What is the range of pressure in earth’s interior
where rock with a density range of 9.9 to
12.2 g/cm3 is found?
(1) 0.2 to 1.4 million atmospheres
(2) 0.8 to 2.3 million atmospheres
(3) 1.4 to 3.1 million atmospheres
(4) 2.3 to 3.5 million atmospheres

The range of pressure in Earth’s interior where rock with a density range of 9.9 to 12.2 g/cm3 is found to be 0.8 to 2.3 million atmospheres. The answer is number 2. The rest of the choices do not answer the question above.

d. stage 4

explanation:

the existence of some kind of demographic transition is widely accepted in the social sciences because of the well-established historical correlation linking dropping fertility to social and economic development.[1] scholars debate whether industrialization and higher incomes lead to lower population, or whether lower populations lead to industrialization and higher incomes. scholars also debate to what extent various proposed and sometimes inter-related factors such as higher per capita income,lower mortality, old-age security, and rise of demand for human capital are involved.[2]
