Answer:

Option (D)

Explanation:

The new sea floor are formed along the mid-oceanic ridge, in a divergent plate tectonic setting where two plates move in the opposite direction. The convection current that forms in the mantle forces the magma of basaltic composition to rise up and results in the formation of cracks through which the magma erupt at the seafloor. These magma are deposited along this mid-oceanic ridge where the new materials are added and the rocks formed in and around this ridge are the youngest rocks.

Thus, the source of this magma is the mantle.

Hence, the correct answer is option (D).

The population growth or population recovery will be an exponential growth curve. The linear fit on the given data will help model the recovery of the population in future time. The attached image shows the linear fit and its extrapolation till the year 3000. The linear fit gives a good underestimate of the population in the years after 2530. Hence the answer is D. a date in the distant future.
