Scientists today study rocks from all eras.
It is impossible to accurately compare the wealth of people who lived in different eras. The value of the dollar varies greatly at different times as do the values of land holdings and slaves . Even with people who live at the same times it often impossible to make a fair assessment of net worth. See the related question for a list of wealthy presidents.
It is difficult to answer this question, because we do not know which two eras you want us to compare: different today as compared to what other era? The lives of children have certainly changed over the decades, so if you give us more information, we can give you a better answer.
We have more new technology to find out what these things are and how they work, so we can diagnose them unlike in earlier eras, where technology and knowledge isn't like it is today.
There are 4 eras, and they are the Hadean, Archean, Proterozoic, and Phanerozoic eras.
Eras are great lengths of time but periods are the small amounts of time in eras.
Eras is already plural. The singular is era.
Eras are divided into periods.
Periods are subdivisions of geological eras.
There were 7 eras in ancient Rome
Geological eras can be divided into periods, epochs and ages.
Willy Eras was born on 1980-09-10.
A little research that forces you to have to read will do a whole lot better than posting college questions looking for the easy way out. Come on man. Open a book.
No, I'm not and neither are you. People are not entitled to their own individual geological eras.
This question needs to be more specific. Life in different eras was different...but perhaps provide specific eras for a better result.
Beethoven lived in the classical and romantic musical eras
They are three main parts of the eras and have distinctions.
Periods, not eras. The Jurassic Period, Cretaceous Period, and Triassic Period.
Most scientists agree that there are 3 eras for every eon.
There are only three recognized eras. The time periods before that are called eons, and aren't divided into eras. The first of the eras was the Paleozoic, which lasted from 570 to 225 million years ago, second was that Mesozoic, the so-called "Age of the Dinosaurs" which lasted from 225 to 65.5 million years ago, and lastly, the Cenozoic, which began 65.5 million years ago and continues today.
Eras are subdivisions of larger units of geologic time called eons.
i believe there is 4 eras
Eras are separated by major events that occurred in these eras. At the end of Mesozoic the dinosaurs were extinct and in the paleozoic there was the Permiam Triassic Extinction
There were several major eras of one party domination in American History. A couple of the eras was the Great Depression and the 1960s.
