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.
An ecosystem has abiotic(no living things like water and wind) and also biotic(living things) while a community is biotic things
This shows a cinder cone volcano. It forms when cinders erupt again and again, piling up around the vent to form a steep, cone-shaped hill.
Answer: The answer is cup 1
Explanation: This is because ocean water has more density due to the amount of salinity it contains.
Water is the source of life. It is one of the only ways to survive so without water, there is no life.
