Is a pumice rock a rock or a mineral?
A pumice rock is considered a rock because it is composed of multiple minerals, mainly feldspar and quartz. Minerals are the building blocks of rocks, so pumice is classified as a rock rather than a single mineral.
What is the mineral pumice's hardness on moh's scale?
Pumice has a hardness of about 5 to 6 on the Mohs scale.
What is the hardness of pumice on moh's scale?
Pumice has a hardness of about 6 on the Mohs scale of mineral hardness.
Which rock has large mineral grains granite obsidian basalt or pumice?
Granite has large mineral grains compared to obsidian, basalt, and pumice. Granite is an intrusive igneous rock that forms deep within the Earth's crust, allowing for the growth of large mineral crystals due to slow cooling. Obsidian, basalt, and pumice are extrusive igneous rocks that cool quickly at the Earth's surface, resulting in smaller mineral grains or a glassy texture.
What is an example of a mineral with low specific gravity?
One example of a mineral with low specific gravity is pumice. Pumice is a volcanic rock formed from frothy lava with numerous gas bubbles trapped within its structure, resulting in a low density and specific gravity.
Is a pumice rock a rock or a mineral?

Which mineral has a sponge like appearance?
Pumice
Does pumic have mineral grains?
Pumice does not have grains.
What mineral it used in soil mixes?
The mineral used in soil mix is pumice
What is the mineral pumice's hardness on moh's scale?
Pumice has a hardness of about 5 to 6 on the Mohs scale.
What is the hardness of pumice on moh's scale?
Pumice has a hardness of about 6 on the Mohs scale of mineral hardness.
Is pumice a stone or mineral?
Pumice is a type of extrusive volcanic rock, produced when lava with a very high content of water and gases (together these are called volatiles) is extruded (or thrown out of) a volcano. Pumice is not a mineral because it does not have a definite composition and lacks a crystalline structure.
Which mineral is an abrasive that is used to make stone washed jeans?
Pumice
What has the author John L Burnett written?
John L. Burnett has written: 'Mineral commodity report, diatomite, 1991' -- subject(s): Diatomaceous earth 'Mineral commodity report, pumice and pumicite' -- subject(s): Pumice industry, Pumice, Perlite 'Mineral commodity report diatomite, 1991' -- subject(s): Diatomaceous earth
Is pumice metallic or nonmetallic?
Pumice is a nonmetallic mineral. It is a type of volcanic rock that is formed from the rapid cooling of frothy lava with high gas content, resulting in a lightweight and porous texture.
Is pumice and obsidian exaples of minerals?
Pumice is not a mineral; it is a type of volcanic rock with a frothy texture. Obsidian, on the other hand, is a naturally occurring volcanic glass and is considered a mineraloid rather than a true mineral because it lacks a crystalline structure.
Which rock has large mineral grains granite obsidian basalt or pumice?
Granite has large mineral grains compared to obsidian, basalt, and pumice. Granite is an intrusive igneous rock that forms deep within the Earth's crust, allowing for the growth of large mineral crystals due to slow cooling.
