How often do our tectonic plates shift?



  1. 0 Votes

    Earth’s eight major (and many, many more minor) tectonic places shift only about two to four inches a year. Research shows that some plates are in a state of constant movement but shift so slowly that it’s barely noticeable. Due to their lower density, they are able to float above a layer of the Earth’s crust called the asthenosphere, occasionally causing earthquakes and volcanoes and even building mountains.
