When water is flowing through some confined aquifer, the spring formed is known as:a)Surface Springb)Artesian Springc)Unconfined Springd)Gravity SpringCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

An Artesian spring is defined as, a spring, the water from which issues under artesian pressure, generally through some fissure or other opening in the confining bed that overlies the aquifer.
An Artesian spring is at a higher elevation than the groundwater that feeds it, and the water is under pressure, which allows it to flow. A regular spring can be thought of as a gravity spring and is at a lower or equal elevation as groundwater with water flowing naturally downgradient to the spring.

Answer

Artesian Spring
An artesian spring is formed when water from a confined aquifer flows out of the ground under its own pressure. This type of spring occurs when a layer of impermeable rock lies above the aquifer, creating a natural pressure system that causes the water to rise to the surface without the need for pumping.

Characteristics of an Artesian Spring
- Artesian springs typically flow continuously and are known for their steady water supply.
- The water from an artesian spring is often clean and pure, as it has been naturally filtered through the layers of rock in the aquifer.
- These springs can be found in various locations around the world, often in areas where there is significant geological activity.

How Artesian Springs are Different
- Artesian springs are distinct from unconfined springs, which are not under pressure and flow freely from the ground.
- Unlike gravity springs, where water flows downward due to gravity, artesian springs flow upward due to the pressure within the confined aquifer.
- Surface springs, on the other hand, are typically found in areas where the water table is close to the surface and may dry up during periods of drought.
In conclusion, an artesian spring is a unique natural phenomenon that results from the specific geological conditions of a confined aquifer. The pressure within the aquifer causes the water to flow upward, creating a reliable source of clean water for various purposes.
