4.05 Ocean Water

Front

What is the main reason areas at low latitudes have the warmest ocean water?

Back

Areas at low latitudes receive the most direct sunlight.

Front

What is the most common salt found in ocean water?

Back

Sodium chloride.

Front

How does the temperature of ocean surface water vary with latitude?

Back

Areas at high latitudes have the coldest water.

Front

What three factors are most important in determining the composition of ocean water?

Back

Temperature, salinity, and density.

Front

What happens to temperature and pressure as ocean depth increases?

Back

Temperature decreases and pressure increases.

Front

Define salinity in the context of ocean water.

Back

Salinity is the concentration of salts in water, typically measured in parts per thousand.

Front

What is the relationship between ocean temperature and density?

Back

As temperature decreases, density increases.

Front

Explain how sunlight affects ocean water temperature.

Back

Sunlight warms the surface of the ocean, leading to higher temperatures in areas with more direct sunlight.

Front

What is the significance of ocean currents in temperature distribution?

Back

Ocean currents help distribute heat across the ocean, affecting local temperatures.

Front

How does the salinity of ocean water affect its density?

Back

Higher salinity increases the density of ocean water.
