Answer:
Decline
Explanation:
From the studies that have been done it is expected that the global birth rate will decline after 40 years. There are many reasons for this expectation, some of which are the development of the less developed countries, the people from the villages to move to the cities, more and more people to be out of the poor category, and focusing on careers as the countries develop. Some nations are still expected to have relatively high birthrates, but the majority of the countries will have significant drops in the birth rates, thus the global population will gradually start to slow down its growth, and further in the future stagnate, and probably starting to lower down gradually.
The correct answer is C. It is used to determine the absolute dates in years for different periods.
Explanation
The geological timescale is a tool that has been developed over the years by geologists to establish a frame of reference in which important events in the history of the Earth and life are represented in chronological order. This scale is organized from divisions and subdivisions, from the relative age of the rocks according to their relative age and the absolute time elapsed since the formation of the Earth to the present. Through this scale it has been possible to establish historical periods such as when dinosaurs lived. So the correct answer is C.
