Hydrology Density Salinity

As Density  increases

• Temperature decreases
• Temperature increases

Temperature  increases

• Density increases
• Density decreases

As salinity  increases

• Density increases
• Density decreases

Ocean depth  increases & Salinity  increases then

• Temperature decreases because cold water is more dense and sinks
• Temperature increases because cold water is more dense and sinks

When an object or substance is cooler, its particles move slower and are closer together True Or False

• True
• False

When an object or substance is warmer, its particles move faster and get further apart (Tip for remembering: they are warmer and want to get cooler by moving away from one another)  True or False

• True
• False

True or False Salinity increases as ocean depth increases.

• True
• False

At which latitudes are the highest surface salinities located? See graph the Atlantic or the Pacific

• About 20o N and S latitude
• About 30o N and S latitude

Which ocean, the Atlantic or the Pacific, has higher average surface salinities?

• Pacific
• Atlantic

Briefly describe the overall relationship between temperature and density.

• Lower temperature water has higher density, warmer water has lower density
• Lower temperature water has lower density, warmer water has higher density
