<span><span>Porosity is the amount of empty space in a rock or other earth material (like sand) - in other words, it's how much water a material can hold.
Permeability refers to how well water flows through a material - the flow is controlled by how large the pores are and how well connected the pores are in a given object.</span><span>Therefore, there these are two primary factors that limit the movement and the amount of water (or other fluids) retained in rocks/sedimentary materials.</span></span>

Answer:
The correct answer is D. The deepest parts of the oceans, located near the continents, are the oceanic trenches.
Explanation:
The ocean trenches are large depressions at the base of the seabed, which constitute the deepest parts of the Earth. Of these, the Mariana Trench, located in the Pacific Ocean to the east of China, is the deepest, being approximately 11,000 meters deep.
These trenches are formed by the activity of tectonic plates, specifically when one plate moves below the other and by the force exerted a depression is generated in the seabed, followed by a chain of volcanic islands at a close distance.
