8 Facts You Need to Know About Tectonic Plates

Plate tectonics came to be generally accepted by geoscientists after seafloor spreading was validated in the mid to late 1960s. Earth's lithosphere, which is the rigid outermost shell of the planet (the crust and upper mantle), is broken into seven or eight major plates (depending on how they are defined) and many … Se mer Plate tectonics (from the Late Latin: tectonicus, from the Ancient Greek: τεκτονικός, lit. 'pertaining to building') is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of … Se mer It has generally been accepted that tectonic plates are able to move because of the relative density of oceanic lithosphere and the relative weakness of the asthenosphere. Dissipation of heat from the mantle is acknowledged to be the original source of the … Se mer Continental drift theory helps biogeographers to explain the disjunct biogeographic distribution of present-day life found on different continents but having Se mer The outer layers of Earth are divided into the lithosphere and asthenosphere.
