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 is the igneous rocks that cool quickly on the surface?
Igneous rocks that cool quickly on the surface are known as extrusive or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks have fine-grained textures due to their rapid cooling process.
Igneous rocks that cool quickly on earth surface are?
Igneous rocks that cool quickly on the Earth's surface are called extrusive or volcanic rocks. Examples include basalt, obsidian, and pumice. These rocks have fine-grained textures due to their rapid cooling.
Igneous rocks that result when lava solidifies are classified as what?
Igneous rocks that result from lava solidifying above ground are classified as extrusive igneous rocks. These rocks cool quickly, leading to small mineral grains and a fine-grained texture. Examples include basalt and rhyolite.
How do rocks change from metamorphic or sedimentary rocks to igneous rocks?
Metamorphic and sedimentary rocks can change into igneous rocks through the process of melting and cooling. When subjected to intense heat and pressure, the rocks can melt and form magma. This magma can then cool and solidify, forming igneous rocks.

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.

What is the difference between the way intrusive and extrusive igneous is formed?
Intrusive igneous rocks cool beneath the crustal surface. Extrusive cool above the surface - pillow lavas cool below the sea but above the crust.
What is the different between extrusive and intrusive rocks?
Intrusive: An intrusive igneous rock is formed from magma undergroundExtrusive: An extrusive igneous rock is formed from lava outside of the volcano.
What kind of lava does composite volcanoes produce AA or pahoehoe?
Usually neither. A'a and pahoehoe lavas are both of mafic composition (rich in iron and magnesium, poor in silica) and form basalt when they cool. Composite volcanoes usually erupt material of intermediate to felsic composition (felsic is rich in alkalis, aluminum, and silica), with lavas cooling into rocks such as andesite, dacite, and rhyolite.
What is the igneous rocks that cool quickly on the surface?
Igneous rocks that cool quickly on the surface are known as extrusive or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks have fine-grained textures due to their rapid cooling process.
What are melted rocks that cool?
igneous rocks
What are rocks that form from the cool lava?
Igneous rocks.
What is the description for igneous rocks?
cool
How quick does extrusive igneous rocks cool?
Intrusive igneous rocks cool slowly. These types of rocks would be located underground having long period of time to cool.
What are Igneous rocks that cool quickly beneath Earth's crust called?
Igneous rocks that cool quickly beneath earth's crust are known as intrusive rocks. These rocks will form from magma which will cool and solidify quickly.
Are igneous rocks the rarest rocks found on earth?
Apples are cool
What are types of extrusive igneous rocks?
Extrusive igneous rocks are igneous rocks that form above earth's surface. They are usually fine-grained due to the rate in which they cool.
