What information does the geologic time scale have?
Information on time periods in earth's history and the events that happened in those time periods, all based on the study of fossils and rock layers.
Do igneous rocks cool quickly underground?
Intrusive igneous rock is formed underground from slow cooling of magma. The resultant rock stays hot for long periods of time.
Are epochs part of periods?
Periods are subdivided into periods of time know as epochs.
How the characteristics of an index fossil are useful to geologists?
It gives information to scientists about the past. It also provides a reference of time throught rock layers. It can identify and define geological periods of time.
What types of dating estimates the age of a rock or fossil?
The rough estimating of the age of a fossil or rock containing fossils is called relative dating, and is based on the position of the rock or fossil in undisturbed sedimentary strata which contains what are called 'index fossils', fossils that only appear in specific geologic time periods.

Intrusive igneous rock is formed underground from slow cooling of magma. The resultant rock stays hot for long periods of time.
What do the size shape and position of the grains that make up a rock determine?
If the grains of the rock are larger, then it either is an intrusive igneous rock,( a rock formed from molten rock that cooled slowly over long periods of time underground) or a sedimentary rock that was formed from large sediments.

Does it take millions of years to form a metamorphic rock?
Most metamorphic rock processes involve very long periods of time. The exception would be metamorphic rocks formed by meteorite impacts.
