Paragraph-how high GDP can affect child mortality​
Jet001 [13]

Answer:

The authors found that, on average, a 1% reduction in the per capita GDP implies a 0.24 to 0.40 increase in infant mortality per 1,000 live births. In a more recent study, O’Hare et al.17 found effects of 0.33 for infant mortality and 0.28 for under-five mortality. These results are higher than those observed in the present study, which found an association of approximately 0.12 for infant mortality and 0.10 for under-five mortality rate for the total sample, and 0.15 and 0.14, respectively, for the subsample of low- and middle-income countries. This difference is probably due to the countries included in the sample, as Baird et al.14 and O’Hare et al.17 include only middle- and low-income countries in their analysis, while the present study included countries from the three income strata, with only 14% of the sample consisting of low-income countries. According to Maruthappu et al.6, the effect of economic crises on the health of children under five in the poorest countries is three-fold higher than the effect on children in high-income countries.

In the mid-twentieth century and corroborated ever since, researchers dredging the seafloor could not find any materials older than 180 million years.

<h3>What do you understand by seafloor ?</h3>

The surface of an ocean or sea: seafloor According to this theory, the Earth's crust is divided into a number of enormous plates that together form the continents and ocean floors and are supported by a warm, plastic "mantle" beneath the surface. Mr. Walter Sullivan

Deposits of common minerals like copper, zinc, nickel, gold, silver, and phosphorus can be found on the seafloor. These deposits are nodules on silt from the abyssal plain that are typically 3 to 10 centimeters (1 to 4 inches) in diameter and appear as crusts on volcanic and other rocks.
