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:
B. Heat absorption increases as the albedo decreases
Explanation:
The ice has very high albedo. The reason for this is that it has white coloration, and the light coloration are highly reflective of the sunlight. As the ice melts though, the water surface increases, and the water, unlike the ice, has the capability of absorbing much more heat. With much more water, there will be much more absorption of heat, and since the water has low albedo on only 10, the albedo will decrease on a global level.
