What else can I help you with?
Does obsidian float?
No, not unless it is somehow shaped into a form that displaces less water than it's mass. Obsidian is volcanic glass, glass is much denser than water, therefore sinks.
What type of rock will float on water?
Any with a density less than the fluid into which it is placed. Pumice is a volcanic rock that will sometimes float on water.pumice
Is obsidian a metamorphic rock?
Obsidian is an igneous rock.So the answer is YES.
In order to maintain the shine of an obsidian rock how can you cut it to show the colors?
To maintain the shine of an obsidian rock, you can polish it using a soft cloth and a commercial jewelry polish. To reveal the colors within the obsidian, you can cut it using a lapidary saw or water-cooled tile saw. Be sure to wear appropriate safety gear when cutting the rock.
What igneous rock has no visible crystals?
Granite is a coarse grained igneous rock without Pyroxene.
Does obsidian rock float?
No, obsidian rock does not float as it is a dense and heavy igneous rock formed from cooled lava. Its high density causes it to sink in water.
Can obsidian float on water?
Obsidian cannot float on water. It has a specific gravity about 2.5, meaning it is about two and one-half times as heavy as water and will sink if immersed.
How can you determined if a rock can float in water?
You can determine if a rock can float by comparing its density to the density of water. If the rock is denser than water, it will sink. If the rock is less dense than water, it will float. This can be tested by placing the rock in a container filled with water and observing its behavior.
What type of rock cannot float on water?
Virtually all types of rock will sink in water. The only rock that can float on water is pumice.
Where does obsidian rock cools down?
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.
Is obsidian metamorphic igneous or sedimentary?
Obsidian is an igneous rock.
What does rock group does obsidian belong to?
Obsidian is in the Igneous rock group.
Does obsidian sink or float?
Obsidian typically sinks in water due to its high density. It is a type of volcanic glass that forms from the rapid cooling of lava, creating a material denser than water.
Does a shale rock float in water?
no
What is the hardst mineral on Earth?
Obsidian, the rock that occurs when lava and water mix.
Is obsidian extrusive rock?
No. Obsidian is volcanic glass. Glass is amorphous and thus noncrystalline.
Does obsidian float?
No, not unless it is somehow shaped into a form that displaces less water than it's mass. Obsidian is volcanic glass, glass is much denser than water, therefore sinks.
