Answer and Explanation:
In case, the major ocean currents stops or slows down, the heat distribution on the Earth will be affected in the following ways:
- There would be quite significant climatic changes.
- It affects one of the major phenomena in the ocean , the thermohaline circulation of the ocean which is responsible for the supply of heat to the polar areas.
- Heat distribution is affected in such a way that keeps the warm water of the equatorial region remains in the same region and can not delivered to the polar areas.
- This phenomena results in more heat in the equatorial region and colder polar areas.
Answer: B. Buoyancy
Explanation: The asthenosphere exerts a buoyant force that pushes up against the lithosphere, and this force resists gravity. The theory of isostasy refers to an equilibrium in buoyancy between the lithosphere and the asthenosphere.
Agriculture availibilty is profound in these areas as fields for agriculture is great for farmers. Spices and vegetables can be grown very well.
