Question

Identify and describe two ways the water cycle affects the salt levels in the ocean

Answer 1

Water cycle affects ocean salinity on different levels.

For example, evaporation of ocean water increases the salinity of the ocean, while precipitation and melting of ice decrease it, achieving the balance. Temperature, salinity and water cycle are tightly connected. As global temperatures rises, evaporation increases, and so the salinity. Salty ocean has a tendency to sink. On the other hand warmer ocean rises to the surface and this has influence on ocean currents which then impact the weather.
