Seawater is typically denser than freshwater due to seawaters-

• greater depth
• smaller mass
• higher salinity
• lower freezing point

Continental shorelines generally have a milder climate than locations inland at the same latitude due to-

• ocean water acting as a conductor of heat
• land is a greater storage of heat
• ocean water stores and releases heat more slowly than land
• land masses release hear slower than land
