Volcanic rocks with gas bubbles are called vesicular. This, however, is a descriptive term rather than an actual rock types. Some vesicular volcanic rocks include pumice, scoria, and vesicular basalt.

What are holes in a rock that result from rapid cooling called?
Vesicles.
What is the mafic rock that is full of holes and made of dense materials is?
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.
Why do holes form in some extrusive rock?
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 type of rock is river rock is it sedimentary metaphoric or igneious?
River rock can be composed of any rock type, or any combination of rock types.
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.
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.
What is the type of rock fragment that contains holes and tunnels left by escaping gases called?
These are known as Pumice stone.
What type of rock is looked for when seeking deposits of natural gas?
Sedimentary Rocks. When holes are drilled through the rock into these spaces, natural gas is obtained for out usage
If a rock has many small holes what is it?
It is possibly a volcanic rock, for example scoria
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.
What is the name for the natural holes found in rock?
Craters
What is a volcanic rock with many air holes?
Pumice
Is Scoria rock igneous?
Yes,Scoria (a type of Basalt) Basalt is a dark-colored rock that formed as lava cooled and hardened. Scoria is a type of basalt that's full of bubble holes. The bubbles formed as the lava was blasted out of a volcano, and were trapped as the lava cooled and hardened.
What are two ways you could identify igneous rock?
When it has holes and small rocks inside the rock
How does melted rock reaches earth's surface?
From holes in the ground that push up the melted rock
Where did ancient Egypt get most of its gold?
The Egyptians mined large blocks of rock by drilling holes in a line in a rock's surface. The holes were filled with wedges of wood. Wetting the wooden wedges caused them to expand, and after a period of time, the rock split along the line of the drilled holes.
