Well I’m no meteorologist, but it seems to me the closer you get to the equator the denser the air mass becomes. The farther away it gets from the equator, it obviously gets less dense. I do notice though that the purple are is Greenland, northern Russia and Northern America. Which leads me to believe that it’s more mountain land and it’s density is compared to that of cooler air.
Answer:
D. Pollution
Explanation:
The pollution is a consequence of the growing economy in advancing nations. The economy is growing, and transforming rapidly in the last two decades. Some characteristics of this change are: technological innovations and modernization, competition in the global market, etc. However, the pollution still a severe problem in developing countries. This is because, these countries doesn´t have a substantial economic growth, therefore cannot afford to focus on environmental problems.
Developing countries need to decide between keeping competitive prices to obtain and sustain economic growth while the poverty decrease. This decisions usually lead to environmental pollution. For example In sub-Saharan Africa, depends mainly on natural resources. They over exploits of natural resources such as coal, oil and gas, gold, copper. This cause pollution in air, water and land, and it can impact the climate change.
They should care more about pollution, because it also affects the health, sometimes leads to death of the population. Is important to mention that per year millions of people can be affected.
Answer:
The representative fraction of photo will be 1:3600
Explanation:
Orthophoto is constructed geometrically where there is no distortion unlike maps.
The width of a five lane freeway is 0.2 inches.
Assuming the width of each lane to be 12 feet, then the total width of all the five lanes is 12×5=60 feet
We know that 1 feet = 12 inches
So, 60 feet = 60×12= 720 inches
So , we get that 0.2 inches on the orthophoto is 720 inches on the ground.
So, 1 inch on the orthophoto = 
inches on the ground = 3600 inches.
Thus the scale is 1:3600
