How did geologists determine the division of the geologic time scale?
fossils contained within the rock. got answers from Earth Science book while doing my HW
How are the subdivisions of geologic time relate to one another?
they all connect
How paleontologists use trilobites fossils as index fossils for various geologic time 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 one million years sufficiently long to be considered a period of geologic time?
Yes, it is.
What 3 things usually happen to signal a change from one geologic time interval to another?
These 3 things usually happen to signal a change from one geologic time interval to another...rocks changeclimate changesdisappearances or appearances of life
Which one od the following time references best fits the concepts of geologic time?

What is clock of eras?
The Clock of eras is a graphic aid to help us visualize geologic time. It uses the analogy of a circular clock to represent the development of our planet in geologic time. One can see at a glance the relative time lengths of each major geologic era. The Clock represents geologic time on the Earth since its birth to the present, from the initial events that brought about the formation up to now. Each hour represents approximately 375 million years
What the geologic column?
It is an imaginary column where are the ages of rocks sit on top of one another in their proper age sequence, oldest at the base and youngest at the top. An ideal sequence of rock layers that contains all the known fossils and rocks whith each sequence is given its name.

Was a rattlesnake one of the first reptiles?
No, rattlesnakes are a fairly recent family of reptiles to develop, at least when one looks at geologic time.
What ways can you apply your learning in density column?
To build density column, slowly pour liquids into the container, one at a time.
