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.

Extreme heat events are becoming more common as a result of climate change. Extreme heat will certainly affect more locations, more frequently, more intensely, and for longer periods of time. With more hot summer nights, there is less “cooling off” at night.
<h3>What is global warming?</h3>
Long-term changes in temperature and atmospheric trends are referred to as climate change.
While these changes are natural, human operations have been the primary driver of global change throughout the 1800s, owing to the exploitation of fossil fuels (such as coal, oil, and gas), which generates heat-trapping gases.
Extreme weather is directly killing animals, destroying their habitats, and causing havoc on people's livelihoods and communities as a result of global warming.
Therefore, as climate change develops, dangerous weather events are becoming more common and severe.

Answer:They are both necessary for organisms to survive
Explanation:
Well, first we have 4 quarters, or $1. Then, since 2 nickels= 1 dime, we also have 6 dimes and 1 nickel. Simplified, he now have $1.65.
