Why didnt the early geologic time scale include the number of years ago that events happened?
The early geologic time scale did not include specific numerical ages for events because it was primarily based on the relative dating of rock layers and the fossils they contained, rather than absolute dating methods. Scientists relied on the principles of stratigraphy and biostratigraphy to establish the sequence of geological events without assigning precise dates. It wasn't until the development of radiometric dating techniques in the early 20th century that geologists could accurately quantify the ages of rocks and events, leading to the modern geologic time scale that includes specific timeframes.
What else can I help you with?
The absolute age of a geologic event in the rock record is?
the number of years that have elapsed between the event and the present day
What is the most destructive geologic hazard?
Earthquakes are considered one of the most destructive geologic hazards. They can result in widespread destruction of buildings and infrastructure, loss of life, and long-term economic impacts. Tsunamis triggered by earthquakes can also cause devastation in coastal areas.
How does the existence of people on Earth compare with the length of geologic time on Earth?
The existence of people on Earth is relatively short compared to the length of geologic time on Earth. Humans have been around for only a tiny fraction of Earth's history, which spans billions of years. Geologic time encompasses vast scales of time, with the history of humanity representing just a minuscule portion of it.
What happened 1.9 years ago?
Since 1.9 years ago is roughly equivalent to 1 year and 10 months, any number of events could have occurred during that time. Without additional context, it is impossible to provide a specific answer.
How do Scientists reconstruct geologic history?
Paleontologists study fossils, archeologists study past human life, climatologists can study past climates, geologists can study various things about Earth's past - the point being that a number of different scientists may study fossils in their disciplines.

How do paleontologist use trilobite as index fossil for various geologic periods?
Trilobites were rapidly evolving and widespread marine organisms that spanned a number of geologic time periods. Certain types of trilobites only appeared in specific segments of geologic time; therefore, when one of these trilobites is found, you can be certain that the rock layer it is found in is of a certain geologic age.
Is their any lotto number combination that has not happened?
Probably, since there are so many possible combinations. Knowing which one hasn't happened, though, is not useful - the outcome of past random events won't have any future on future random events of the same type. For more details, look for "Gambler's fallacy", in Wikipedia.
