4.7.2 Temperature, Depth & Pressure & SALINITY (SOL 4.7)

Front

What is salinity?

Back

Salinity is the measure of the amount of salt dissolved in water, particularly in ocean water.

Front

How does water pressure change with depth in the ocean?

Back

As you go deeper into the ocean, the water pressure increases.

Front

What happens to the temperature of ocean water as depth increases?

Back

The temperature of ocean water generally decreases as depth increases.

Front

What is the relationship between depth and the number of living organisms in the ocean?

Back

As depth increases, the number of living organisms typically decreases.

Front

How does salt enter the ocean?

Back

Salt enters the ocean from rain that runs off rocks and land into rivers, as well as from the erosion of rocks.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment, which changes in response to the independent variable.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

What is the effect of temperature on the rate of evaporation?

Back

Warmer temperatures generally increase the rate of evaporation compared to cooler temperatures.

Front

What is the main source of salt in ocean water?

Back

The main source of salt in ocean water is the weathering and erosion of rocks on land.

Front

What is the significance of studying temperature, depth, and pressure in the ocean?

Back

Studying these factors helps us understand ocean ecosystems, marine life, and how they are affected by environmental changes.
