Why is it necessary to determine the age of fossils ?” Geological Time Scale is the table showing the sequence and duration of eras and their periods and epochs with their dominant forms of life since the beginning of life on the earth. It proves gradual complexity of life and even extinction of a number of species.
What could be the reason why the geologic time scale was divided into 4 time intervals?
Geologists have divided the history of the Earth into a series of time intervals. These time intervals are not equal to the length of the hour in a day. Instead the length of time intervals is variable. The reason for this is that the geological time is divided by important events in World history.
What does the geologic time scale indicate about the change in life forms over time?
What does the time scale represent? The geologic time scale divides up the history of the earth based on life-forms that have existed during specific times since the creation of the planet. These divisions are called geochronologic units (geo: rock chronology: time).
