<span>The correct answer is D, filtration of pollutants, which will filter out the pollutants from the air, and will not impact the aqautic life system. Waste products in water causes death of aquatic organisms, so as the disruption of water flow, and sedimentation increase, which causes water clogging. </span>
Density is related to weight and box measurements. Since the box is the same only factor changing the density of the box is the weight of what’s in it. Box with marbles has the greatest density
Answer:
Option (1)
Explanation:
Clay is the most porous but least permeable rock.
The porosity is defined as the property of the rock that allows the water to store in its pore spaces. In simple words, it is the measure of the pore spaces that are present in the rock. Whereas the permeability is the property that allows the fluid to pass through the cracks of the rocks and mixing up with the groundwater.
So, in the case of clay, the inter-granular spaces (pore spaces) between the rocks help in trapping the water in them, but they do not allow the water to transmit and get mix up with the groundwater. So, they are the best example of porous rocks.
Hence, the correct answer is option (1).
