#civilservices #geology #csirnet #geography #geotectonics • Concept of Lithosphere and Asthenosphere • • The lithosphere (lithos = rock)—Earth’s cool, rigid outer layer—is 70–200 kilometers (44–125 miles) in thickness. It is composed of the continental and oceanic crusts and the uppermost cool and rigid portion of the mantle. • • The asthenosphere (asthenes = weak) is the hot, partially melted, slowly flowing layer of upper mantle below the lithosphere extending to a depth of about 350–650 kilometers (220–400 miles). • • https://t.me/+VOV8D-rq687H0dRr Telegram
