Absorbs and releases heat as part of the water cycle
Compromise of over 60% of living organisms (fauna and humans)

Oceans help to regulate surface temperatures
Water absorbs 20% of insolation (incoming solar radiation) and releases water vapour that absorbs and releases long-wave radiation as part of the natural greenhouse effect
