Continents on the Move

This resource presents information about the use of satellites and laser beams to measure the movement of continents in order to confirm the Theory of Plate Tectonics. It explains that observatories are established on two continents and that by knowing the fixed location of the satellite, scientists can calculate the travel time of the laser beam to each observatory and triangulate to arrive at the distance between the observatories. They can then compare the most recent distance to the distance from a year before, and calculate how far the continents have moved during that time Educational levels: High school, Middle school
