The word for this is meniscus. It comes from a Greek word meaning "crescent". It takes that shape due to surface tension.
The weight of the liquid is, plus possibly the atmospheric pressure on the top surface of the liquid.
More curved surfaces will change the angle of refraction when compared to a less curved surface, independent of the angle of the light source.
An air foil has a flat path underneath and a curved surface over the top. the air travelling over the curved surface travels slower as it has further to go than the same air underneath. this has the effect of causing a vacuum and therefore lift.
Bernoulli showed (using water models) how flow over an airfoil (the top surface curved more than the bottom = shape of aircraft wing) lowered the pressure on the top surface, thus producing lift.
Mercury is the liquid with the strongest surface tension.

The curved upper surface of a column of liquid is called a "meniscus".
