How can a calendar year help us to understand the magnitude of geologic time

Marina86 [1]

Answer:

The civil year allows us to have an idea of how long our planet has existed.

Explanation:

Calendar year is the 12-month period that corresponds to 365 days of the year, counting from 1 January to 31 December. Geological time, in turn, refers to the didactic organization of the evolution of planet Earth and the forms of life that inhabit or inhabited it. It is an instrument used by Earth's geologists and scientists to analyze and chronologically categorize (through the concept of a civil year) the natural evolution of the world in which we live, in order to better understand its past.

The civil year allows geological time to expose the number of years and days that planet Earth (and its forms of life) are in existence.
