apesWhich of the following shows the approximate concentration of CO2, N2, and O2 in dry air? - correct answer CO2<1% , N2 78% , O2 21% Which of the following is true about the region of Earth's atmosphere known as the stratosphere? - correct answer the highest concentration of naturally occurring ozone form in this layer Which of the following is the correct order of soil particles in order of increasing size? - correct answer sand - silt - clay Which of the following factors is fundamentally responsible for seasons on Earth? - correct answer the tilt of Earth's axis of rotation Which of the following does NOT exert a major influence on Earth's overall climate? - correct answer the seasonal development of temperature inversions in geographical basins Which of the following should be included in a watershed map to best determine the non-point source of a pollutant, such as fertilizer, found in a river? - correct answer the land use upstream of the river and water quality indicators in streams that run downstream into the river Which of the following best describes why understanding a watershed and its boundaries is important in designing housing developments along a river? - correct answer surface water and stormwater runoff will drain downstream within the watershed boundaries, so it is important to understand the flow of water through the watershed The water-holding capacity of soil is LEAST likely to be affected by the addition of which of the following? - correct answer pesticide the Sun's radiation provides the energy for all of the following EXCEPT - correct answer plate tectonics the rapid rate of this process in tropical forests results in low-nutrient soils - correct answer decomposition the primary cause of Earths seasons is the - correct answer constant tilt of Earth's rotational axis with respect to the plane of its orbit around the Sun the most abundant gas in Earth's atmosphere is - correct answer nitrogen the most abundant element in Earth's atmosphere - correct answer nitrogen Hoover Dam is the largest dam in the United States, built on the Colorado River to supply hydroelectric power and flood control. Which of the following best describes a downstream environmental effect of Hoover Dam on the Colorado River watershed? - correct answer the damming of the Colorado River led to a change in stream flow, preventing river water and sediments from the delta area Which of the following is the most likely effect of a strong El Niño event on the weather patterns in the United States? - correct answer wetter weather and cooler than average temperatures in the southeastern states and warmer temperatures in the Pacific Northwest Students want to determine the impact of soil erosion from the development of new housing. They plan to measure the density of a species of algae growing along the bottom of a river that flows through their town. The town is built in a heavy forested area. but a large area of trees along the river was recently clear-cut to allow for the construction of a new housing development, which has caused exposed soil to wash into the river. The river flows north to south through the town and is still forested both up and downstream of the town. Which of the following explains the variable that would be the best for students to measure to determine the direct impact of soil erosion caused by the construction project on the river? - correct answer turbidity, because a decrease in water clarity would indicate an increase in soil erosion Students want to determine the impact of soil erosion from the development of new housing. They plan to measure the density of a species of algae growing along the bottom of a river that flows through their town. The town is built in a heavy forested area. but a large area of trees along the river was recently clear-cut to allow for the construction of a new housing development, which has caused exposed soil to wash into the river. The river flows north to south through the town and is still forested both up and downstream of the town. Which of the following is the dependent variable in the study? - correct answer the density of a species of algae growing along the bottom of the river Students want to determine the impact of soil erosion from the development of new housing. They plan to measure the density of a species of algae growing along the bottom of a river that flows through their town. The town is built in a heavy forested area. but a large area of trees along the river was recently clear-cut to allow for the construction of a new housing development, which has caused exposed soil to wash into the river. The river flows north to south through the town and is still forested both up and downstream of the town. Which of the following would be the best control sample for the study? - correct answer a sample of water collected just downstream of the northern forest Reasons that human populations historically have settled in floodplains include which of the following? I. the soil in floodplains is usually fertile II. the terrain in floodplains tend to be flat III. floodplains are closed to rivers for transportation - correct answer I, II, and III Of the following, which has the greatest permeability? - correct answer sand most volcanism in the world is associate with - correct answer plate boundaries the phenomenon causing global warming occurs primarily in this region of the atmosphere - correct answer troposphere the beneficial ozone layer is in this region of the atmosphere - correct answer stratosphere most oxygen is found in this layer of the atmosphere - correct answer troposphere
