APES Unit 4 Review - MRQ 2022/2023_ Answers Highlighted Which of the following statements best describes the boundary between the two tectonic plates: the Relative motion of the North American & the Pacific Plate? (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 San Andreas Fault is a transform boundary. The plates slide past each other in opposite directions, which can result in an earthquake.) 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? (Correct Answer) - A divergent plate boundary exists at the MidAtlantic Ridge where plates move away from one another, leading to seafloor spreading. (The Atlantic Ocean is expanding east to west at a rate of about 2.5 centimeters annually. Divergent plate boundaries are the only type of boundary that results in seafloor spreading.) A map shows 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.
