Answer:1. Yes, there are magma of different composition in existence. silicate mineral become molten at the same temperature of 1200 degree centigrade in igneous rock formation and this does not stop the composition of magma which are of three types basalic, andesitic and rhyolitic each of them have different composition ranging between iron, magnesium and calcium.
2. Partial melting is the reason why we have different forms of rock, this is because the mantle is composed of different minerals, these minerals doesn't melt uniformly, a mineral with low melting point will turn to liquid while the one with high melting point will turn to solid crystals. As the magma melts and flow slowly before it cools into solid rock it undergoes some physical and chemical changes which causes differences in the rock formed.
3. The last question depends on ever individual's location, where i am i can easily go and see granite at a mining site that deals with construction rocks which is an example of igneous rock.

The correct answer is - True.
Even though, we are practically speaking about the same people, with same origin, and same language, there has been rivalries and hatred between them for centuries. In general, the biggest problem between them was created by the religion. The Croats are Catholic, the Serbs are Orthodox, and on top of it we have the population in Bosnia that was Christian, but converted to Islam under the pressure of the Ottomans. Big rivalries came out from this, and unfortunately, the conflicts between them ended up with genocides, the Croats killed Serbs in the World War II, than the Serbs in the early 90's took revenge and were killing Croats, and in the middle of it were the Muslims which also suffered genocide over them.
