Time to reflect:

1. Describe the overall changes in life on Earth from Precambrian time to the present.

2. Describe some ways in which the Earth was different from today at the time the Dinosaurs lived.

3. Explain why fossil fuels (coal, oil, and natural gas) are considered to be non-renewable resources.

4. Choose your favorite Geologic Time Period and describe it in detail.

5. Why do you think there is very little information about the Precambrian Period?
