The air and gases escape from the lava as it cools. This makes the little holes that you see. The rock is called 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
Does igneous rocks absorb water?
igneous rocks do absorb water because of all the pores ,cracks, and holes in them. The holes will absorb the water and the water will get trapped in the rock there for igneous rocks do absorb water.
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 are 3 types of ingeous rocks?
Igneous rock is any rock made by the cooling of magma or lava. Igneous rocks come with or without observable crystals that are not in layers or with or without air holes or glasslike. Examples of Igneous rocks are granite, pumice, basalt and apache tears obsidian.
What does igneous rock looks like?
Their are a variety of types of igneous rock. The colors vary from a palish yellow in some types to a dark black.

What causes igneous rocks to become magma?
Cooling to a solid.
When molten rocks cools what rocks form?
igneous rocks
What are two ways you could identify igneous rock?
When it has holes and small rocks inside the rock

What causes sedimentary or igneous rocks to turn into metamorphic rock?
Heat and Pressure.
What causes igneous rocks to get darker?
Chemical composition. Especially when Basic\Mafic.
What causes sedimentary and igneous rocks to change?
by melting and cooling
What does igneous rock looks like?

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.
