The Water Cycle

This is what it means rain, sleet, hail, snow and other forms of water falling from the sky.

Runoff

is the water flow which occurs when soil is infiltrated to full capacity and excess water, from rain, snowmelt, or other sources flows over the land. This is a major component of the water cycle.[1][2] Runoff that occurs on surfaces before reaching a channel is also called a nonpoint source. If a nonpoint source contains man-made contaminants, the runoff is called nonpoint source pollution. A land area which produces runoff draining to common point is called a watershed. When runoff flows along the ground, it can pick up soil contaminants such as petroleum, pesticides (in particular herbicides and insecticides), or fertilizers that become discharge or nonpoint source pollution

• In physics, chemistry and materials science, percolation concerns the movement and filtering of fluids through porous materials. Examples include the movement of solvents through filter paper (chromatography) and the movement of petroleum through fractured rock.

• Evaporation is the slow vaporization of a liquid and the reverse of condensation. A type of phase transition, it is the process by which molecules in a liquid state (e.g. water) spontaneously become gaseous (e.g. water vapor). Generally, evaporation can be seen by the gradual disappearance of a liquid from a substance when exposed to a significant volume of gas

evaporation of water from the aerial parts of plants, especially leaves but also stems, flowers and roots. Leaf surfaces are dotted with openings called stoma that are bordered by guard cells.

Condensation is the change of the physical state of aggregation (or simply state) of matter from gaseous phase into liquid phase.[1] When the transition happens from the gaseous phase into the solid phase directly, bypassing the liquid phase the change is called deposition, which is the opposite of sublimation.Condensation commonly occurs when a vapor is cooled to its dew point, but the dewpoint can also be reached through compression. The condensed vapor is called a condensate, the laboratory or the industrial equipment used for condensation is called a condenser.The science of studying the thermodynamic properties of moist air and the interrelationships between these in order to analyze, and predict properties by changing in the conditions of moist air is called psychrometry. The interrelationship can be graphically represented, and prediction carried out graphically by the psychrometric chart Most people think the water is condensation, but condensation is only the process of change.Water vapor that naturally condenses on cold surfaces into liquid water is called dew. Water vapor will only condense onto another surface when the temperature of that surface is cooler than the temperature of the water vapor. The water molecule brings a parcel of heat with it. In order to have condensed, the molecule tranfers its kinetic energy to the atmosphere. When water vapor condenses into liquid water, the hydrogen bonds form again and release latent heat, which increases the sensible heat and causes the air temperature to rise. Sensible heat is removed from the air and the temperature drops when evaporation is occurring and latent heat is converted to sensible heat and the temperature rises when condensation occurs.
