Is granite a glassy igneous rock?
No, granite is a coarse-grained igneous rock that is made up of minerals like quartz, feldspar, and mica. Glassy igneous rocks, like obsidian, form when molten lava cools quickly on the surface, resulting in a smooth, glass-like texture.
Is orbicular rhyolite a metamorphic rock?
No, orbicular rhyolite is not a metamorphic rock. It is a type of igneous rock that forms from the cooling of silica-rich magma. Orbicular rhyolite is characterized by its spherical clumps of minerals, giving it a distinctive appearance.
