Plate Tectonics
... To calculate the rate of plate motion, divide the distance the plate moves by the time it takes to move that distance. Rate = distance/time For example, a plate takes two million years to move 156 km. Calculate its rate of motion. 156 km/2,000,000 years = 7.8 cm per year Practice Problem The Pacific ...
