Basaltic lava flows much faster than ryholitic lava.
What else can I help you with?
What has a more felsic composition rhyolite or basalt?
Rhyolite has a more felsic composition than basalt.
Does rhyolite or basalt have more silica in it?
rhyolite
Do basalt and rhyolite form magma?
No. Both basalt and rhyolite are formed from molten rock erupts from a volcano.
What has a higher density rhyolite or basalt?
Basalt has a higher density than rhyolite. This is because basalt is a mafic rock with higher concentrations of iron and magnesium, which increases its density compared to rhyolite, which is a felsic rock with lower concentrations of these heavy elements.
Which rock is most felsic out of rhyolite andesite and 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.
Does rhyolite have a more mafic composition than basalt?
Rhyolite is not a mafic rock, but a felsic rock, high in silicates, and similar to granite in composition.
Which volcanic rock has the highest level of silicon dioxide rhyolite or basalt?
Rhyolite.
What has a lighter color rhyolite or 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.
Which has a lighter color rhiolite or basalt?
rhyolite
What rock has a lower density basalt or rhyolite?
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.
What has a lower density rhyolite or basalt?
Ryholite due to the reason that this rock is made up of lighter elements than that of Basalt
Which has a greater percentage of biotite in it rhyolite or basalt?
Rhyolite typically has a greater percentage of biotite compared to basalt. This is because rhyolite is a silica-rich volcanic rock that contains more biotite, a mica mineral, which forms in silica-rich environments. Basalt, on the other hand, is a silica-poor volcanic rock that generally contains lower amounts of biotite.
