The Geological Column is a popular timetable used to mark different strata by the use of fossils. Geologists have found that classifying rocks by comparison of fossils in all parts of the world is a very valuable tool. Part of the historical geological record is made using index fossils spanning 570 millions years.
Most geologists believe that all the continents presently situated around the world were once linked forming one super-continent called Pangaea. From the evolutionary perspective those who study Plate Tectonics theorize that this super-continent broke up at the end of the Mesozoic era that evolutionary theory say began 250 million years ago.
Geologists are scientists who deal with the earth’s physical structure and substance, its processes, and its history. My scientific degree is not in geology, but I have read extensively about geology and have observed geological features while traveling throughout North America. We can see the geological features and processes as they exist now, and can speculate about their past history. With modern technology geologists can examine the earth, and can measure the rate at
