Explain how the silica content of molten material affects the color of igneous rocks?
Silica in molten material tends to crystallise as quartz, which is white or mostly pale in colour. So felsic rocks (from silica-rich magma) tend to be pale, while mafic rocks (from silica-poor magma) tend to be dark in colour.
What is an igneous rocks color determined by?
An igneous rock's color is mainly determined by its silica content.
Why are granitic igneous rocks light in color?
granitic igneous rocks are light colored because of a lower density than basaltic rocks

How the silica content of molten affects the color of igneous rocks?
The more silica contained in a rock, the lighter in color it will be.
How silica content of molten material affects the color of igneous rocks?
The more silica contained in a rock, the lighter in color it will be.
How the silica content of Molten material affects the color of igneous rock's?
The more silica contained in a rock, the lighter in color it will be.
How does silica from molten material affect the color of igneous rock?
The majority of minerals associated with igneous rocks are silicates. It is the proportion of certain silicate minerals that affects the color of igneous rocks. Igneous rocks that are high in orthoclase feldspar, quartz, and muscovite mica will be lighter in color than igneous rocks that are higher in olivine, pyroxene, amphibole, and biotite mica.
