volcanos by Jordan and Austin

If you are wondering how hard volcanoes can erupt then it can go up to 27,000 atomic bombs going off!

Does volcanic ash fly over 1000 feet? Yes volcanic ash can fly over 1000 feet.

If you ever wondered how volcanoes form? They form from explosions in the ground and rock piling up.
