Why does pumice have holes and pockets? |
|
Answer» ong>Answer: The pore spaces (known as vesicles) in PUMICE are a clue to how it forms. The vesicles are actually gas bubbles that were TRAPPED in the ROCK during the rapid cooling of a gas-rich frothy magma. ... As the magma breaks through Earth's surface, the sudden pressure drop CAUSES the gas to come out of solution. |
