract of land near a watershed, which will require the removal of several large trees. Which of the following statements best describes the impact that the development would have on the watershed? - ANSWERSRemoving large trees would cause an increase in temperature and keep the surrounding water and soil warmer.
