No, magma with a silica content of 50 percent is more felsic, while magma with a silica content of 70 percent is more mafic. Silica content is inversely proportional to magma's mafic or felsic classification.
The three main types of magma are basaltic magma, andesitic magma, and rhyolitic magma. They are classified according to their mineral composition. Basaltic magma is composed of SiO2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na. Andesitic magma is composed of SiO2 55-65 wt%, intermediate. in Fe, Mg, Ca, Na, K. Rhyolitic magma is composed of SiO2 65-75%, low in Fe, Mg, Ca, high in K, Na.
Cooled and solidified magma that rests below the surface becomes intrusive igneous rock. When magma is erupted onto the surface, then cools and solidifies, it becomes extrusive igneous rock. The major rock classification for cooled magma or lava would be IGNEOUS.
If a magma of higher temperature cools down, certain minerals solidify first. Eventually, those minerals that remain liquid at the lowest temperatures solidify the latest. The rock that is then formed is Granite (if it's intrusive), or Rhyolite (if it's extrusive)
That classification is on the basis of there environment of formation.Intrusive form deep into the earth from magma while Extrusive form at the surface from cooling lava flows.
Cognitive Constraints on Compositional Systems was created in 1988.

A Compositional Mixture .
the difference is that the earth's theory is similar to that of a hypotheses , structure and compositional layer of the earth.

Compositional is the adjective of the word composition.

I'm bored... Class sucks. smh...
