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.

This type of magma is thick moves slowly and does not flow well?
felsic
What rock weathers very slowly?
igneous rock
Does an Extrusive Rock cool slowly?
Cools quickly, relative to intrusive igneous rock which cools slowly underground.
What do the large crystals in this igneous rock tell about the rock?
That it cooled very slowly.
What do the large crystals in igneous rocks tell about the rock?
That it cooled very slowly.
Do granite igneous rock form quickly or slowly?
Granite is the result of slow cooling processes of felsic magmas.
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.
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.
This type of magma is thick moves slowly and does not flow well?
felsic
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. :)
Which kind of igneous rocks form when magma cool slowly?
intrusive igneous rock
Do rocks that cool slowly from magma contain more crystals?
No. They would contain fewer, but larger mineral crystals when compared to igneous rocks which have cooled quickly from lava or magma.
What is the texture of igneous rock?
Phaneritic is the texture of igneous rocks. These types of rocks crystallized slowly.
What igneous rocks that form from magna cools slowly?
Intrusive igneous rocks, like granite.
What rock weathers very slowly?
igneous rock
