What is salinity?

Back

Salinity is the measure of the amount of dissolved salts in water, which affects the density of ocean water.

Front

How does salinity affect ocean currents?

Back

Salinity affects ocean currents by influencing the density of the water, which in turn affects how water moves.

What is the role of the moon in tides?

Back

The moon's gravitational pull creates bulges in the Earth's oceans, leading to high and low tides.
