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.
Mafic lava is less viscous(runnier) than felsic lava due to a lower silica content. This causes non-violent eruptions such as in the Hawaiian Islands. Mafic lava tends to be associated more with interplate volcanism and mid-ocean ridges and produces the rock type known as basalt. (The ocean floor is made of basalt.) Felsic lava is mainly found at convergent zones (areas of colliding plates) and has a high silica and water content which causes the lava to be highly viscous and causes very violent eruptions. This lava produces rhyolite and andesitic rocks. The color of the rocks formed by magmas is a consequence of its composition, mafic magmas are dark colored (Mg-Fe) and felsic magmas are light colored (Feldspars-Si).
Granite and grandiorite are two felsic rocks but I'm seeing that some people cosider granite mafic.
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.
No. The terms mafic and felsic apply to igneous rocks. Limestone is a sedimentary/biochemical rock and so cannot be said to be mafic, felsic, or intermediate.
Silica content increases from mafic to felsic, and Mg and Fe content decreases. These differences affect things such as viscosity, density and colour. Felsic magmas are the most viscous and least dense, and felsic rocks are the lightest in colour.
There are many different types of ignoues rock, but as a general description, mafic, felsic and intermediate rocks are formd from basaltic, granitic, and andesitic magmas respectively.
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.
First of all there is no such thing as a mafic or a felsic "mineral". There can be mafic and felsic rocks.Mafic rocks have a high magnesium and iron content.Felsic rocks enriched with lighter elements such as oxygen and silicon.

Olivine is a mafic mineral. It is most abundant in ultramafic rocks.

Mafic rocks, such as those found in the oceanic crust, are more dense than the felsic rocks found in the continental crust.

Neither. The terms mafic and felsic refer to the composition of igneous rocks, which are dominated by silicate minerals. Marble is a metamorphic rock composed of carbonate minerals. The terms mafic and felsic do no apply to it.
Felsic rocks have 0-15% mafic crystals, while mafic rocks have 46-85% mafic crystals.
