Rhyolite is silica-rich, containing over 70% silica. It is an extrusive igneous rock with a fine-grained texture that forms from the rapid cooling of magma rich in silica content.
The mantle primarily contains mafic magma, which is rich in iron and magnesium. Felsic magma, which is rich in silica, is more commonly found in areas associated with continental crust or in volcanic arcs.
The igneous rock you are referring to is basalt. It is a fine-grained, dense, and dark-colored rock that forms from low-silica magma rich in iron and magnesium.
Acidic lava is very viscous, and thus will harden and block the vent. The magma will force its way out through the vent and create a violent explosion.
Rhyolitic magma typically forms beneath continental crust due to high silica content and low temperature. The silica-rich composition leads to viscous magma, which is more common in continental settings compared to oceanic crust where magma tends to be more basaltic and less viscous.

Yes. Granite forms when silica-rich magma cools underground.
Silica-rich magma forms in mid-ocean ridges due to partial melting of the upper mantle, as a result of increased temperature and decreased pressure. This magma rises through cracks in the oceanic crust and can eventually erupt at the surface as lava.
