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.
Rural- relating to, or characteristic of the country side rather than the town. For a more simple definition it's basically people who live out in the country side. Example- She lives in a rural area.
Answer:
V ≈ 4577.204 cm^3
Explanation:
Use the volume formula V=4/3πr^3 to find the volume. Since you need the radius but are given the diameter, divide it by 2 to get half.
21.4/2 = 10.7
Now plug that into the formula and solve:
V=4/3πr^3
V=4/3π(10.7)^3
V= 4/3π(1,092.7272)
V= 4/3 * 3432.903
V= 4 * 3432.903/3
V = 13731.614/ 3
V ≈ 4577.204 cm^3 or whatever unit is stated.
1. Pack a first aid kit, Water, and snacks
2. Try looking at the map, read the riddle, and think about the placethat they are talking about!
3. I say don't worry about "WHERE?" the adventure it's self is the mystery.
4. HAVE FUN!
Mostly its the tectonic plates that shift under us that causes earthquakes, how they shift changes the damage the earthquake can cause so tectonic plates unless u want the mythological one which is some earth god scratching his back
