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.
What are intermediate rocks?
are a mixture of both mafic and felsic rocks
Why are mafic rocks denser than felsic rocks?

Granite and grandiorite are two felsic rocks but I'm seeing that some people cosider granite mafic.
