Answer:
Sediments are used to provide the proxies to understand the environmental changes as, the sediments are formed by the activity of the weathering from the wind, glacier and the water. The different weathering agent and other transportation agent are different types of the mark over the sediments that help in the study of the past environment.

Answer:
The correct answer is C. A large Russian population in the Highlands is not represented in modern day Brazil.
Explanation:
The population of Brazil consists of more than 210 million people. Of this total, 59% is white, predominantly descended from Portuguese, Spanish, Italians and Germans; 30% is black, with origins in the African slaves brought by the Portuguese to the Brazilian territory; and 11% belong to native indigenous groups, which live predominantly in the planalto and the Brazilian Amazon.
In the case of the Russian-Brasilians, it is estimated that some 300,000 descendants of this nationality currently live in the national territory of Brazil, but they do not make up a relevant demographic group in the ethnic analysis of the country.
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.
