Why are felsic rocks melted by mafic magmas but mafic rocks are not melted by felsic magmas?
Felsic rocks have a lower melting point than mafic rocks and felsic magma has a lower temperature. In other words, felsic magma is not hot enough to melt mafic rock while mafic magma is hot enough to melt felsic rock.
Which cools faster mafic or felsic rocks?
mafic because it is-dark colored. Ultramafic - no light colored mineral which means it it attracts most heat from a volcano taking it longer to cool down from the lighter, in between substance known as felsic :D
Are felsic rocks usually intrusive or extrusive?
Most felsic rocks, though not all, are intrusive.
Is pegmatite felsic or mafic?
It is felsic because it is lightly colored. Most rocks that are light are also felsic. The exception is obsidian which is dark and felsic.
What does Lower temperatures cause rocks to?
contract

What does the word felsic?
The word felsic is used to describe igneous rocks that are rich in silica and alkali feldspar. Such rocks tend to be light in color and have a lower density than other igneous rocks.
Light-colored igneous rocks with a lower density than basaltic rocks?
Felsic rocks.
What does the word felsic mean?
Feldspar can be a variety of colors: clear, gray, white, tan, pink, brown, or red.

Why do rocks cool and crystallize?
Not all rocks do cool and crystallize, your question is meaningless.
What rocks are felsic?
Felsic rock are igneous rocks that are rich of quartz, orthoclase and plagioclase minerals. Here is the list of felsic rocks: granites, rhyolites, aplites, and pegmatites.
What minerals are present in felsic rocks and mafic rocks?
Felsic refers to igneous rocks that are relatively high in silica and aluminum. Mafic refers to igneous rocks that are higher in magnesium and iron than felsic rocks.
Are felsic rocks usually intrusive or extrusive?
Most felsic rocks, though not all, are intrusive.
Can Small amounts of water can lower partial melting temperatures in silicate rocks?
The addition of water can lower partial melting temperatures in silicate rocks.
Do sedimentary rocks cool and crystallize?
No, sedimentary rocks are deposited and undergo lithofication over time. Igneous rocks cool and crystallize
Is pegmatite felsic or mafic?
It is felsic because it is lightly colored. Most rocks that are light are also felsic. The exception is obsidian which is dark and felsic.
