|lithosphere vs asthenosphere||1.73||0.7||6850||55|
The Lithosphere is composed of the crust and upper most solid mantle . While the Asthenosphere, which lies beneath the lithosphere, is composed of the upper most weaker part of the mantle. As we move from the lithosphere to the asthenosphere the temperature increases.What are the theories of lithosphere?
According to Plate tectonics theory - the lithosphere is believed to have been broken into fragments that are floating on a ductile layer called asthenosphere (upper part of the mantle). The movement of these plates is attributed to the convention currents being generated in the upper mantle. Plates move horizontally over the asthenosphere as rigid units. More items...
