Pumice is a type of rock that is made up from sand particles.The stones on beaches eroded against each other to produce sand , some sand is dragged out to the middle of the ocean and deposited on the sea bed , animals like fish die and lay here to.
Over hundreds of years more sand has been deposited on top and the weight increase on the layer we spoke about then with the high pressure they form the pumice stone and other stones such as limestone.
What else can I help you with?
Are molten rock and lava the same thing in different places?
Molten rock that has been erupted onto Earth's surface is known as lava. Molten rock within the Earth is known as magma.
How are lava and magma the same?
Lava and magma are both molten rock beneath the Earth's surface. The main difference is that magma is molten rock below the surface, while lava is molten rock that has reached the surface through volcanic eruption.
Why pumice floats while a rock of similar size will sink in the same tank of water?
When pumice is formed - it traps minute amounts of gas in bubbles within the rock itself. This makes it buoyant.
What Magma and lava can both solidify to produce?
They are both the same thing, which is melted rock, which means they solidify to form rock. The only difference between magma and lava is that magma is underground, and lava is not.
Is a stratovolcano the same as composite volcano?
Yes, a stratovolcano is the same as a composite volcano. They both refer to volcanoes composed of layers of hardened lava, pumice, and volcanic ash. These volcanoes are known for their steep sides and explosive eruptions.
What buried the town of Pompeii lava or magma?
Neither. The town of Pompeii was buried by pumice which over the years hardened. Lava and magma are virtually the same thing. Magma is the molten material in the earth. Igneous rock is formed from it when it cools. Lava is a liquid rock which also can solidify into lava stone. Unless you're a vulcanologist, and have to be scientifically picky, consider lava as an "outside" liquid rock and magma as an "inside" liquid rock.Neither.

Are molten rock and lava the same thing in different places?
Molten rock that has been erupted onto Earth's surface is known as lava. Molten rock within the Earth is known as magma.
Is molten rock and lava flow the same thing?
Not exactly. Molten rock is called either magma or lava depending on whether it is underground or above ground. When lava flows on the surface like a river or flood it is called a lava flows, but lava is not always flowing downhill. Sometimes it can collect in a pool called a lava lake, or be flung into the air in a lava fountain.
Are lava and magma the same thing?
Lava is simply magma that has reached the surface.
How are lava and magma the same?
Lava and magma are both molten rock beneath the Earth's surface. The main difference is that magma is molten rock below the surface, while lava is molten rock that has reached the surface through volcanic eruption.
Why pumice floats while a rock of similar size will sink in the same tank of water?
When pumice is formed - it traps minute amounts of gas in bubbles within the rock itself. This makes it buoyant.
Is hot lava the same as molten rock?
yes
What Magma and lava can both solidify to produce?

How are basalt and pumice the same?
Other than that they are both types of rock, very little. They have very different methods of formation and mineral composition. Basalt is produced from mafic lava flows, and shale is a product of sedimentary rock processes.
Is lava a sedimentary rock or igneous?
The common usage of "lava rock" in the USA refers to a black rock with a number of visible bubbles or air pockets that is formed from cooled lava on the surface. Although lava rock is an igneous rock, it is not the same as the definition for the word igneous, which can also include igneous rocks which have solidified from magma below the surface.
Are soap and pumice made of the same material?
no because pumice is a dead sea sponge that exfoliates the skin and soap is for cleaning the skin not exfoliating Answer:Soap is saponified fat or oil that removes oil based dirt by providing both hydrophilic and oleophylic sites on a single molecule. Pumice is essentially volcanic ash. It is an abrasive in its own right but may be added to soap to physically remove heavy grime by abrasion.
