Why does intrusive igneous rock NOT have air pockets?
the rock cools too slowly for the air pockets to form.
The amount of pressure underneath the surface pops the air bubbles before they can even form.
the rock cools too quickly for the air pockets to form.
The amount of pressure on the surface pops the air bubbles before they can even form.
