Physical oceanography may be subdivided into _____________________ and dynamic physical oceanography.

The layer of rapidly changing temperature with depth is called a ________________.

The layer of rapidly changing density with depth is called a ________________.

The layer of rapidly changing salinity with depth is called a.

is the density a parcel of water would have if it were raised adiabatically to the surface without change in salinity.

________________________ is defined as the temperature of a parcel of water at the sea surface after it has been raised adiabatically from some depth in the ocean.

In oceanography, a ___________________________is a boundary between two distinct water masses with different temperatures, salinities, or densities.
