Early scientific attempts st determining Earth's age gave a number that was around 4.6 billion years old.
<h3>Radiometric dating methods</h3>
The age of rocks can be most determined by radiometric dating.
This process of radiometric dating makes use of two different isotopes of a sample.
It is known that Radioactive isotopes break down within a known amount of time and this enables geologists to determine the age of a sample with the aid of equipment like thermal ionization mass spectrometer.

It is least likely that Japan will be experiencing population growth.
Explanation:
Japan is a country that has a very large population for a country of its size, over 120 million people. Japan though, faces huge demographic problems, which will be more and more serious as the years pass by. The problems now are not that the population is very large, but that the population is aging and will start to experience sharp decrease in the coming decades.
The total fertility rate (TFR) of the country is only 1.27, which is far from enough for simple replacement of the population, as for that a TFR of 2 is needed. Less and less children are born, which in turn provides smaller and smaller population for reproduction with each generation. On the other hand, Japan is a country that has one of the highest life expectancy in the world, and the old population is constantly on the rise.
Such situation brings in lot of economic problems, as very soon the number of old people will equal the number of people of working age, and that is almost impossible to be managed. The Japanese governments have been trying to persuade the young people to form a family and have more children, but the reality is the opposite, as more and more young people decide to be solitary, not form a family, and if they do, they tend to have one child, or maybe two.

i dont because you dont shoe the "Figure 3" sorry
Answer:
The correct answer is A. The prevailing climatic type in the southeastern part of the USA, Western Europe, Southern Brazil and northen Argentina is the mid-latitude or humid temperate.
Explanation:
The temperate climate characterizes regions whose temperature varies regularly throughout the year, with the average above 10 ° C in the warmer months and between -3 ° and 18 ° C in the cold months. They have four well-defined seasons: a relatively warm summer, a fall with gradually lower temperatures as the days go by, a cold winter, and a spring, with temperatures gradually increasing with the passing of days. Humidity depends on the location and geographic conditions of a given region.
