Correct Answer - Option 3 : Solid granite rocks
Explanation:
Aquifuge:
- Aquifuge is neither porous, not permeable, these are not inter-connected opening, so it does not contain water and does not allow it to pass through it.
- A good example of it is a massive compact rock without any fracture.
Aquifer:
- An aquifer is a saturated formation of earth material from which water is yield in sufficient quantity, due to the high permeability of earth material.
- Unconsolidated deposits of sand and gravel are good for aquifer formation.
- Groundwater is generally extracted from aquifers, so it is of much importance to us.
-
These are generally of 3 types.
- Unconfined aquifer
- Confined aquifer
- Perched aquifer
Aquiclude:
- It contains a large amount of water in pores, but extraction of water is very difficult. It may be considered as close to water movement.
- A good example of aquiclude is clay.
Aquitard:
- Aquitard form by that material through which the only seepage is possible but extraction of water is not so easy as in aquifer.
- A good example of aquitard is silty clay material.
