Personally I would say it's A (apart from the installation costs which may make it a little expensive) but it does involve certain aspects of D also as wind energy doesn't cause pollution. So either A or D!
Hope I was of help! :)
Which of these natural processes can we actually see taking place?
- None of the above
Radius of earth as given in question = 6400 km
Height of the air balloon = 200 m
= 0.20 km
Now
Let us assume the distance up to which one can see from the balloon = d
Then
d=sqrt [<span><span><span>(R+h<span>)2</span>−<span>R2]
</span></span></span> = sqrt [</span><span><span>2Rh+<span>h^2]
= sqrt [2 (6400 * 0.20) + (0.20)^2]
= sqrt [(2 * 1280) + 0.04]
= sqrt [ 2560 + 0.04]
= sqrt [2560.04]
= 50.6 km
A person in the balloon can see up to a distance of 50.6 km. I hope the answer has helped you.</span></span></span>
The correct answer is - rain forest protection.
One of the biggest environmental concerns in the Central American region is the protection of the tropical rain forests. Even though Central America is a relatively small region, it has an abundance of rain forests, but as the years pass by, there's major environmental concerns about their well being, and even about their existence.
Central America is in general a poor region with lot of problems, and unfortunately, when the people don't have it easy, they don't seem to care about the environment, especially if they see it as a source of income. The concerns are becoming bigger and bigger about the rain forests because more and more area is cleared out so that the land can be used for agriculture. Also the poaching of exotic animals, as well as the selling of high quality timber on the black market, are making a huge problem in the protection of the rain forests.
