Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which describes materials that have large and connected pores, such as sand and gravel?
A
unsaturated
B
impermeable
C
saturated
D
permeable
Explanation: 

Detailed explanation-1: -Permeable material contains interconnected cracks or spaces that are both numerous enough and large enough to allow water to move freely.

Detailed explanation-2: -A permeable material has a greater number of larger, well-connected pores spaces, whereas an impermeable material has fewer, smaller pores that are poorly connected.

Detailed explanation-3: -An aquifer is an underground layer of a water-bearing stratum of permeable rock, sand, or gravel that contains water or allows water to pass through it. Aquifers may be found in any geological formation containing or conducting ground water, especially one that supplies the water for wells, springs, etc.

Detailed explanation-4: -Some rocks have large pores that are interconnected, and such rocks are permeable because water can easily move through the layers. If the pores are larger, they are more interconnected, which means that greater porosity is also greater permeability.

Detailed explanation-5: -Permeable means the voids are connected so water can pass through. Porous and permeable materials include soil (if not too clay rich), sand, sandstone, limestone, fractured igneous and metamorphic rock, vesicular basalt and scoria.
