Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The water is able to flow the pore spaces, what type of rock is it?
A
permeable
B
impermeable
C
aquifer
D
geyser
Explanation: 

Detailed explanation-1: -An aquifer is defined as a body of rock or unconsolidated sediment that has sufficient permeability to allow water to flow through it.

Detailed explanation-2: -Gravel and sand are both porous and permeable, making them good aquifer materials. Gravel has the highest permeability.

Detailed explanation-3: -Permeability is the ability of fluids to flow through rock. It depends on the connectivity of the pore space. Permeable rocks include sandstone and fractured igneous and metamorphic rocks and karst limestone. Impermeable rocks include shales and unfractured igneous and metamorphic rocks.

Detailed explanation-4: -Porous and permeable materials include soil (if not too clay rich), sand, sandstone, limestone, fractured igneous and metamorphic rock, vesicular basalt and scoria. Impermeable and/or non-porous materials include clay, shale, non-fractured igneous and metamorphic rocks.

Detailed explanation-5: -For a rock to be permeable and for water to move through it, the pore spaces between the grains in the rock must be connected. Permeability is therefore a measure of the ability of water to move through a rock.
