Check the box next to the seafloor age map folder to view the ages of the oceanic crust around the world. note that you can select the folder and use the transparency slider at the bottom of the places panel to make the items in this folder semi-transparent. turn on the tectonic plates folder (divergent = red, convergent - green, and transform = light blue). also, in the layers panel, turn on borders and labels and gallery > volcanoes. oceanic hot spots - hawaiian island-emperor seamount chain. make the seafloor age map semi-transparent, and turn on the hawaiian island-emperor seamount chain folder to show their age of formation in millions of years (ma). use the ruler tool to measure the distance between midway atoll and kilauea (cm; problem 19 placemarks) and calculate the average velocity of the pacific plate in cm per year. select one a.1.9 cm per year b. -4.2 cm per year oc -8.8 cm per year od 15 cm per year a020) oceanic hot spots - hawaiian island-emperor seamount chain. what is the approximate age of the bend in the hawaiian island-emperor seamount hot-spot chain (should you use the age of the volcanic features or the age of the seafloor)? select one: o a. 125 ma o b. 150 ma oc. 32 ma d. -43 ma a021) check the box next to the yellowstone hot-spot trail folder to view the locations and ages of the main calderas that formed in association with the yellowstone continental hot spot over the past 16.5 ma. note that you can select the folder and use the transparency slider at the bottom of the places panel to make the items in this folder semi-transparent. continental hot spots - yellowstone hot-spot trail. use the path tab on the ruler tool to measure the distance between the problem 21 placemarks (cm) along the hot-spot trail. calculate the average velocity of the north american plate in cm per year using 16.5 ma and 0.63 ma for the two placemarks. select one: a.1.9 cm per year b. ^4.2 cm per year c.-8.8 cm per year d. "15 cm per year a022) continental hot spots - hawaiian island-emperor seamount chain & yellowstone hot-spot trail. which of the following best describes the present-day direction and rate of motion of both the pacific plate and the north american plate (refer to problems 19 & 21)? think about the analogy of a piece of paper passing over a candle. select one: o a. pacific plate moves se at about half the rate of the ne-moving north american plate o b. pacific plate moves nw at about the same rate of the ne-moving north american plate c. pacific plate moves se at about twice the rate of the sw-moving north american plate d. pacific plate moves nw at about twice the rate of the sw-moving north american plate
