Pumice is an igneous rock full of tiny holes. Explain how these holes were produced?

- how the holes may get there is from the hot lava or magma and since it is very hot it may cause the holes i am not to sure though about my answer.
- When rocks are heated to melting point, bubbles of gas can get trapped in them. When the rock cools, the gas is left as a hole. Volcanic rock is chock full of holes.

What causes holes in igneous rock?
Fast cooling lava can trap air bubbles, creating a bubbly or vesicular texture.
What is the mafic rock that is full of holes and made of dense materials is?
Pumice
Why does pumice float?
Pumice is full of holes called vesicles formed from gasses escaping the molten rock. The holes greatly reduce its density.
Why doesn't granite have air holes like pumice and scoria?
Pumice and scoria are volcanic rock. They form form the lava the erupts from the volcano and contains bubbles from gasses. These bubbles cause the cavities you're calling air holes.
What are facts about Pumice?
Pumice is a volcanic rock that forms when a volcano ejects "foamy" lava. The gas bubbles remain in place after the rock solidifies. One of Pumice's most notable characteristics is that it will float in water.
What igneous rock has tiny holes that look like a sponge?
pumice
Why does pumice have a lower density than other igneous rocks?
It is a glassy igneous rock, so there are holes in it. The holes make the rock less dense than other igneous rocks that are Not glassy.
What is a lightweight igneous rock that is full of tiny holes?
I'd say pumice is the closest to your description.
What is texture in rocks?
* Vesicular rock texture is generally displayed in extrusive igneous rocks which contain many vesicles of trapped air, such as pumice or scoria. * Igneous rocks containing holes which were produced as gases escaped from the upper part of lava flow.
What is vesicular texture in rock?
* Vesicular rock texture is generally displayed in extrusive igneous rocks which contain many vesicles of trapped air, such as pumice or scoria. * Igneous rocks containing holes which were produced as gases escaped from the upper part of lava flow.
What do you called an igneous rock that floats on water due to the presence of many gas bubble holes.?
Pumice is such a rock.
What is an igneous rock that floats on water due to the presence of many gas bubble holes.?
The rock comes from a volcano and is known as pumice.
What causes air holes in igneous rocks?
Igneous rocks form when lava or magma cools.But when cooling there are air bubbles that are trapped in the lava.Prime examples of this event are found in pumice and scoria
What causes igneous rocks to have holes?
The air and gases escape from the lava as it cools. This makes the little holes that you see. The rock is called pumice.
Where does pumice form?
Vesicular solidified lava, an extrusive igneous rock.
What is a igneous rock made with volcanic rock with many air holes light enough to float on water?
That is a type of rock called pumice.
What is made out of pumice?
Pumice is a form of volcanic glass that is rich in silica. There are also fairly high amounts of aluminum oxide, sodium oxide, and potassium oxide. The holes or vesicles are the remnants of gas bubbles that formed when the pumice was still molten.
