A meniscus.
A meniscus.
The upper surface of the liquid in a graduated cylinder is called the meniscus. It appears curved due to surface tension, and the measurement should be read at the bottom of the meniscus for an accurate volume reading.
The curved surface at the top of a liquid in a container is called the meniscus. When measuring a liquid in a container, it's important to read the measurement at the bottom of the meniscus to ensure an accurate reading.

The free surface of a liquid is the upper boundary of the liquid where it meets the air or another medium. It is the surface that is not confined by a container and is therefore free to move and change shape in response to external forces, such as gravity.
The upper surface of water is called the water's surface or water level. It is the boundary where the water meets the air above it.
At the surface of the liquid the phenomenon is called evaporation. In the entire voume of the liquid the phenomenon is called vaporization.
Evaporation. It only happens at the surface of a liquid.
It is called a MENISCUS caused by capillary action betweem the molecules of the liquid and the molecules of the container, and resulting from surface tension within the liquid. In addition: Adhesion: Making one material adhere to another.
The upper surface of groundwater is called the unsaturated zone. The unsaturated upper surface contains water, as well as spaces of air, particle grains and rocks.
