Aquifer vs. Aqueduct — What's the Difference?

An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt). Groundwater from aquifers can be extracted using a water well.

A pipe or channel designed to transport water from a remote source, usually by gravity.

An underground layer of permeable rock, sediment, or soil that yields water. Aquifers can range from a few square kilometers to thousands of square kilometers in size.

A bridgelike structure supporting a conduit or canal passing over a river or low ground.

An underground layer of water-bearing porous stone, earth, or gravel.

(Anatomy)A channel or passage in an organ or a body part, especially such a channel for conveying fluid.

An underground bed or layer yielding ground water for wells and springs etc.; as, the Oglala aquifer. The water contained in an aquifer may be of great age, and in such cases is sometimes called fossil water.

An artificial channel that is constructed to convey water from one location to another.

Underground bed or layer yielding ground water for wells and springs etc

A structure carrying water over a river or depression, especially in regards to ancient aqueducts.

(anatomy) A structure conveying fluid, such as the cerebral aqueduct or vestibular aqueduct.

A conductor, conduit, or artificial channel for conveying water, especially one for supplying large cities with water.

A canal or passage; as, the aqueduct of Sylvius, a channel connecting the third and fourth ventricles of the brain.

A conduit that resembles a bridge but carries water over a valley
