Question
1) How are active continental margins related to plate tectonics?
e)Active continental margins are located along convergent plate boundaries, where oceanic lithosphere subducts beneath the edge of the continent.
2) Which of the following best explains the formation of the four terrestrial (inner) planets?
a)Active continental margins are associated with divergent boundaries, where new lithosphere is created and added both to the continental crust and the seafloor. b)Active continental boundaries are the starting points of the creation of new ocean basins. c)Active continental margins are located along convergent plate boundaries, where continental lithosphere subducts beneath the edge of the oceanic plate. d)Active continental margins commonly have submarine canyons where oceanic lithosphere subducts.e)Active continental margins are located along convergent plate boundaries, where oceanic lithosphere subducts beneath the edge of the continent.
2) Which of the following best explains the formation of the four terrestrial (inner) planets?
a)The terrestrial planets are former moons of the Jovian (outer) planets. b)The terrestrial planets formed from the repeated collision of icy comets. c)The terrestrial planets were initially part of a much larger planet that broke into smaller pieces. d)The terrestrial planets formed from the repeated collision and accretion of planetesimals. e)The terrestrial planets were pirated by the Sun from a nearby star.Explanation / Answer
1) e. Active continental margins are located along convergent plate boundaries, where oceanic lithosphere subducts beneath the edge of the continent.
Note: The oceanic lithosphere subducts beneath the leading edge of the continent.Ocean trences which are deep are formed will form at the convergent plate boundaries.
