What is a sialic rock?
There is no such thing as a "sialic rock." However, "sial" refers to the upper layer of Earth's crust, which is rich in silicon and aluminum. It is commonly found in continental crusts and is also known as "granitic" or "felsic" rock.
What is an unidentified light colored igneous rock that is made up of potassium feldspar and quartz what family of igneous rocks does the rock belong?
Granite is an igneous intrusive rock (crystallized at depth), with felsic composition (rich in silica and predominately quartz plus potassium-rich feldspar plus sodium-rich plagioclase) and phaneritic, subeuhedral texture.
Is an igneous rock a element?
No Igneous rock is consistently a compound - a mixture of elements. Although there are variations in composition, igneous rock is usually made up of roughly half oxygen, roughly one quarter silicon, and lesser, but significant, quantities of aluminum, calcium, sodium, potassium, and magnesium., with a sprinkling of other elements.
What life is in rock pools?
Rocks contain silicon dioxide and are a compound Above is true. But if the type of rock is igneous, sedimentary, or metamorphic then it can contain minerals, other rock fragments, and magma.
What type of rock forms when molten rock cools?
Rock that forms from molten rock that cools and solidifies is called igneous rock.
What is the dark colored igneous rock with rich in iron and magnesium?
These rocks are called mafic igneous rocks, such as basalt. == ==
What is acidic rock?
In geology, the term acid rock refers to an igneous rock which is relatively high in silica.
Melted rock that flows to the surface cools quickly forms?
Igneous rocks are formed when molten hot rock flows to the surface of the Earth and rapidly cools down. The crystals that form are rich in silicon and oxygen.
What is a sialic rock?
There is no such thing as a "sialic rock." However, "sial" refers to the upper layer of Earth's crust, which is rich in silicon and aluminum. It is commonly found in continental crusts and is also known as "granitic" or "felsic" rock.
Light colored igneous rocks that are rich in aluminum potassium silicon and sodium are called what kind of rocks?
They're described as felsic igneous rocks.
Would you expect a light gray igneous rock to be rich or poor in silica?
rich
Is rhyolite an polymerization sedimentary rock?
No, rhyolite is a silica-rich volcanic or igneous rock.
Dark colored igneous rock rich in iron and magnesium?
Dark, mafic rock is relatively rich in iron and magnesium.
What are 2 classifications of igneous rock?
Felsic and Mafic are two very broad classifications for igneous rocks. This is based on their composition. Felsic rocks are rich in silicon and aluminum (e.g. granite) while Mafic rocks have higher concentrations of magnesium and iron (e.g. basalt).
What is an unidentified light colored igneous rock that is made up of potassium feldspar and quartz what family of igneous rocks does the rock belong?
Granite is an igneous intrusive rock (crystallized at depth), with felsic composition (rich in silica and predominately quartz plus potassium-rich feldspar plus sodium-rich plagioclase) and phaneritic, subeuhedral texture.
What is the chemical composition of the Earth's crust?
The Earth's crust is formed mainly from the elements aluminum, silicon and oxygen in the form of silicates & aluminum oxides and occurring as silicate rocks.Silicate minerals are abundant in all three rock types (igneous, metamorphic, and sedimentary) comprising the crust, but the crust is composed mainly of silicate rich igneous rock. The continental crust is composed of the lighter 'felsic' igneous rock (granitic in nature), higher in aluminum, sodium, and potassium; the oceanic crust is composed of the heavier, darker, 'mafic' igneous rock (largely basalt) which is higher in iron and magnesium than the continental crust.Crust composition: Oxygen, Silicon, Aluminum, Iron, in that order.Overall composition of the entire Earth: Iron, Oxygen, Silicon, Aluminum, in that order.Magnesium and Iron
What kind of rock is a quartz?
Quartz is a mineral composed of silicon and oxygen, SiO2.
