coal, copper, lead, iron, natural gas, timber, bauxite, and uranium.
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.
Answer:
Explanation:
“Southwest Asia: Pakistan, Afghanistan, Iran, Iraq, and the oil-bearing states bordering what now must tactfully be termed simply 'the Gulf,' all constituting a politically seismic zone of incalculable explosive potential.” Campbell later gave a similar definition: “'Southwest Asia' includes everything from the eastern

The correct answer is - Focus.
Focus of the earthquake, also referred to as hypocenter, is the location/point where the earthquake starts. It is usually few kilometres below the surface. At this spot the ground raptures after which seismic waves start radiating outward in all directions. The focus is located below the epicenter, or rather the epicenter is above it because the location of the epicenter is determined by the location of the focus, so the epicenter represents the closest point on the surface of the Earth from where the focus is.
