The hawaiian islands formed as a result of tectonic plate movement over a volcanic hot spot. the rate of plate movement can be calculated by dividing the distance that an island is from the hot spot by the age of the island. a scientist determines that one of the islands is 4860 kilometers from the hot spot and is 6.5×10^7 years old. which of the following statements are true? select three that apply. a the rate of plate movement is approximately 7.5 cm per year. b the rate of plate movement is approximately 7.5×10^-5km per year. c in a million years, the plate has moved a distance of approximately 75 m. d in a million years, the plate has moved a distance of approximately 7.5×10^7 mm.
