In short, an acid is a compound that can give up a hydrogen ion (a proton, H+) in solution. A base is a compound that can accept a proton. If you're looking at chemical equations, the acid will be the compound with more hydrogen atoms.Usually, an acid is positively charged.n short, an acid is a compound that can give up a hydrogen ion (a proton, H+) in solution.

The lithosphere is the brittle outer layer of the solid Earth. The plates of plate tectonics are segments of the lithosphere. Its top is easy to see -- it's at the Earth's surface -- but the base of the lithosphere is in a transition, which is an active area of research.
Plate tectonic theory. is based on the model that the lithosphere is rigid and consists of both oceanic crust (up to 100 km thick) continental crust (up to 250 km thick) The lithosphere consists of plates that move as a unit.hy do most lithospheric plates contain portions of oceanic crust and continental crust. New oceanic crust is created when continental crust rifts apart. New oceanic crust is created when continental crust rifts apart; as a result, most lithospheric plates possess both types.
