If an area has very little permeability, such as a city where the ground is mostly concrete, what will happen to most of the rainwater?
A. It will become groundwater.
OB. It will be pumped into underground reservoirs by large machines.
C. It will become runoff.
D. The type of surface it falls on does not affect rainwater.


Sagot :

Answer:

C

Explanation:

The water won't be able to penetrate the ground so can't become ground water and reservoirs are usually above ground not underground so it will become run off.

Permeability is the ability of the substances to get diffused easily across the surface. The concrete ground results in the rainwater becoming runoff. Thus, option C is correct.

What is permeability?

Permeability is the capacity of the water or any fluid to pass and diffuse across the substances or any membrane to get from the higher to lower concentration.

The concrete ground and roads are not permeable and do not allow water to pass through the material and effects the collection of the rainwater through infiltration.

The rainwater is unable to filter into the groundwater and becomes runoff. This runoff gets accumulated on the roads and can even lead to floods and drain blockages.

Therefore, option C. the less permeable roads cause rainwater to become runoff.
