What are two examples of felsic rock?
Granite and rhyolite are examples of felsic rocks. These rocks are generally light in color and rich in minerals like quartz, feldspar, and mica. They are formed from the crystallization of magma with high silica content.
What 2 rocks are high in silica?
Two rocks that are high in silica are granite and rhyolite. Granite, an intrusive igneous rock, typically contains around 70-75% silica, while rhyolite, an extrusive igneous rock, can have silica content ranging from 68-78%. Both rocks are associated with volcanic activity and are commonly found in continental crust. Their high silica content contributes to their lighter color and lower density compared to rocks with lower silica levels.
What two rocks type are niether felsic nor mafic?
The two rock types that are neither felsic nor mafic are ultramafic and intermediate. Ultramafic rocks contain very low silica content and are primarily composed of olivine and pyroxene, while intermediate rocks have a silica content between that of felsic and mafic rocks, typically consisting of a mix of plagioclase feldspar and amphibole. Examples of ultramafic rocks include peridotite, and examples of intermediate rocks include andesite.
What are some examples of felsic and mafic rocks?
Granite and grandiorite are two felsic rocks but I'm seeing that some people cosider granite mafic.
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 are two examples of fine-grained igneous rock?
Two examples of fine-grained igneous rocks are basalt and rhyolite. Basalt is a dark-colored rock with a composition rich in iron and magnesium, while rhyolite is light-colored and has a high silica content. Both rocks form from the cooling and solidification of molten magma.

What are two examples of sedimentary rocks?
Limestone or Sandstone are two examples of sedimentary rocks. Two examples of sedimentary rocks are slate (fine silt) and chalk (shell remains of sea creatures).
What are two examples of fined grained igneous rocks?
Basalt and rhyolite are examples of fine-grained igneous rocks.
What are two examples of fine-grained igneous rocks?
Basalt and rhyolite are examples of fine-grained igneous rocks.
What does magma with high silica content form?
When it cools and crystallizes into rock, the rock will be described as felsic igneous rock. Examples of felsic igneous rocks are granite, rhyolite, and pumice.
Name two rocks from the intermediate family?
Diorite and andesite are two rocks from the intermediate family. These rocks are formed through the cooling and solidification of magma with intermediate silica content, between that of felsic (granitic) and mafic (basaltic) rocks.
What are examples of two intrusive rocks?
Basalt and sandstone.
