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.
Lunar eclipses occur when the earth comes between the Sun and the Moon. This positioning quickly changes due to both the Earth and the Moon orbiting around the sun and each other.
Answer: 5am on Sunday, May 3rd.
Explanation:
Plane left at 12pm and takes 17 hours.
Add 12 and 17:
= 12 + 17
= 29
There are 24 hours in a day. The number of hours into the next day is therefore:
= 29 - 24
= 5 hours
If the plan arrives 5 hours into the next day, that would mean that it arrived at 5am. Date of the next day is May 3rd, a Sunday.
