What is a volcanic rock with many air holes?
Pumice
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.
