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.
Report Abuse. The lithosphere (from the Greek for rocky sphere) is the solid outermost shell of a rocky planet. On the Earth, the lithosphere includes the crust and the uppermost layer of the mantle (the upper mantle or lower lithosphere) which is joined to the crust. As the cooling surface layer of the Earth's convection system, the lithosphere thickens over time.
