If all silicate mineras melted at exactly the same temperature, would magmas of different compositions even exist? How is partia
l melting so important for generating the diffrent kinds of rocks on Earth? Last queston. If you wanted to go see an igneous rock outcrop where is the closest location located, and what igneous rock would you see.
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.
Hernando de Soto was a Spanish explorer who was looking for gold in a journey across Georgia because they want to explore the gold for the Spanish empire in order to boost the economy and influence of the empire and make it stronger financially against enemies. He also bring war to Georgia when he and army had encounter with the native peoples and killed thousands of them.
<span>Base from the graph the number
of degrees of longitude that separate new York and reno Nevada is 120 – 75 = 45
degrees of longitude. The time difference can be calculated by dividing it by
15 degree because for every 15 degrees there is 1 hr difference. 45 / 15 = 3 hr
difference</span>
