Why is the unsaturated zone not filled with water

The unsaturated zone is also called as vedose zone. It is a zone that lies above the ground water table. It includes the subsurface layers of soil. ... Hence, this can be said that unsaturated zone is not filled by water because it is permeable and water flows through it.

Explanation:

The answer is (D) It is permeable and water flows through it. I took the test and the answer was (D).

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

increased stability in the completion of fluorine's outer shell.
