Are rocks composed of minerals?
Rocks are for the most part composed of one or more minerals. Obsidian is an exception because the mineral solution (lava) did not have time to form mineral crystals because of very rapid cooling. However, most obsidian will still contain some mineral crystals or crystal inclusions.
What are some rocks that aren't a mineral?
Rocks are not minerals. They are composed on one or more minerals. For example granite is composed primarily of the minerals quartz, potassium feldspar, and albite. There are some rocks, however, that are composed of substances that aren't minerals. Examples include coal, which is mostly organic, and glassy rocks such as obsidian, pumice, and some varieties of tuff.
How do obsidian rocks get from being minerals to a rock?
Obsidian rocks are formed from minerals underground in places like the earth's core and volcanoes. They require heat and pressure, which squishes the minerals together to form a rock. There is air trapped inside the rock when it is formed, which creates the bubbles, or "holes" inside the rock if you look at one. When I find out more about it, then I will let you know more about it.
What kind of rocks and minerals are found in volcanoes?
Volcanoes contain a variety of rocks and minerals such as basalt, andesite, rhyolite, obsidian, pumice, and granite. Volcanic rocks are typically rich in silicate minerals like quartz, feldspar, and olivine, with varying amounts of volcanic glass and pyroclastic material. Minerals like sulfur, pyrite, and magnetite can also be found in volcanic environments.
