What are some of the processes that change the size, shape or chemical composition of the rocks we see around us?
Are rocks always found exactly where they are formed? Why or why not?
What are some of the processes that move rocks, and how far do you think they can be moved? What are some of the factors influencing how far a rock might be moved?
How are large sements of land, like continents, moved?
Think about the concept of exotic as something that comes from a different place than we find it today. Name some plants or animals that are exotic to where we find them today.
Think of fossils. Have you ever found a fossil? What was it, and where was it found? How do you think it got there?
In what sort of environments would you expect to find fossils?
What sort organisms, or parts of organisms, have the best chance of being fossilized?
What does stdying fossils reveal about the past?
The principle of uniformitarianism is important to the study of geology. This is the principle that the same geologic processes that occur today have not changed [have remained the same] in the course of time; such that we can study present day geologic processes in order to better understand ancient geologic processes. In common language this translates into "the present is the key to the past." Think of how geologists would use this principle to draw conclusions about ancient rocks.

What are some of the major concepts introduced in the program?
How does plate techtonics shape the landscape around us?
What major geologic processes create the Blue Mountains Island Arc? How?
What process moved it a long distance to merge with the North American continent?
What were some of the scientific clues that helped scientists understand the history of this exotic terrane?
What are some of the challenges particular to studying exotic terranes?
How does the principle of uniformatarianism apply to scientists' understanding of the Blue Mountains Island Arc?
In what ways are geologic forces still changing this terrane?
What do geologists mean when they say our planet is dynamic?
