What is a meniscus? A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material. With water, you can think of it as when water sticks to the inside of a glass. Adhesion is responsible for a meniscus and this has to do in part with water's fairly high surface tension.
Meniscus is the curve of the upper surface in any liquid. It can be convex with is the curving outward or bulge outward. Concave is just the opposite. Cohesion is the ability of water molecules to cling to each other because of hydrogen bonds. Adhesion is the ability of water to cling to other polar surfaces, a result of water's polarity.
