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.
Answer:
Weathering, mass wasting, erosion, and deposition--Endogenic process
Volcanic, tectonic, and isostatic processes---Endogenic process
Explanation:
Weathering, mass wasting, erosion, and deposition are the main exogenic processes that occurs outside the earth surface where as Endogenic process consist of volcanic, tectonic, and isostatic processes that occurs inside the earth. exogenic processes are responsible for the formation of different types of landscape while endogenic processes are responsible for the formation of most important mineral resources.
Though the region doesn't receive much water during the rainy season, the Gobi receives more moisture during the winter. The Siberian Steppes, north of the Gobi, are responsible for much of the snow that appears on the desert. High winds sweep the snow from the Steppes, distributing it over the dunes of the Gobi during the winter months. Because most of the desert is actually rock rather than sand, however, even this extra moisture has little effect on the region's ecosystem.
<span>These high winds are also the major cause of the temperature extremes common to the Gobi. Both cold and hot air are swept across the desert unhindered. The environment of the Gobi can be harsh and unforgiving, but the area remains an important piece of history and culture to the world.</span>Most deserts suffer from rapid changes in temperature throughout the year, but the Gobi has a climate of extremes. The temperature has been known to shift 60 degrees Fahrenheit in as little as 24 hours. It can get down to minus-40 degrees in the winter, and as hot as 122 degrees in the summer. Though the desert only receives an average of 7.6 inches of rainfall per year (compare that to the Amazon Rainforest which recieves 9 feet), but that's not the only precipitation. Thanks to region's height above sea level (up to 5,000 feet in some areas) and northerly position on the globe, it's not unheard-of to see frost or even snow atop the dunes occasionally.
