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:
Los mares cerrados, como el Mar Mediterráneo, presentan mayores niveles de contaminación porque son entera o mayoritariamente formados por cuencas endorreicas, las cuales no tienen salida directa hacia el océano. De esta manera, las corrientes marítimas no desagotan sus residuos en el océano, sino que continúan retroalimentándose de manera cícilica, con lo que el conjunto de desechos que viaja en dichas corrientes se queda constantemente dentro de la misma cuenca.
Answer:
La opción incorrecta es D. Si bien es cierto que África presenta diversos problemas socioeconómicos, no es cierto que se trata del único continente con bajo nivel de vida.
Así, si bien la mayoría de los países africanos están sumidos en la pobreza, esta condición se encuentra en todos los continentes, con ejemplos como Ucrania o Moldavia en Europa, Haití o El Salvador en América, Afganistán o Birmania en Asia, o las Islas Salomón en Oceanía.
