basalt
Rhyolite generally has a lighter color compared to basalt. Rhyolite is typically light gray, pink, or cream, while basalt is usually dark gray to black. This difference in color is primarily due to their mineral compositions, with rhyolite containing higher amounts of silica.
rhyolite
Basalt typically contains a greater percentage of biotite compared to rhyolite. Rhyolite is a silica-rich volcanic rock that generally has a lower abundance of mafic minerals like biotite, while basalt, being more mafic, often includes higher amounts of biotite and other ferromagnesian minerals. Therefore, basalt has a higher percentage of biotite than rhyolite.
No. Both basalt and rhyolite are formed from molten rock erupts from a volcano.
Basalt and pumice.
Basalt has a lower density compared to rhyolite. Basalt is a mafic rock with higher iron and magnesium content, which makes it denser. Rhyolite, being a felsic rock with higher silica content, is less dense.
Ryholite due to the reason that this rock is made up of lighter elements than that of Basalt
Rhyolite is the most felsic rock out of rhyolite, andesite, and basalt. Felsic rocks have a higher silica content and are associated with continental crust. Rhyolite is typically light in color and has a high silica content, making it more felsic compared to andesite and basalt.

Rhyolite is not a mafic rock, but a felsic rock, high in silicates, and similar to granite in composition.
Rhyolite.
rhyolite
Basalt and gabbro have higher chemical weathering rates than rhyolite and granite because they contain more ferromagnesian minerals like olivine and pyroxene that are more susceptible to chemical weathering compared to the quartz-rich minerals in rhyolite and granite. This makes basalt and gabbro more prone to breakdown and alteration when exposed to weathering agents like water and acids.
