Question

Name the only rock that can float?
A. Basalt
B. Andesite
C. Pumice
D. Obsidian

Answer 1

Answer- pumice. Pumice has hundreds of tiny air bubbles in it. When it was made in a volcano, the volcano's force pushed air into the rock. This makes pumice very light. It usually floats for a while, but then water gets into it and it starts to sink.

Answer 2

c) is the right answer.
