What property of ice helps promote life?
  1. Due to the low freezing temperature of ice, organisms can more quickly cool down when in close proximity, reducing the chances of overheating in arctic climates.
  2. The unusually dense formation of water molecules in ice allow for water to condense to a much smaller size, giving the planet more land mass to accommodate land-dwelling organisms.
  3. Because ice is less dense than water, aquatic ecosystems do not freeze completely during cold seasons.
  4. Because ice is less dense than water, it can hold more air, oxygenating aquatic ecosystems during the winter.
