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.
Water is the source of life. It is one of the only ways to survive so without water, there is no life.
Answer and Explanation:
It is true fact that organic matter in soil diminishes with time yet it is unseemly to utilize this information for lab manual since we make heaps of changes to recoup natural issue in the dirt before going for another period of editing. Notwithstanding when the yield is reaped, the buildup of the previous harvest goes about as a natural fuel for the following yield. Here and there when we develop vegetable harvest, it rather adds minerals to the soil.
But if there is comparison between earlier soil and current soil, I figure it would be nearly increasingly precise for the as of late cleared soil since here, we can quantify the exhaustion of natural issue plainly. while the soil which had been cultivated and prepared for horticulture before, there probably come different changes because of enormous number of factors.l
The ocean floor or seabed can be divided into three major regions: the continental margins, abyssal plains, and mid-ocean ridges.
