Because of the fluctuation.
In most ocean regions, wind-driven circulation, which has been the focus of discussions so far, does not reach below the first kilometer of the oceans. The renewal of the waters below this depth is achieved by currents that are guided by differences in density produced by effects of temperature (thermals) or salinity (halinos). The associated circulation is therefore referred to as the thermohaline circulation. Since these movements are mostly quite slow, it is very unlikely to use direct current meters (current meters); they are usually estimated by the distribution of the physical properties of the water and the application of geostrophy.
The driving force of thermohaline circulation is the formation of water bodies. Water bodies with well-defined salinity and temperature characteristics are created in specific regions by surface processes; they then sink and slowly mix with other bodies of water as they move. The two main processes for the formation of water bodies are deep convection and subduction. Both are linked to the dynamics of the mixing layer on the surface of the ocean; thus, it is necessary to first discuss thermohaline aspects of the surface ocean first.
The answer to this is farming.
Most deaths occur in farming because of the flying debris. Some of the survival occurs in farming too. When there is a tornado the people usually take shelter in root cellar.
Hope this helped :)
Have a great day

A. Gross Domestic Product per capita.
Answer: (A) Face-to-face interview
Explanation:
The face-to-face interview is one of the method of data collection by communicating directly with the other person.
This type of interview basically ensure the quality of the given data and it also helps in increase the total rate of the response.
The main purpose of the face to face interview is to explore the information by directly communicate with the person and also judge their capabilities.
Therefore, Option (A) is correct.
