Answer:
The correct answer is - natural selection.
Explanation:
Natural selection is a process of adapting according to the environmental change in order to survive and reproduce and increase their number. It is represented by Darwin for the first time. Natural selection leads to evolution.
In this case, White moths adapt according to the environment by increasing the population of black moths in order to blend with the surrounding and as the result, black moths are more likely to produce and survive and passed this trait to the next generation.
Weight of air
Depending on elevation, the air pressure
varies. This is because of the weight of the air that is exerting pressure on
earth. At higher elevation, there is less layer of air that is exerting pressure
so the atmospheric pressure is also less. At lower altitudes or at sea level,
more layer of air is exerting pressure so the atmospheric pressure is also
more. The sun’s energy has nothing to do with air pressure. The energy that the
Earth gets from the sun is more or less constant. The same with density of
nitrogen, and the earth’s magnetic field, they have nothing to do with air
pressure.
