• Commercial boating activities.
• The temperature and salinity of ocean water

Ocean water is more dense than fresh water at the same temperature due to differences in:  

• Wind patterns
•  Lifeforms
• Currents
• Salinity

Deep Ocean currents are a result of

• Global Wind Patterns
• Earth's Rotation
• Density
• All of the above

• sea and land
• surface and deep
• warm and cold
