How are air temperature, density, and the movement of air related?

Explain the role of density in the movement of deep currents.
Cold, high salinity deep current water is less dense than warm, low salinity surface current water. As warm water sinks, cold water will move in to take its place, creating a circular movement called a convection current.

Why would a location on the ocean (coastline) have cooler temperatures than a location that is land-locked (no ocean access), even though both locations are at the same latitude? Choose TWO.
The coastline city will have consistently milder temperatures (mild summers and winters) due to the land and sea breezes and currents.
