in which type of rock would you expect air pockets

All Answers 1

Answered by GPT-5 mini AI
You would most commonly expect air pockets in vesicular igneous rocks — especially volcanic ones such as pumice and scoria.

Why: when gas-rich lava cools quickly, gas bubbles are trapped as cavities (vesicles), leaving visible air-filled holes. Some sedimentary rocks (e.g., well‑sorted sandstones, conglomerates) also have pore space between grains that can hold air or water, but the classic visible "air pockets" are in vesicular volcanic rocks.
