the lava bubbles up and some of the rock cools while there is a bubble and makes a little gap in side.

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
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
Are igneous rocks made up of igneous rocks?
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.
What do you call rocks that have been formed from the hot molten material within the earth's crust that has cooled and hardened?
Igneous rocks are formed by the solidification of molten materials.
Are sedimentary rocks are harder than igneous rocks?
No, igneous rocks are harder than sedimentary rocks on average.
Do any igneous rocks have gas bubbles or gaps?
jellybeans are cool
What kind of igneous rocks that formed a bubbles when putting a vinegar?
limestone
Why do some igneous rocks have bubbles or pores and are these rocks intrusive or extrusive?
The bubbles and pores are from trapped gasses which expanded in the molten material as it neared the surface. They're usually found in extrusive igneous rocks, those that have solidified in the air or on the surface.
What are vesicles in an igneous rock?
Vesicles are rounded spaces that appear in igneous rocks from the solidification of the magma around gas bubbles. Pumice, scoria, and vesicular basalt are igneous rocks that contain vesicles.
What are the charicteristics of igneous rocks?
Igneous rocks are nearly always composed of silicate minerals and have an interlocking crystalline structure. The size of the crystals depends on how quickly the rock has cooled. Igneous rocks that cool near or on the surface may also contain gas bubbles.

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.
When molten rocks cools what rocks form?
igneous rocks
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
Are igneous rocks made up of igneous rocks?
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.
What do you call rocks that have been formed from the hot molten material within the earth's crust that has cooled and hardened?
Igneous rocks are formed by the solidification of molten materials.
Where are the two types of igneous rocks made?
Extrusive igneous rocks , Intrusive igneous rocks
