Answer:

The Correct Answer is B

Green Revolution

Explanation:

• Third Agricultural Revolution is a collection of investigation technology shift actions happening between the '50s and the new 60s, that developed farming stock universal, especially in the developing society, occurring most especially in the new 60s.
• Green revolution applies to the initiation of High yielding variety (HYV) of grains and extended use of compost and spraying systems.

Final answer:

The Third Agricultural Revolution, occurring in the mid-20th century, is also known as the Green Revolution. It represented a significant shift, utilizing more industrial and technologically advanced agricultural techniques to support the growing global population. This period also resulted in various socio-economic and environmental concerns.

Explanation:

The Third Agricultural Revolution is also referred to as the Green Revolution. This period of time was characterized by considerable advances in agricultural techniques, such as the use of genetically modified organisms (GMOs), fertilizers and pesticides, and it occurred during the mid-20th century. The Green Revolution represented a major shift from traditional agricultural techniques to more industrial and technologically advanced methods. The ultimate goal was to yield larger amounts of food to support the growing global population. Significant aspects of the Green Revolution included the more extensive use of mechanical machinery, the development of high-yield crops, soil and water management, and the application of synthetic fertilizers and pesticides. It is worth noting though that while the Green Revolution positively impacted food production, it also brought about various socio-economic and environmental concerns.

Answer:

The four stages of demographic transition are namely high equilibrium, early population growth, late population growth, and low equilibrium.

Explanation:

• In the process of demographic transition, the first stage that appears is that of high equilibrium.

• In this stage, the "birth rate and the death rate" are equal. After the first stage of high equilibrium, comes the next stage of early population growth.

• In this stage, the population keeps growing due to the "decrease in the death rate". In the third stage of late population growth, the population growth rate stabilizes due to decreased birth rate.

• In the final "stage of demographic transition", i.e. in the stage of low equilibrium, both the death rate and the birth rate reach their lowest.

Answer:

D. Reversal of Earth's magnetic field

Explanation:

The earth's magnetic field changes over time and this causes changes in the direction of magnetization of magnetic elements or minerals in rocks.

Our magnetic field is widely believed to originate from activities within the outer core where molten iron and nickel moves. The flow of these molten elements results in the production of the magnetic signatures on earth surface.

Some elements and minerals within rocks are capable of recording the direction of magnetic fields at a period in time. Before magma cools, such minerals in these rocks aligns their poles to that of the prevailing direction of the earths magnetic field. This is how the magnetic changes at the mid-oceanic ridges are recorded.

Answer:

The process of seafloor spreading is responsible for "creating magnetic changes" along mid-ocean ridges.

Explanation:

• When "seafloor spreading" occurs along the mid-oceanic ridges, it results in a drastic splitting of the oceanic floor over a large area.

• This in return changes the orientation of the predominant magnetic fields and the intensity of their strength in the region.

• The mid-oceanic ridges are majorly constituted of solidified lava which is rich in iron.

• The changes that occur in the local magnetic fields due to seafloor spreading thus create magnetic changes along the mid-oceanic ridges.
