Does dark colored rock with low silica content describe granite?

Granite is a silicate because it contains 70-77% silica (SiO2).
Granite is a rock, and silica is mineral containing the chemical elements silicon (Si) and oxygen (O). Si and O chemically combine to form SiO2.
Rocks are made up of minerals, which are made up of chemical elements.
Because silicon and oxygen are the two most common chemical elements in the Earth's crust, silicate rocks are very common.

What generally describes granite?
as dark colored rock with low silica content
A light colored igneous rock with silica content and explosive eruptions?
Andesite
Which igneous rock out of granite basalt andesite and peridotite has the lowest silica SiO2 content?
Peridotite, a type of ultramafic rock composed largely of the mineral olivine, has the least silica.
What is composition of acidic igneous rocks?
Acidic igneous rocks, also known as felsic rocks, are composed primarily of light-colored minerals such as quartz, feldspar, and mica. These rocks have a high silica content and typically have a lower iron and magnesium content compared to mafic rocks. Examples of acidic igneous rocks include granite and rhyolite.
What does silica content?
Any metrial or thing which containts silica in it is call silica content..
What is a light colored rock with a high silica content?
granite
What generally describes granite?
as dark colored rock with low silica content
What is a light colored rock that has high silica?
Felsic igneous rocks with alkali feldspars, quartz, and mica. Examples would include rhyolite, pumice, granite, and obsidian.
Granite jigneous rocks are light-colored lower in density thank basltic rock and high in silica content?
Yes
Does gabbro have a higher silica content than granite?
Gabbro has less silica than granite.
What is the average silica content for granite?
72%.
How does granite differ from gabbro in coloring and silica content?
Granite is lighter in color and higher in silicate mineral content.
What is the rock that has high silica and light colored other than granite?
quartzite
IS granite low in silica and dark colored?
Granite can exist in several colors. The colors are based on the ratio of feldspar, quartz, and mica.
An example of an igneous rock low in silica is granite?
False. Basalt would be an example of an igneous rock with a low silica content.
Describe the different minerals that determine the color of granite?
Magma that is high in silica usually forms light-colored rock, such as granite. Grantis, however, comes in many shades and colors, from nearly black to light gray, red, and pink. The mineral composition of granite determines its color. ^______^
A light colored igneous rock with silica content and explosive eruptions?
Andesite
