Question

When precipitation falls on land surfaces, it begins to flow toward sea level. The water is more likely to flow toward sea level as groundwater if A. the surface is not porous and there are few interconnected spaces underground. B. the surface is porous and there are few interconnected spaces underground. C. the surface is not porous and there are lots of interconnected spaces underground. D. the surface is porous and there are lots of interconnected spaces underground.

Answer 1

The answer is; D

If the ground is porous, the water from precipitation is able to permeate into the ground to the water table. If there are interconnected spaces in the underground, the underground water is able to flow slowly and steadily beneath the ground until it gets to sea level.  

Answer 2

Answer:

Option (D)

Explanation:

The porosity refers to the property of the rock by which the pore spaces in the rocks has the ability to store water and air in them. The value of this porosity ranges from 0 to 1. This property plays an important role in the water cycle. For example, Clay, which is the most permeable.

The permeability of a rock is defined as the property by which the water is allowed to pass through the pore spaces (interconnected spaces) and gets mix up with the groundwater. For example, Gravel having the highest permeability. It also plays a significant role in the water cycle.

During precipitation, some of the water when flows over the land, they get percolated into the ground. This water can infiltrate into the ground where the rocks are more porous and permeable. The higher the porosity and permeability of the rock, the higher is the rate of infiltration.

This percolating water gets mixed up with the groundwater and it eventually gets added to the seas.

Thus, the correct answer is option (D).
