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 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.
Light colored igneous rocks are part of what family?
Light colored igneous rocks are part of the felsic family. These rocks are rich in silica and aluminum minerals, giving them their light color. Examples include granite and rhyolite.
What are light colored often intrusive igneous rocks containing a high percentage of silica called?
Light colored often intrusive igneous rocks containing a high percentage of silica are typically called granitic rocks. They are commonly found in continental crust and have a composition similar to granite, containing minerals like quartz, feldspar, and mica.
What is the difference between acidic and basic igneous rock?
Acidic igneous rocks have a higher silica content and are more viscous, leading to explosive eruptions. Basic igneous rocks have a lower silica content and are less viscous, resulting in more fluid lava flows. Additionally, acidic rocks tend to contain more quartz and feldspar minerals, while basic rocks are enriched in minerals like olivine and pyroxene.
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.
What is A light colored igneous rock with high silica context explosive eruptions?

A light colored igneous rock with silica content and explosive eruptions?
The rock is likely rhyolite, which is a light-colored igneous rock with high silica content. Rhyolitic magma is viscous and tends to trap gas, leading to explosive eruptions with ash and pyroclastic flows. The high silica content of rhyolite contributes to its light color and explosive nature.
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 light colored ofrten intrusive igneous rock containing a high percentage of silica are called?
felsic
When silica is in a rock does it make it lighter or darker?
Generally, igneous rocks with more silica are lighter in color.
In general how does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Light-coloured igneous rocks, such as granite, have a higher silica content and lower iron and magnesium than darker ones, such as basalt. Since iron and magnesium are very dense minerals, this makes darker igneous rocks more dense than lighter ones.
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.

Light colored often intrusive igneous rocks containing a high percentage of silica are typically called granitic rocks. They are commonly found in continental crust and have a composition similar to granite, containing minerals like quartz, feldspar, and mica.
Relationship between silica content and overall color of igneous rock?
The higher the silica content in an igneous rock, the lighter the overall color. This is because silica-rich rocks tend to be lighter in color due to the presence of minerals like quartz, which is typically white or light-colored. On the other hand, rocks with lower silica content tend to be darker as they contain minerals like mafic minerals (such as olivine and pyroxene) which are dark in color.
