This natural reservoir is often located in areas of high altitude and high latitude. Water is stored in a solid form.

This natural reservoir is located under the earth's surface. Water reaches this area through percolation.

A natural reservoir that is made of water in it's gaseous form. Water is transferred to this zone using evaporation.

This natural reservoir is a stagnant body of open water often formed in a depression in the land.

This natural reservoir is categorized by a constant downhill flow.

Man-made Lake

This man made reservoir is in areas without easy access to water.

Water movement through a plant from the soil to it's aerial parts such as the leaves and stems.

Natural examples of this include snowmelt, soil erosion, etc.

Examples of this include pipes from sewage plants, gasoline spills and contribute greatly to water pollution.

Process when water enters the ground but does not go all the way through, making the soil moist.

Process when water travels through the ground that leads to groundwater reserves.

The result of this is saltwater intrusion, which can contaminate fresh drinking water.

Movement of saline waters into freshwater aquifers.

Process when groundwater exits the ground.

Natural process when water goes straight from a solid to gas state.

Natural process that changes water from liquid to gas.

Process when water vapor becomes a liquid.

Any liquid or solid form of water that forms in the atmosphere and falls back to earth.

Contamination of water bodies with harmful substances.

Things such as deforestation filling wetlands increase this.

Increased erosion and runoff on land with buildings and pavements.

When mismanaged, this process of creating energy can lead to droughts downstream.

This human made process can cause leaching and runoffs in the area where the water was extracted.
