Soil materials which have the property to store water due to good number of pores in them, but passage of water through them is not possible, are called :
- AAquifuge
- BAquicludeCorrect
- CAquitard
- DAquifer
Solution
Concept
Aquiclude
Step-by-step solution
1. Aquiclude: stores water in its pores but cannot transmit it (e.g. clay). 2. Aquifuge: neither stores nor transmits water. 3. Aquitard: transmits water very slowly. 4. Aquifer: stores and transmits water in useful quantity.
Explanation
Clay is porous and saturated with water, but its pores are so small that water cannot move through it. Such a formation is called an aquiclude.
Why the other options are wrong
An aquifuge has no pores for water. An aquitard allows very slow flow. An aquifer transmits water freely.
Shortcut
Aqui-clude = closed: holds but doesn't release.
Common mistake
Choosing aquifuge.
Correct answer: B) Aquiclude
