Answer:
B. local water contamination
D. destruction of ecosystems
Explanation:
The mining, be it a surface one or underground one, has several negative impacts on the surrounding area. Two common negative impacts of both types of mining are contamination of the local waters, as well as the destruction of ecosystems.
The waters get heavily polluted with toxic chemicals pretty much always ad everywhere where there is mining. The main reason for this is that the nus-products from the mining are released into the waters. This causes high level pollution of the waters, thus making it not good for anything, and the aquatic life in the waters dies out rapidly.
The fact that the waters are heavily polluted means that everything that comes in touch with them becomes heavily polluted as well. Also, apart from releasing chemicals in the waters, the mining requires space, so the area is cleared out, and after that lot of toxic material is disposed on it. The majority of the plants can sustain that, so they die out, and since they are the basis of the ecosystems, the animals die out as well.
Are you sure you wrote it right? :-(
The function f(x)=2x-5 is a linear function.
Unless otherwise stated (and that does not seem to be the case) in the real numbers domain, x may assume any value.
The same can be said to y.
So, the lowest output value approached by this function is -∞
(minus infinity).

Answer:
Explanation:Destruction of natural vegetation is primarily caused by deforestation. Other major causes are wildfire and over-exploitation. Deforestation not only occurs as a result of firewood extraction by the local population but also as a result of the creation of arable as well as pastoral land.
The correct answer is - biomass from the decomposing grasses.
The Midwest is a region known for its highly fertile soil. The reason for this is that the weathered bedrock combines with huge amounts of biomass. The biomass is almost entirely form the grasses. The grasses grow naturally in this region and they dominate the landscape. They grow and die out relatively quickly, as most of those grasses are one season grasses. They manage to create very large amounts of biomass every year, and also they decompose very quickly. The grasses also are high in nutrients, so once decomposed, they give the soil a lot of nutrients as well, which makes it very fertile and suitable for agriculture.
