This was for my earth science class pls help?!?!
A student states that the divisions of geologic time are defined by specific amounts of time, so each eon represents that same amount of time, each era represents the same amount of time ,etc. What is wrong with this statement?
A. The divisions of geologic time are separated by significant events in
Earth's history, rather than set periods of time.
B. Eons vary in length depending on the events that separate them;
however, they are divided into smaller divisions of time that each
represent the same length of time.
C. Each eon represents the same amount of time; however, they are
separated into smaller divisions of time that vary in length depending
on the events that separate them.
D. Nothing, this statement is correct.
