Frothy volcanic rock formed by expanding?
Pumice is a frothy volcanic rock formed by the expansion of gas during volcanic eruptions, creating a lightweight and porous material. Its unique texture and low density allow it to float on water. Pumice is commonly used in cosmetics, construction materials, and as an abrasive in various industrial processes.
What are some igneous rocks other than granite basalt pumice rhyolite and obsidian?
Other intrusive igneous rocks include gabbro, diorite, syenite, monzonite, granodiorite, monzodiorite, anorthosite, troctolite, peridotite, and pyroxeneite. Extrusive igneous rocks include dacite, andesite, phonolite, and trachyte when classified by composition, and tuff, and scoria in terms of texture.
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
How does the texture of gabbro compare to obsidian?
Both are made from volcanic rock. Pumice forms when lava cools very quickly and still has pockets of air trapped inside. This make the rock very lightweight and porous -- it can even float on water! Obsidian also forms when lava is quickly cooled, but it does not have trapped air pockets inside. It looks like glass and is rather brittle, but makes an excellent material for sharp cutting implements.
Pumice is a volcanic rock that floats Its density is?
With out knowing further knowledge about the rock it is unable to determine the exact density. However, since the rock floats, presumably in water, the density must be less then 1.00g/L.
What kind of texture do pumice have?
A frothy texture.
What is example of igneous rock?
Basalt and pumice.
What are 12 types of igneous rocks?
diorite,gabbro,granite,obsidean,pumice,rhyolite,andesite
What extrusive rock has the lowest density?
The extrusive rock with the lowest density is pumice. Pumice is a volcanic rock characterized by its light weight and porous texture, formed from lava that cools quickly and traps gas bubbles. This unique formation gives pumice its low density, allowing it to float on water. Its lightweight properties make it useful in various applications, including as an abrasive and in horticulture.
What are some exaples of igneuos rocks?
basalt, granite, rhyolite, andesite, gabbro, obsidian, scoria, pumice.
What type of rock can be changed into igneous rock?
obsidian,basalt,granite,pumice,tuff,diorite,gabbro,andesite,ect
What texture is a pumice?
Pumice is a volcanic rock that is so full of gas bubbles that is it very light, and rough surfaced.

What is the density of 1.3kg of pumice rock?
The density of pumice rock can vary, but on average it is around 0.25-0.55 g/cm^3. To find the density of 1.3kg of pumice rock, you would need to know the volume of the pumice rock. By dividing the mass (1.3kg) by the volume, you can calculate the density.
