Abundant fossil evidence did not appear in the geologic record until what geologic era?
Abundant and diverse fossils first appeared in the Cambrian era, although there is fossil evidence throughout much of the Precambrian.
What percent of geologic time is represented by abundant fossil evidence?
The planet Earth is about 4,600 million years old. Fossil evidence becomes abundant in the geological record in the Cambrian Era, which was about 550 million years ago (when hard shelled animals appeared) Therefore (550/4600)*100 = roughly 12% of Geological time contains abundant fossil evidence. However, please note that (non abundant) fossil evidence goes back about 3600 million years, (3600/4600)*100 = roughly 73% of Geologic time.
What three things help scientist estimate geologic time?
The 3 main ideas are, 1. The rock record provides evidence of geologic events and forms of the past. 2. Processes observed on Earth in the present also acted in the past. and 3. Earth is very old and has changed over geologic time.
What is an example of geologic evidence?
This question is simply too general, but i'll give you the definition and an example of the geological evidence of Pangaea.Definition: evidence that geologically prove the existant of such theory inrelation to being of the past (on most occaisions)A geological example of evidence of the existant of Pangaea is how there are coal mines in Antarctica. Coal mines only form near the equator, therefore proving that continental shift was involved and that there was once a "Pangaea".
What is the largest subdivision of geologic time?
The longest in geological time is an Eon eg. Archeozoic Eon . Edit: there is also the supereon, which is usually composed of 2-3 eons.
About 88 percent of geologic time is represented by the time span called what?
88 percent of geologic time is represented by the Precambrian time span.
What would be the best evidence to support a theory that rock layers from different areas are the same age?
geologic colums
Abundant fossil evidence did not appear in the geologic record until about?
Geologic records evidence of abundant fossil is 540 Million Years ago during the Paleozoic Era.
What evidence indicates that oceans formed early in Earth's geologic history?
Radioactive studies and lava flows offer evidence that there has been abundant water throughout Earth's geologic history.
Which recent geologic processes commonly occur in the Coastal Plain region of Virginia?
The processes that occur in the coastal plain region of Virginia refers to geologic processes. The answer is erosion and deposition.

What is the main evidence that supports the geologic time scale?
Measured rates of erosion.

Does catastrophe have weather or geologic or humans cause?
geologic for sure. it is possible that weather may play a role, yet i have not noticed any evidence of human causes for a catastrophe.
