Obsidian can be intrusive when felsic lava cools on the edges of a deck. Obsidian consists of approximately 70% or more of the silicone (silicone dioxide) that has been uncristallised. It is like granite and rhyolite, which were also initially frozen, chemically. As obsidian is not mineral ...
Why is coal an organic sedimentary rock? Why is density important to mineralogy? Why are silicate minerals important? How does weathering affect sedimentary rocks? Why does basaltic magma have the lowest viscosity? Why does rhyolite have smaller crystals than granite?
The term extrusive simply refers to any rock that was created when magma reached the surface of the Earth and cooled. Since it extruded from within our planet, it is broadly referred to as extrusive.Answer and Explanation: Extrusive rocks have air pockets because in the process of cooling, ...
Why does rhyolite have smaller crystals than granite? How is sedimentary rock dependent on minerals? How does weathering affect sedimentary rocks? Why are sedimentary rocks important? Why are igneous rocks important to absolute dating? Why are sedimentary rocks the only rock type to...
Why are basalt and granite important igneous rocks? Why is glass not a mineral? Why are terrestrial planets made of rock? Why are fossils never found in igneous rocks? Why does obsidian contain few or no mineral grains? Why do minerals have different properties? Why do igneous rocks have ho...
Why does rhyolite have smaller crystals than granite? Why are metamorphic rocks formed by contact metamorphism? Explain why hornblende is more common in igneous rocks while tremolite is almost exclusively found in metamorphic rocks. Why do intrusive rocks have a coarse texture? Why are chemical radi...
