How does granite differ from gabbro in coloring and silica content?
Granite is typically light in color with a higher silica content, while gabbro is dark in color with a lower silica content. This difference in silica content results in contrasting mineral compositions and textures between the two rocks.
Which rock has more silica granite or basalt?
Granite has more silica content than basalt. Granite is a felsic rock with higher silica content, while basalt is a mafic rock with lower silica content.
Is gabbro a felsic rock?
No, gabbro is not a felsic rock. Gabbro is classified as a mafic rock due to its dark color and high content of iron and magnesium minerals, while felsic rocks are light-colored and have a higher silica content.
What rock has more silica granite or basalt?
Granite has more silica than basalt. Granite is a light-colored, coarse-grained igneous rock made up of quartz, feldspar, and mica, which are minerals rich in silica. Basalt, on the other hand, is a dark-colored, fine-grained igneous rock with lower silica content compared to granite.
What is the average silica content for granite?
72%.

What is a light colored rock with a high silica content?
granite
Can gabbro contain the moneral quartz?
No, gabbro typically does not contain quartz. Gabbro is a coarse-grained, dark-colored intrusive igneous rock composed mainly of calcium-rich plagioclase feldspar and pyroxene minerals. Quartz is not a common mineral in gabbro due to its typically silica-poor composition.
What generally describes granite?
as dark colored rock with low silica content
What is a magmas viscosity related to?
The silica content. A higher silica content results in a more viscous magma.
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.
What is a magma's viscosity directly related to?
The silica content. A higher silica content results in a more viscous magma.
What is a light colored rock that has high silica?
A light-colored rock that has high silica content is likely to be granite. Granite is a common igneous rock composed mainly of quartz, feldspar, and mica, and is known for its high silica content and light color.
What is the behavior of lava with silica content being high and low?
Lava with high silica content tends to be more viscous and flow more slowly, leading to explosive eruptions. In contrast, lava with low silica content is less viscous and flows more easily, resulting in gentler, effusive eruptions.
Does AA lava have a lot of silica?
No, AA lava has low silica content as it is formed from basaltic magma which is low in silica. This type of lava is less viscous and flows more easily compared to lava with higher silica content.
