A fertility rate of 1 means that the population is aging and decreasing.
Explanation:
The fertility rate is a demographic measure through which the demographers find out what is the number of children born at a particular age group of women, per 1,000. Around the world, the fertility rates differ a lot from place to place, and while some are very high, others are modest, while some are in very bad situation. To put it simple, the higher the fertility rate, the younger the population and the more it grows, the lower the fertility rate, the older the population and it decreases.
If a country has a fertility rate of 1, that means two basic things:
- the population is rapidly aging
- the population is decreasing
A situation like this causes lot of problems, both economic and social ones. The nation itself is also dying out, so without any drastic changes, in several generations a country may become almost empty of its inhabitants. The country that is the closest to such a scenario is Japan.

Glaciation is the process whereby snow has been converted to ice by the force of gravity and pressure.
Answer: Option A.
Explanation:
Glaciation is a process or an activity where a particular area, or land is covered by the glaciers or simply say it is covered by large bodies of ice.
When a snow remains intact in a same area for years, that’s when glaciers are formed. During the process of formation, the snow melts into ice due to the force of gravity and pressure. Every year, as the new layers of snow are formed, it crushes the previous layers of snow. During the process, grains are also formed which causes the snow to increase its density.
This process usually takes many years, and in some additional cases the years even exceeds to hundreds.
Definitely because such a large number of people settled there and built their homes there.
