Felsic igneous rocks with alkali feldspars, quartz, and mica. Examples would include rhyolite, pumice, granite, and obsidian.

What is a light colored rock with a high silica content?
granite
What is a dark colored low silica rock?
Mafic igneous rocks, like basalt, are dark colored and low in silica.
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. ^______^
The light colored rock that makes up most of the continental crust is what?
Granite is the light-colored rock that makes up most of Earth's continental crust.
Would you expect a light gray igneous rock to be rich or poor in silica?
rich
What is a light colored rock with a high silica content?
granite
What is the rock that has high silica and light colored other than granite?
quartzite
What is A light colored igneous rock with high silica context explosive eruptions?
majority
What is light colored ofrten intrusive igneous rock containing a high percentage of silica are called?
felsic
Granite jigneous rocks are light-colored lower in density thank basltic rock and high in silica content?
Yes
What color will igneous rock with high levels of silica be?
An igneous rock with a high level of silica will have a light color.
A light colored igneous rock with silica content and explosive eruptions?
Andesite
Is and igneous rock low in silica dark colored or light colored?
Generally, igneous rocks that are low in silica are dark relative to those that are high in silica. This tendency is largely the result of rocks low in silica having increased iron. Iron minerals tend to adsorb significant amounts of the visible spectrum and hence appear dark. I want to emphasize that this is a general tendency and there are exeptions -- obsidian which is very high in silica is typically a dark to black rock and a special igneous rock call carbonatite is very light in color but has little silica.
What is a dark colored low silica rock?
Mafic igneous rocks, like basalt, are dark colored and low in silica.
What is a dark-colored low silica rock?
Mafic igneous rocks, like basalt, are dark colored and low in silica.
What is the explanation for the difference between texture and composition?
Texture is the physical description of the rock. I always think of this as the property you can figure out with your eyes closed (how does the rock "feel"?). Texture types included coarse-grained, fine-grained, glassy, etc. Composition is the chemical description of the rock, what minerals it is made of. For igneous rocks the terms used are felsic (high in silica, usually light colored) to mafic (low in silica, high in iron and magnesium, usually dark colored).
What rock in the igneous family are medium colored and have no silica?
Igneous rocks that are medium colored and have no silica are called mafic rocks. They are mainly composed of magnesium and iron.
