Why do lithospheric plates move? Socratic

WebIn zones of convergence, where two plates are moving toward each other, asthenospheric materials may also be exposed to increased pressure and begin to flow downward. In this case, the lighter of the colliding plates slides upward and over the heavier of the plates, which dives down into the asthenosphere. WebJul 18, 2013 · They drift because they are sitting on a layer of solid rock (the upper mantle or "asthenosphere") that is weak and ductile enough that it can flow very slowly under heat convection, somewhat like a liquid. Under the continents is a layer of solid rock known as the upper mantle or asthenosphere.

WebYes, the Atlantic ocean is getting bigger and the pacific ocean is getting smaller due to the continental drift. This is caused by the natural moments of the plates as they glide on the semi-liquid mantle. This mantle often has currents caused by the subducting fluid and this force pushed the plates in many directions. Comment ( 2 votes) Upvote WebJul 7, 2024 · Asthenosphere –The asthenosphere is made of very viscous, ductile, semi-solid material on which the lithosphere moves. It is a solid that can behave like a liquid, and it is about 440km thick. Where is asthenosphere found? Asthenosphere is found in the mantle at a depth of 100-250 km. It is found in the semi liquid state.
