APES Unit 4 progress check: mcq beep-beep correctly answered rated A+

APES Unit 4 progress check: mcq beep-beep correctly answered rated A+Which 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 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? - correct answer Soil 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? - correct answer Percent change in mass of the soil sample
