WebIts thickness ranges from 40 to 280 km [ 35 ]. The lithosphere is not continuous. It is broken into segments called plates. A plate boundary is where two plates meet and move relative to each other. Plate boundaries are where we see plate tectonics in action—mountain building, triggering earthquakes, and generating volcanic activity. Asthenosphere WebEarth's lithosphere, which constitutes the hard and rigid outer vertical layer of the Earth, includes the crust and the uppermost mantle. The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle. The lithosphere–asthenosphere boundary is defined by a difference in response to stress.

It lies between about 100 kilometers (62 miles) and 410 kilometers (255 miles) … WebThis strong outer layer is called the lithosphere, which is 100 km (60 miles) thick. The lithosphere includes the crust and upper mantle. Below the lithosphere is the asthenosphere, which is a plastic like layer that allow the lithosphere to move around due to its convection currents. chippewa homestead boots
