caption_attribution_description: Pumice is a textural term for a volcanic rock that is a solidified frothy lava typically created when super-heated
context_page_description: A pumice raft is a floating raft of pumice created by some eruptions of submarine volcanoes or coastal subaerial volcanoes.
  Biologists suggest that animals and plants have migrated from island to island on pumice rafts.
  Pumice rafts have unique characteristics such as the highest surface-area-to-volume ratio known for any rock type, long term flotation and beaching in the tidal zone, exposure to a variety of conditions, including dehydration, and finally a surface/subterranean remarkable ability to absorb many potentially advantageous elements/compounds. For at least these reasons, astrobiologists have hypothetically proposed pumice rafts as an ideal substrate for the origin of life.
