A weak asthenosphere, or low-viscosity zone (LVZ), underlying Earth's lithosphere has played an important role in interpreting isostasy, postglacial rebound (PGR), and the seismic LVZ, as well as proposed mechanisms for continental drift, plate tectonics, and postseismic relaxation. Consideration of...
The upper part of the Earth's mantle. The asthenosphere lies beneath the lithosphere and consists of several hundred miles of partially molten rock. Because it is partially molten, seismic waves passing through this layer have slow velocities. Compareatmosphere,hydrosphere,lithosphere. ...

The asthenosphere is the layer below the lithosphere. In this layer, rocks are hot enough to slowly flow, but they stay solid because of the strong pressure from the rocks above. The movement of the rock in this layer pushes and pulls onto the lithosphere, causing it to break into plates...
along with the 10 million species of living things they contain. The biosphere recycles its air, water, organisms, and minerals constantly to maintain an amazingly balanced state; human beings should probably do their best to imitate it. Though the word has a new sound to it, it was first ...
They float on currents in the underlying asthenosphere based on heating and cooling patterns of magma. An analogy for tectonic plates is the pieces of a puzzle. The puzzle pieces fit together, and they can slide across the table. The different ways the pieces move are like the three types ...
Transform plate boundaries form due to the horizontal motion of tectonic plates, driven primarily by mantle convection. This motion occurs as the Earth's lithospheric plates move on the semi-fluid asthenosphere beneath them. Transform boundaries typically develop along fractures or faults in the Earth...
