Answer: The correct options are:
<em>exerts more pressure as it increases
</em>
<em>measures how tightly molecules are packed
</em>
<em>equals mass divided by volume</em>
Explanation:
Air density can be described as mass per unit of volume of the volume of air.
As the altitude increases, the air density tens to decrease. Hence, option A is not correct.
The density of the air determined how many atoms of air can occur in a particular volume, In other words, it determines how tightly or loosely atoms of air are packed in a particular volume.
Hence, when the air density will increase, the molecules will be more tightly packed and the pressure will be more.

Answer:
1. Salts. 2. Oil reserves. 3. Gold deposits. 4. Minerals

- Also, they consist of high-value items like gold, silver deposits as these have been constantly been drilled for such precious metals. Similarly, various minerals and salt content ate known to have been found in these deposits.
- The presence of active deposits is found near the continental plate boundary. Certain SEZ special economic zones have neb thus made to help preserve the mineral and oil wealth of nations.
