Which parameter of the hydrosphere does not change?
a. density vs depth at low latitude
b. surface temperatures from low to high latitude
c. temperature vs depth at high latitude
d. temperature vs depth at low latitude

In hydrosphere, the parameter surface temperatures does not change from low latitude to high.  

Option B  

Explanation:

                  Hydrosphere is made with all available water on earth, sea, planets and lakes. Its role is to sustain water various life and maintaining ecosystems. Water is present in high percentage on the earth's.  

                  Comparing surface temperatures and lower temperatures in high latitude areas, lower sea surface temperatures found at high latitudes. In the deeper ocean, the water temperature is similar to the surface temperature, keeping the curve vertically. Hence, there is no rapid changes in the temperature with depth (remains constant).
