9. When you think of a lobster, you might think of a bright red creature. Most lobsters are a brown to olive-green color in the wild, with only a reddish tinge. Lobsters have a carotenoid pigment called astaxanthin in their shell, which provides a red coloring.
Is granite homogeneous or heterogeneous substance? Granite is a heterogeneous substance. This is due to the fact that it does not appear to be consistently made of one material.
Granite is an igneous rock composed of mostly two minerals: quartz and feldspar. It is an intrusive rock, meaning that it crystallized from magma that cooled far below the earth's surface.Its name is derived from the Latin word 'granum', which means 'grain', a reference to the easily-seen minerals in the rock.ranite contains mostly quartz and orthoclase feldspar; other minerals make up less than half of the rock. The magma that crystallizes into granite likely forms in the upper mantle or lower lithosphere, where other rocks partially melt. Granite is used in buildings and some granite is mined for rare elements.
