Question
Consider the following statements regarding artesian aquifer :
- It is a confined aquifer containing groundwater under negative pressure.
- It is a geologic layer of porous, but impermeable material such as sand and gravel, limestone or sandstone.
- The Great Artesian basin is the largest and deepest artesian basin in the world.
Answer: Option C
Answer: (c)An Artesian aquifer is a confined aquifer containing groundwater under positive pressure. This causes the water level in a well to rise to a point, where hydro-static equilibrium has been reached. This type of well is called an Artesian well.Water may even reach the ground surface if the natural pressure is high enough, in which case the well is called a flowing Artesian well.
