Density Differences in Ocean Water

Multiple Choice

Which action can cause an increase in density that results in a deep ocean current?

• The sun heats the water's surface

• A warm wind blows across cold water

• An iceberg melts, adding fresh water to ocean water

• Warm water loses energy to its surroundings and cools

Engineer It

Assume that a water heater design requires the hottest water possible to be sent to hot water faucets in a building. Where would be the best place for the hot water outlet pipe to be attached to the tank: the top, the middle, or the bottom of the tank? Explain your answer. Let's talk about it! This is practical in life!
