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.

international borders
Explanation:
The political maps are type of specialized maps that are showing the reader of the map the countries, be it in the whole world, in a region, or in a smaller area.
These maps are always showing the international borders between the countries, which is actually its main purpose, differentiation of the countries and representation of their borders.
Very often, the major cities tend to be represented as well, and it can only be the capital cities, or cities that are very large and important.
The major bodies of water too tend to be represented, as the borders between the countries often go through a water body, or the water bodies are surrounding a country.
Every country is usually depicted with different color, so that the reader of the map is able to differentiate the countries much more easily.
The answer is B I think...
<span>The outer edge of a meander, where material is being eroded, is called a cut bank.
A cut bank is found on the outside bank of a water channel and it continuously erodes. You can find a lot of them in more mature or meandering streams. </span>
