A. This is because these formations occur on the surface and can range from mountains to forests.
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: C. Ionic
Explanation: The transfer of one or more electrons from one atom to another means that certain atoms are "amplified" by negative charge, since the electrons are negative, while the other atoms from which the electrons leave become positive. This means that such atoms become negative and positive ions, causing each other to attract opposite charged ions, creating an ionic bond.
