An area of the ocean where rapid change in ocean density occurs with a change in depth is the
Halocline
Which property of water causes coastal communities to have only moderate differences in daily highs and lows when compared to inland communities
High heat capacity
Water can pile up a short distance above a container's rim due to
High surface tension
In comparison to most other liquids, the heat capacity of liquid water is
Higher than other liquids
Sediments produced because of chemical reactions in seawater are called
