What else can I help you with?
Can igneous rocks be found on Mars If so what can you conclude about Mars' history?
yes of coarse!
Explain how the silica content of molten materials affects the color of igneous rocks?
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.
How does silica from molten material affect the color of igneous rock?

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.
Why are granitic igneous rocks light in color?
granitic igneous rocks are light colored because of a lower density than basaltic rocks
What clues provide how igneous rocks where formed?
Its color
What color will igneous rocks be if they are low in silica?
brown
How does chemical composition effect igneous rocks?
It affects the color.
How do you classify igneous rocks?
Look at them. There shape, size, color and feel! Dont worry you will figure it out....
When molten rocks cools what rocks form?
igneous rocks
Why are granitic igneous rocks lighter in color than basaltic rocks?
Granitic igneous rocks are lighter in color than basaltic rocks because they contain more quartz and feldspar minerals, which are typically light in color. Basaltic rocks, on the other hand, contain more dark-colored minerals like pyroxene and olivine, giving them a darker color.
What does the word felsic?
The word felsic is used to describe igneous rocks that are rich in silica and alkali feldspar. Such rocks tend to be light in color and have a lower density than other igneous rocks.
Is igneous rock red?
Not necessarily. Igneous rocks come in a variety of colors depending on their mineral composition. While some igneous rocks may be red due to the presence of minerals like iron oxide, many others can be black, white, green, or even multicolored.
