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.

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.
An example of an igneous rock low in silica is granite?
Granite is actually high in silica, which is why it is considered a felsic igneous rock. An example of an igneous rock low in silica is basalt, which is mafic in composition and contains less silica than granite.
Does rhyolite have a more mafic composition than basalt?
No, rhyolite has a more felsic composition than basalt. Rhyolite is rich in silica, which makes it a felsic rock, while basalt is more mafic due to its lower silica content.
Which is more dense basalt or granite?
Granite.
What is a dark colored low silica rock?
Basalt is a dark-colored, low-silica igneous rock commonly found as a result of volcanic activity. Its composition typically contains around 50% silica, making it relatively low in silica compared to other igneous rocks like granite.
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.

No, rhyolite has a more felsic composition than basalt. Rhyolite is rich in silica, which makes it a felsic rock, while basalt is more mafic due to its lower silica content.
Is igneous rock granite or basalt?
Both granite ans basalt are types of igneous rock.
Which is more dense basalt or granite?
Granite.
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 is a dark colored low silica rock?
Basalt is a dark-colored, low-silica igneous rock commonly found as a result of volcanic activity. Its composition typically contains around 50% silica, making it relatively low in silica compared to other igneous rocks like granite.
Is basalt high or low?
Basalt is a type of rock that is considered to have intermediate silica content compared to other types of rocks. It is not high in silica like granite, but not low like ultramafic rocks. It is commonly found in volcanic environments and has a fine-grained texture.
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.
The material on the surface of the moon is similar to 'basalt' or 'granite'?
The material on the surface of the moon is more similar to basalt rather than granite. Basalt is a common volcanic rock that makes up the dark plains, or maria, on the moon, while granite is found more commonly on Earth's continental crust.
Which has a greater percentage of biotite in it rhyolite or basalt?
Rhyolite typically has a greater percentage of biotite compared to basalt. This is because rhyolite is a silica-rich volcanic rock that contains more biotite, a mica mineral, which forms in silica-rich environments. Basalt, on the other hand, is a silica-poor volcanic rock that generally contains lower amounts of biotite.
The rock that underlies the oceans is granite?
The rock that underlies the oceans is primarily basalt, not granite. Basalt is a volcanic rock that forms from solidified lava, and it makes up most of the oceanic crust. Granite, on the other hand, is a different type of rock that is more commonly found in continental crust.
