Answer:
<em>Different rocks have high, medium, and low melting points.</em>
Explanation:
There is a considerable range of melting temperatures for different compositions of magma. All the silicates are molten at about 1200°C (when a part of rock) and all are solid when cooled to about 600°C. Often the silicates are grouped as high, medium and low-melting point solids.
answer is: O
o goes from 0 to -2, so it is the element that is reduced
