The temperature profile (vertical gradient of temperature) of the oceans is most similar to that of which layer of the atmosphere?
a. troposphere
b. stratosphere
c. mesosphere
d. marine boundary layer

The correct option is: A. Troposphere

Explanation:

The temperature gradient is negative for the ocean. Thus, the temperature of the ocean gradually decreases from the surface up to a certain depth, this region is called thermocline, and then becomes constant.

Similarly, in the troposphere, the lowest layer of the atmosphere, the temperature gradient is negative. Thus, the temperature gradually decreases with height till the tropopause and then becomes constant on reaching the stratosphere.

Therefore, the temperature profile or the vertical gradient of temperature of the oceans is similar to that of the troposphere layer of the atmosphere.

developed and developing countriescountries are divided into two major categories by the united nations, which are developed countries and developing countries. the classification of countries is based on the economic status such as gdp, gnp, per capita income, industrialization, the standard of living, etc. developed countries refers to the soverign state, whose economy has highly progressed and possesses great technological infrastructure, as compared to other nations.
