Answer:
In the pre-classical age (8000 B.C.E. to 600 B.C.E.) the first states developed in core civilizations. Then, powerful cities imposed their rule on surrounding areas through conquest and the first empires were born. In the classical age (600 B.C.E. to 600 C.E.) empires grew on a massive scale through territorial conquest with large armies. The growing scale of these empires, along with their increased ethnic and cultural diversity, required more sophisticated methods of governance. They served as major hubs of transregional networks of trade, and they diffused culture, religion, technologies and disease. As empires acquired massive wealth, the unequal distribution of this wealth across social classes placed enormous pressure on the political and social order. Eventually, all of the classical civilizations could not deal with the problems created by their own internal or external crises. In most cases, the belief systems spawned in these empires left enduring cultural footprints even as the empires' political structures disintegrated.
Answer:
A. The Birth rate (per 1,000 population) and the birth rate (per 1,000 population)
B. Expected number of children per childbearing woman
C. 50 years
D. The population will decrease
E. Unusually low rate of natural increase and total fertility
Explanation:
A. The two types of data in the table that are used to calculate the rate of natural increase are The Birth rate (per 1,000 population) and the birth rate (per 1,000 population)
B. The total fertility rate is the number of children expected per woman during her childbearing years
C. The doubling time is given by T = 70/(1.4) = 50 years
D. To maintain the current population size, a fertility rate of 2.1% is required, whereby the fertility rate is about 1.8% the population will not be stable or would decrease
E. The population statistic with a total fertility rate below 1.8, a low rate of natural increase, and a low birth rate is not inline with other industrializing economies such as Middle East, with a fertility rate of 3.0.
Answer:
<h3>Questioned what might happen if CFCs rose into higher altitudes and stayed there for a longer period of time.</h3>
Explanation:
- Mario Molina noticed that Chlorofluorocarbons (CFCs) did not breakdown in lower atmospheric conditions unlike other chemicals released into the air. He observed that CHCs rose to higher altitudes where solar radiation were stronger.
- Through this observation, he questioned what might happen if CFCs rose into higher altitudes and stayed there for a longer period of time. This question led to the finding that the chlorine present in CFCs depleted the ozone layer which protects the earth from direct solar radiation.
- It helped in understanding the affects of CFCs to the environment and ozone layer which subsequently led to the ban and limitation on the use of CFCs altogether.
