What else can I help you with?
Is this true or false pumice is a rock that has many tiny holes where gases were trapped?
true
Which stone can not sink in water?
Pumice does not sink in water. This is because pumice, type of lava, forms by the rapid cooling of lava that contains significant amounts of dissolved gasses. When the lava erupts the sudden decrease in confining pressure on the lava allows this gas to come out of solution. This makes lots of bubbles form very rapidly (the lava is essentially a foam). As the lava cools very rapidly the bubbles are trapped in the solidifying material forming the hollow void spaces known as vesicles which result in pumices low density.
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 an example of vesicular rocks?
An example of vesicular rock is pumice, which is a light-colored igneous rock that forms from volcanic eruptions. Pumice contains many small cavities (vesicles) caused by trapped gas bubbles in the molten rock that rapidly cooled and solidified.
Why pumice is the only rock that floats?
Pumice is the only rock that floats because it has a low density due to the many air pockets trapped within its structure. These air pockets are formed during the cooling of volcanic lava, creating a porous material that is less dense than water. This unique property allows pumice to float on the surface of water.

true
What is a volcanic rock with many air holes?
Pumice
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 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.

Igneous feature would you find rocks with a vesicular texture?
You would typically find rocks with vesicular texture in igneous features such as volcanic necks, lava flows, and volcanic ash deposits. Vesicles are voids or cavities left behind by gas bubbles trapped in the cooling magma.
Why pumice is the only rock that floats?
Pumice is the only rock that floats because it has a low density due to the many air pockets trapped within its structure. These air pockets are formed during the cooling of volcanic lava, creating a porous material that is less dense than water. This unique property allows pumice to float on the surface of water.
Many extrusive volcanic rocks contain holes which have formed from?
Many extrusive volcanic rocks contain holes, or vesicles, which have formed from gases trapped in the magma during eruption. As the lava cools and solidifies, these gases escape, leaving behind the characteristic holes in the rock.
