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.
are a mixture of both mafic and felsic rocks
Mafic rocks are denser than felsic rocks because they contain heavier compounds, minerals and other materials, they are ferromagnesian in composition.
Wind
greater proportion of silica
Felsic rocks have 0-15% mafic crystals, while mafic rocks have 46-85% mafic crystals.
rocks weather faster in polluted cities
Why do the rocks at the top of a moutain peak weather faster the ones at the bottom
mafic rocks can be made up of orthoclase feldspar and quartz
Santorini volcano has also and mafic rocks.
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.
These rocks are called mafic igneous rocks, such as basalt. == ==
are a mixture of both mafic and felsic rocks
Mafic rocks, such as those found in the oceanic crust, are more dense than the felsic rocks found in the continental crust.
Mafic rocks are denser than felsic rocks because they contain heavier compounds, minerals and other materials, they are ferromagnesian in composition.

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.
