What else can I help you with?
Is pumice a mineral?
Pumice is a textural term for a volcanic rock that is a solidified frothy lava typically created when super-heated, highly pressurized rock is violently ejected from a volcano
Is pumice a metamorphic rock?
No, pumice is not a metamorphic rock. It is actually a type of igneous rock that forms from volcanic eruptions when frothy lava cools rapidly and traps gas bubbles inside, resulting in its characteristic porous texture. Metamorphic rocks are formed through the transformation of existing rocks under heat and pressure.
What is the streak of pumice?
Pumice forms when frothy lava cools rapidly, trapping gas bubbles within the rock. This gives pumice its characteristic streaks or veins, which are typically lighter or darker in color than the rest of the rock. The streaks in pumice can vary depending on the mineral and chemical composition of the magma from which it formed.
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 pumice a mineral?

Is pumice a metamorphic rock?
No, pumice is not a metamorphic rock. It is actually a type of igneous rock that forms from volcanic eruptions when frothy lava cools rapidly and traps gas bubbles inside, resulting in its characteristic porous texture. Metamorphic rocks are formed through the transformation of existing rocks under heat and pressure.
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.
How could you distinguish pumice and granite?
Granite is a dense, non-porous rock with visible mineral grains. Pumice is a light rock filled with holes left by gas bubbles and generally no visible grains.
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.
What is the streak of pumice?
Pumice forms when frothy lava cools rapidly, trapping gas bubbles within the rock. This gives pumice its characteristic streaks or veins, which are typically lighter or darker in color than the rest of the rock. The streaks in pumice can vary depending on the mineral and chemical composition of the magma from which it formed.
Which rock has large mineral grains granite obsidian basalt or 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.
When you rub a pumice rock on a streak plate what color is left on the streak plate?
The streak left on the streak plate by rubbing a pumice rock usually appears white or colorless. This is because pumice is a light-colored rock composed of volcanic glass with a frothy texture due to gas bubbles trapped in the rock, causing it to create a light streak when rubbed on a streak plate.
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.
What metamorphic rock can float?
Pumice.
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.
What type of rock is pumice?
It is an igneous (volcanic rock).
