the process by which water is transferred from the land to the atmosphere by evaporation from the soil and other surfaces and by transpiration from plants.

the combined mass of water found on, under, and above the surface of a planet, minor planet or natural satellite.

the lower layer of water in a stratified lake, typically cooler than the water above and relatively stagnant.

the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane

a scale used to specify how acidic or basic (or alkaline) a water-based solution is. Acidic solutions have a lower pH, while basic solutions have a higher pH.

water released from clouds in the form of rain, freezing rain, sleet, snow, or hail.

the draining away of water (or substances carried in it) from the surface of an area

the saltiness or amount of salt dissolved in a body of water.

a physical property equal to the amount of force per unit area necessary to expand the surface of a liquid.

when an appreciable temperature difference exists between the two layers, they do not mix, but behave independently and have very different chemical and biological properties

a steep temperature gradient in a body of water such as a lake, marked by a layer above and below which the water is at different temperatures.

the process in which some water within plants evaporates into the atmosphere
