The correct answer is D. Water diversion and pumping has allowed humans to grow crops in areas where natural supplies have been limited. A major challenge that exists in these regions due to over irrigation has been soil erosion.
Explanation:
Soil erosion is a phenomenon of displacement of materials on the surface of the outermost layer of the earth's crust. It is one of the forms of regression and degradation of the soil. Protection against this erosion is an issue for the preservation of the agronomic quality of agricultural soils, the quality of surface water and the security of dwellings and infrastructure (covering of roads, appearance of muddy flows, clogging or filling of networks rainwater collection).
The answer is Greenland, there was a story were lot's of people lived on Iceland but Iceland was all green, this person found Greenland but it was covered in ice, he called it Greenland to make people come there.
Base on the scenario been described in the question, the correct is 2.9 mb, subtracted from
The substraction is because the base station is below or under the sea level and the atmospheric pressure decreases or reduces with the height. I hope this explanation is helpful
