The open ocean is more productive in the polar zones than in the equator due to less disturbance to the organisms.
<h3>Why is the open ocean more productive in the polar zones than in the equator?</h3>
In the open seas, heavy winds and deep waters lead to a high turnover in the water column that prevents photosynthetic microorganisms from converting sunlight into energy while on the other hand, there is less disturbance on the polar zones which leads to higher productivity.
So we can conclude that the open ocean is more productive in the polar zones than in the equator due to less disturbance to the organisms.

<u>Advantages of airborne gravity gradiometry:</u>
1) consistent regional coverage
2) It is used when the data is large and it is fast
3) It can be used in varied topography
4) This provides multiple information about a constraint to solve it.
<u>Applications of airborne gravity gradiometry:</u>
Ground gravity survey provide detailed characterization and a higher resolution of a survey area and is comparatively cheap and non destructive. Airborne gravity gradiometry can be used in geothermal exploration, field procedures on an aircraft, environmental mitigation measures on an aircraft.
The Crust and Lithosphere (which are almost synonymous) are not typically divided into two distinctive layers, so we can reject them.
The correct answer is is the core: (b). The inner core is solid and it's made of iron and nickel. The outer layer is liquid and this is the reason for the differentiation of the two parts.
