Why are surface currents at the surface of the ocean?

• colder temperature
• colder temperature & more salinty
• warmer temperature & less salinty
• less salinty

In addition to salinity, what factor affects the density of seawater?

• depth
• latitude
• temperature
• salt content

Which process increases the salinity of water?

• runoff from land
• formation of sea ice
• precipitation
• melting of sea ice
