15.1: Plate Tectonics and Continental Drift - Geosciences LibreTexts
WebTectonic plates do float on the molten interior of the Earth; rather, the motion of lithospheric plates moving across the ductile, more viscous asthenosphere causes plate tectonics. Teachers should clarify that tectonic plates don’t float because the asthenosphere is not liquid. Intended Audience. Educator. Educational Level. Web1. Introduce students to the concept of continental movement and plate tectonics. Call on volunteers to tell what they know about plate tectonics. Display a globe or world map. … WebPLATES AND PLATE MOTION By the late 1960’s, the ideas of continental drift and sea floor spreading had been combined into the theory of plate tectonics. A plate is a large, mobile slab of rock that is part of the Earth’s surface. The surface of a plate may be composed entirely of sea floor (the Nazca Plate) or it may be made up tarun mahadevan
