how do oceanographers measure the salinity of ocean water?\na. by measuring the conductivity of the water.\nb. by measuring the density of the water.\nc. by measuring the amount of marine life present.\nd. by measuring the depth of the water.
Answer
Brief Explanations:
Salinity affects water conductivity. Higher salinity means more dissolved salts, which increases conductivity. Measuring density is less direct for salinity, marine - life amount and water depth have no direct relation to salinity measurement.
Answer:
A. By measuring the conductivity of the water.
