Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Well sorted soil ____
A
has low porosity
B
has low pore space
C
has high porosity
D
means water will move through slowly
Explanation: 

Detailed explanation-1: -Thus, well sorted sediments have higher porosity while poorly sorted sediments have low porosity. Permeability refers to how easily water passes through sediments and rock. Permeability is a function of the size of pore openings.

Detailed explanation-2: -Well-sorted sediments (i.e., uniform grain size) have higher porosity, because smaller sediment particles do not fill in the spaces between the larger particles.

Detailed explanation-3: -Clay is the most porous sediment but is the least permeable. Clay usually acts as an aquitard, impeding the flow of water.

Detailed explanation-4: -Well sorted gravel and sands had high porosity and also had high permeability. There was an exception to the above mentioned correlation-clay / silt can have high porosity because these small soil particles have a greater surface area, therefore, more water can remain in the soil.

Detailed explanation-5: -According to the above plot, the well-sorted rock has the lowest permeability, while poor and fair-sorted rock has the highest permeability.
