1. Describe how population growth is affected by (a) decreasing fertility, (b) decreasing mortality, and (c) rising life expectancy. (6 points)

Explanation: The decreasing fertility of a population will slow the steady increase of children. An example would be Japan where the population is decreasing. Because of this, the mortality would drop over time as less people are expected to die due to a reduced population. Finally the life expectancy would also increase because of an improved diet and healthcare system. An example would be India where the life expectancy increased by over 20 years since 1980.

I think decreasing mortality.

Explanation:

Because death rate is decreasing then birth rate is increasing.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.

answer; the above statement is (false);
