One kind of volcanic glass that has holes caused by pockets of gas?
Scoria is the best answer, but under some circumstances, probably pumice
What is the type of rock fragment that contains holes and tunnels left by escaping gases called?
These are known as Pumice stone.
What is pummice?
Pumice is a type of extrusive igneous rock, formed from high silica lava which is explosively erupted from volcanoes. If the amount of trapped gases in the lava is high, vesicular pumice will be formed; thin walled, high in trapped gas pockets, and able to float on water.
What causes the frothy appeance of pumice and scoria?
Frothy rocks are caused by violent volcanic eruptions shoot out lava filled with gases. the lava cools quickly, while it is still in the air, and reaps the gases inside. rocks that form this ay are full of holes . two examples of these rocks are pumice and scoria
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
Why do pumice and scoria have holes in them?
Pumice is acutally a volcanic rock. after the volcano erupts, the lava cools. It's mixed with water and cools very fast, which causes the water and air in the lava to be expelled quickly, causing holes.
Why does pumice float?
Pumice is full of holes called vesicles formed from gasses escaping the molten rock. The holes greatly reduce its density.

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 was formed from lava that was cooled with hot gases trapped inside causing it to be filled with air holes?
The rock will have little 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.

Why does pumice have such a low density?
Because it is full of holes and air spaces. This is because it forms while bubbles of gas are trapped in quick-cooling lava.
Does pumice really need holes to be pumice?
Yes. Pumice is defined as being highly vesicular.
