Answer:
B. intrusion of magma into fractions
Explanation:
A pluton is a type of rock that is formed when magma cools and solidifies underground, they are an intrusive igneous rock (forced into other layers of rock), usually in cracks. The three main types of pluton are bysmalith (cylindrical), lopolith (mushroom-shaped), and laccolith (blister-shaped).
Because magma is under high pressure and takes a long time to cool, it allows time for the formation of large crystals. Therefore, plutonic rocks have coarse-grained crystals that come in many different colors and sizes. A good example is granite.
<em>Considering this information we can conclude that pluton is not manmade rock, they come in different sizes (not only large) so the correct answer is B. intrusion of magma into fractions. </em>
I hope you find this information useful and interesting! Good luck!

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.
