When plates move they sometimes open small cracks that release heat from under earths plate, coming from the mantle or even the core at times, this heat allows scientists to determine where the plates are moving from and where they are moving to.
the plates from sink go to hot water then =clean ;
Hot spots are stationary areas of volcanic activity that form as tectonic plates move over them. Geologists track plate motion by studying the age and distribution of volcanoes created by these hot spots, such as those in the Hawaiian Islands. This method offers insights into both the direction and rate of tectonic plate movement over time.
