granite is extrusive rock
These are all formed by volcanic activity. Igneous
there are many types of rocks created by lava including: basalt, andesite, rhyolite, obsidian, tuff, pumice, cinder, and scoria.
== == Rhyolite, basalt, pumice, obsidian, andesite, dacite, tuff, welded tuff, scoria.
They cooled too quickly for crystals to form.
Pumice and scoria are volcanic rock. They form form the lava the erupts from the volcano and contains bubbles from gasses. These bubbles cause the cavities you're calling air holes.

None of those. Scoria, Pumice and Granite are igneous rocks. Sandstone is sedimentary.

Basalt and rhyolite are examples of extrusive igneous rocks. Also, pumice, scoria, obsidian, tuff, ignimbrite,....
