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.
Oceanic plates are where there is tectonic plates that are dencer than continental tectonic plate(s). Oceanic plates are mainly found at destrictive plate margins because the oceanic plate subducts (goes under) the continental plate.ontinental plates. Continental plates are where there is tectonic plate that are lighter than oceanic tectonic plate(s). Continental plates are mainly found at destrictive plate margins because the continental plate rises above the oceanic plate.
