What else can I help you with?
Does rhyolite or basalt have more silica in it?
rhyolite
What igneous rocks cool above ground?
Igneous rocks that cool above ground are called extrusive or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks form when magma erupts onto the Earth's surface and cools rapidly.
What are rocks that form as a resutlt of cooling magma?
Rocks that form as a result of cooling magma are igneous rocks. They can be classified as intrusive rocks (cooled slowly beneath the Earth's surface) or extrusive rocks (cooled quickly at the Earth's surface). Examples include basalt, granite, and rhyolite.
What rock is formed when magama cools at the earth's surface?
Igneous rock, such as basalt or rhyolite, is formed when magma cools at the Earth's surface.
What is example of igneous rock?
Basalt and pumice.
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 kind of rocks are formed when the magma cools on the earth's surface?
Extrusive igneous rocks such as basalt or rhyolite.
What has a more felsic composition rhyolite or basalt?
Rhyolite has a more felsic composition than basalt.
Does rhyolite or basalt have more silica in it?
rhyolite
What igneous rocks cool above ground?
Igneous rocks that cool above ground are called extrusive or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks form when magma erupts onto the Earth's surface and cools rapidly.
What are the main magma rocks?
Felsic, high in silica. Mafic, low in silica. Intrusive, those formed underground. Extrusive, those formed above ground.
What are rocks that form as a resutlt of cooling magma?
Rocks that form as a result of cooling magma are igneous rocks. They can be classified as intrusive rocks (cooled slowly beneath the Earth's surface) or extrusive rocks (cooled quickly at the Earth's surface). Examples include basalt, granite, and rhyolite.
What are the magma types in order of decreasing viscosity?
Most viscous Felsic magma i.e. rhyolite Intermediate magma i.e. andersite Mafic magma i.e. Basalt Ultramafic magma i.e. Komatiite Least viscous
What rock is formed when magama cools at the earth's surface?
Igneous rock, such as basalt or rhyolite, is formed when magma cools at the Earth's surface.
What is example of igneous rock?
Basalt and pumice.
What type of magma is found on composite volcano?
The average composition of magma in a composite volcano is andesitic. Composite volcanoes are highly variable though. They can erupt anything from basalt to rhyolite.
What has a higher density rhyolite or basalt?
Basalt has a higher density than rhyolite. This is because basalt is a mafic rock with higher concentrations of iron and magnesium, which increases its density compared to rhyolite, which is a felsic rock with lower concentrations of these heavy elements.
