In the latter case, quantitative estimates of time are conducted in modern astronomical units—years or Earth’s rotation time around the Sun.Specific geological ages, which can be referred to as absolute times versus relative times, are determined conventionally by radiometric methods.Our attention here is focused on the characterization of geological time that encompasses the evolutionary sequence of the material geological environment, or more accurately, the stratigraphic divisions.We call time geological due to specifics regarding the fixation of geological events over billions of years.Age of the Earth; Earth’s radius; Radioisotope dating; Non-radioisotope dating; Fossil corals Earth’s history from the moment of its birth has been an important subject of geological science.One of the key goals has been to not only determine the conditions surrounding the formation of Earth, but also the whole evolutionary sequence of Earth and periodization of all major geological events.As is known from studies of 400 million year old fossil corals, Earth years were 400 days in duration in distant times because the Earth rotated faster than it does today.

The estimates are derived from isotope data, which are converted into radiological ages.For example, are the data complementary or incongruent?The goal of this work is to find the answer to this question.Relative geological times for events in Earth’s history are presented in relation to times of other geological events.These times are determined based on corresponding positions of ground layers, i.e., lower layers are ancient in unbroken ground layers, whereas the upper ones are younger.
