Yes, obsidian is found near volcanic mountains.
Obsidian is an glassy, extrusive, igneous rock that is found in areas that have experienced rhyolitic eruptions. Obsidian is formed when the rhyolitic lava comes into contact with water. This quick-cooling results in the glassy texture of obsidian.
Obsidian is an extrusive igneous rock. Volcanic in origin, it is very common in recent lava flows. Obsidian is primarily made of glass. Obsidian is amorphous, lacking any crystal structure found in gemstones. For more details, try asking the question - "What is obsidian"
Yes, obsidian is an igneous rock. It forms when molten lava cools rapidly and solidifies without crystal formation, resulting in a smooth, glassy texture. Obsidian is commonly found near volcanic areas.
No, obsidian is also called 'volcanic glass,' since it is a product of cooled lava. Since there are no volcanoes in Louisiana there will not be any natural obsidian.
Obsidian is an igneous rock.
Yes, obsidian rock has been found on the Moon. During the Apollo missions, samples collected included volcanic glass, which is essentially obsidian formed from rapidly cooled lava. This indicates that volcanic activity occurred on the Moon in the past, producing materials similar to those found on Earth.
Obsidian is in the Igneous rock group.
No. Obsidian is volcanic glass. Glass is amorphous and thus noncrystalline.
Obsidian is molten silica (read sand) which has cooled rapidly after a volcanic eruption into brittle glass and is the reason why it chips easily into blades. Iron and magnesium give obsidian its dark color.
Obsidian is an extrusive felsic igneous rock.
Volcanic rock.
No. Obsidian is just one of many types of volcanic rock.
