The lithosphere and asthenosphere are the upper two layers of the Earth. Though they ... Both the names, lithosphere and asthenosphere, have origins in the Greek language. ... Often, when large tectonic plates either collide or move beneath or above each other, it results in large-scale earthquakes and even volcanoes.

Aug 31, 2016 ... Layers of Differing Physical Properties. Lithosphere - about 100 km thick (up to 200 km thick beneath continents), very brittle, easily fractures at low temperature. Asthenosphere - about 250 km thick - solid rock, but soft and flows easily (ductile) . Mesosphere - about 2500 km thick, solid rock, but still capable ...
It is commonly compared to the skin of an apple, whereas the apple represents the earth. The temperature of the crust varies from the air on top, to upward of 1600 at the deepest parts. The tectonic plates are part of the crust of the earth, moving and shifting on the softer mantle or asthenosphere below. Occasionally the ...
Apr 7, 2014 ... At the pressures and temperatures expected at the LAB beneath continents, alkali basalt melts but doesn't sink into the asthenosphere or rise into the lithosphere -- it's neutrally buoyant and could remain stable at the LAB, the team writes in Earth and Planetary Science Letters, which published their results.

Lithosphere is cold, solid and rigid whereas as Asthenosphere is partially molten. The lithosphere is broken up into large solid plates called tectonic plates. These tectonic plates move around which are the basis of plate tectonics. How many miles deep is the lithosphere? The lithosphere is about 40 - 250 miles deep or 60 ...
In Geosphere is the solid or mineral part of the Earth, consists of layers, from the outer crust down to the inner core, which have separated through density and ... of the geosphere - chemically, into crust, mantle, and core, or functionally, in the case of the outer layers (crust and mantle) into lithosphere and asthenosphere.
