What most likely happens if water flows through a permeable soil layer and reaches a clay layer?

It dries up.

It soaks in

It pools on top of the clay layer.

It flows down through the clay layer

The correct answer is C. It pools on top of the clay layer

Explanation:

A soil layer is permeable if it allows liquids to pass through it, this is a common property in most superficial layers of the soil and layers composed of materials such as sand. In the case of clay, this has a low permeability, which implies water and other liquids cannot easily pass through this layer. This causes water to accumulate between clay and the previous layer; according to this, in the case presented water will pool on top of the clay layer.
