At places the groundwater is stored between layers of hard rock below the water table. This is known as _____.

The correct answer is an aquifer

Key Points:

• An aquifer is an underground layer of porous rocks or permeable rocks that store and retain groundwater levels in the soil.
• The underground aquifer is built with all types of porous or permeable rock materials, such as sand, gravel, or silt, making it a suitable water absorber.
• The rainwater enters the aquifer through the soil and becomes a part of the groundwater.
• The groundwater from the aquifers then resurfaces from springs and wells.
• We can also extract the aquifer water with the help of a water well.
• The study of groundwater, aquifer, and their property is known as hydrogeology.

Additional Information:Pond:

• A pond is an area filled with water, either natural or artificial, that's lower than a lake.
• Defining them to be lower than 5 hectares (12 acres) in area, lower than 5 measures (16 ft) deep, and with lower than 30 emergent foliage helps in distinguishing their ecology from that of lakes and washes.

Lake:

• A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake.

Well:

• A well is an excavation or structure created in the ground by digging, driving, or drilling to access liquid resources, usually water.
