compare and contrast earths lithosphere and asthenosphere?

The lithosphere (litho:rock; sphere:layer) is the strong, upper 100 km of the Earth.

The lithosphere is the tectonic plate we talk about in plate tectonics. The

asthenosphere (a:without; stheno:strength) is the weak and easily deformed layer of

the Earth that acts as a "lubricant" for the tectonic plates to slide over. The

asthenosphere extends from 100 km depth to 660 km beneath the Earth's surface.

Beneath the asthenosphere is the mesosphere, another strong layer.

The field of geochemistry involves study of the chemical composition of the Earth and other planets, chemical processes and reactions that govern the composition of rocks and soils, and the cycles of matter and energy that transport the Earth's chemical components in time and space, and their interaction with the hydrosphere and the atmosphere.
