The convection cell is basically a self-contained in which there is a motion, where the hotter fluid is moving upward because of the lesser density, while the cooler fluid is moving downward because it is denser. This leads to constant circular movement of the magma in the mantle layer, and the one that moves upward is constantly creating big pressure on the crust above it, penetrating through the cracks in it or melting it and intruding. As the magma pushes upward, it manages to get through the thinner and cracked crust between the plates that move away from each other at the divergent boundary. The magma reaches the ocean floor and quickly cools off, creating new crust, and that continues constantly, with more and more magma coming out and more and more new crust pilling up, eventually creating an underwater mountain range of volcanic origin known as mid-ocean ridge.

The Mediterranean region is not a place where the dairy farming is popular at all, and that is mainly due to the climate in the region which is not really suitable for this type of farming.
Most of the dairy farming is located in the central part of the European continent, where there's mountain ranges and higher elevations, where there's no droughts or extremely high temperatures during the summer, and the grass is green for most of the year.
Answer:
Option (2)
Explanation:
The earth is comprised of numerous species, and this diversification of species gradually increases from the polar region to the tropical region of earth. The tropical and equatorial region is comprised of different species as this region receives the maximum amount of energy, nutrients, sunlight and rainfall.
Some of the biologists often believe that the species diversity increases with the latitude. The higher latitudinal region are mostly covered with ice and glaciers. But without the occurrence of ice age in the past, there is still lesser but sufficient amount of energy that is available in the higher latitudinal region that can support different types of biome, comprising a significant number and variety of species.
Thus, the correct answer is option (2).
