As compared to mafic igneous rocks do all felsic igneous rocks cool and solidify more slowly?
No. Whether igneous rocks cool quickly or slowly is more dependent on whether the rock is intrusive or extrusive than whether it is mafic or felsic. Because it is so viscous it is often difficult for felsic magma to erupt, and so it is more likely to be intrusive and thus cool slowly. When felsic magma is involved in an eruption, it often erupts explosively. Some of the molten rock ejected cools extremely rapidly, forming volcanic glass.
What else can I help you with?
Is felsic an intrusive or extrusive igneous rock?
It can be either. "Felsic" is not a specific type of rock but a general description of an ingeous rock's composition indicating high levels of silica and alkali feldspars.
What are four felsic igneous rocks?
Four felsic igneous rocks include granite, rhyolite, pegmatite, and dacite. These rocks are characterized by their light color and high silica content, making them rich in minerals like quartz, feldspar, and muscovite. They typically form from magma that has cooled and solidified slowly underground.
Which igneous rocks form below earth's surface?
Igneous rocks that form below the Earth's surface are called intrusive igneous rocks. Examples include granite, diorite, and gabbro. These rocks cool and solidify slowly, allowing large crystals to form.
Why are lava flows finer grained than intrusive igneous rocks?
Lava flows cool rapidly compared to the cooling of rocks underground. The slower cooling time of intrusive igneous rocks allows larger crystal formation. Generally, the more cooling time, the larger the crystals.
What forms in earths crust when molten material reaches the surface?
When molten material reaches the surface of the Earth, it can solidify into different forms depending on the speed of cooling. If it cools quickly, it forms extrusive igneous rocks like basalt. If it cools slowly underground, it forms intrusive igneous rocks like granite.
Do granite igneous rock form quickly or slowly?
Granite is the result of slow cooling processes of felsic magmas.
Is felsic an intrusive or extrusive igneous rock?

Why do igneous rock that solidify underground cools so slowly?
They are insulated by the surrounding rock and are in close proximity or part of a hot, molten, or partially molten igneous intrusion.
What are four felsic igneous rocks?
Four felsic igneous rocks include granite, rhyolite, pegmatite, and dacite. These rocks are characterized by their light color and high silica content, making them rich in minerals like quartz, feldspar, and muscovite. They typically form from magma that has cooled and solidified slowly underground.
Which two types of rocks cooled slowly?
Intrusive igneous and metamorphic. Intrusive igneous rocks are those that solidify underground. Metamorphic rocks are those that are deep underground and subjected to intense heat and pressure, but remain a solid.
When melted rock cools it forms?
When melted rock cools, it forms igneous rock. The process of cooling allows the molten rock, also known as magma or lava, to solidify and form crystals. Igneous rocks can have different textures and compositions depending on how quickly or slowly the rock cools.
Does dioriote cool quickly or slowley?
Diorite cools relatively slowly compared to volcanic rocks such as basalt. Diorite is an intrusive igneous rock, meaning it forms beneath the Earth's surface, allowing it more time to cool and solidify. This slow cooling process helps diorite develop its characteristic coarse-grained texture.
Which igneous rocks form below earth's surface?
Igneous rocks that form below the Earth's surface are called intrusive igneous rocks. Examples include granite, diorite, and gabbro. These rocks cool and solidify slowly, allowing large crystals to form.
Is granite igneous or metamorphic?
igneous. Made from slowly cooling magma. :)
What is igneous rock that cools slowly beneath the ground?
Intrusive Igneous Rock.
Is granite metamorphic sedimentary or igneous?
igneous. Made from slowly cooling magma. :)
What is igneous rocks that form below Eart's surface are called?
Igneous rocks that form below the Earth's surface are called intrusive or plutonic rocks. These rocks cool and solidify slowly, allowing large mineral crystals to form. Examples include granite and diorite.
