Where does pumice form?
Vesicular solidified lava, an extrusive igneous rock.
You find a volcanic rock that is fairly smooth and only has a few small holes made when gas and water vapor escaped as the rock cooled you know that the rock can be classified as?
The rock described would be classified as an extrusive mafic igneous rock.
Does an ingneous rock contain many small holes?
Yes, It is rough and contains many small holes. Igneous rock is formed by cooling of magma/or lava.
Why are black holes round?
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
Are volcanic rocks heavy?
They are usually about the same density as non-volcanic rocks. The one exception is pumice, which is so full of holes that it is less dense than water.
Why do holes form in extrusive rocks?
the holes in extrusive igneous rocks (lava) are called vesicles. They are formed by gas escaping from the rock when molten, leaving bubbles in the melt which which may be preserved when the lava solidifies

What can be inferred about volcanic rocks with gas holes in them?
It can be at least inferred that the rocks cooled quickly enough to retain the shape of the gas bubbles, and that they are therefore extrusive igneous rocks.
Where does pumice form?
Vesicular solidified lava, an extrusive igneous rock.
Why are there holes in igneous rock?
The holes represent the bubbles of trapped and expanding gas that was present in the solidifying lava. They were essentially frozen in place.

Do volcanoes make black holes in the water?
The black holes found in space? No. An underwater volcano or a split in the seafloor can leak magma into the ocean causing it to instantly cool. This is one way islands are formed. So the volcanic stone may be black, but they are not referred to as black holes.
What is a volcanic rock with many air holes?
Pumice
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 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.
Is granite the lightest rock?
no scoria is the lightest it is volcanic and has many holes in
