March 2012 By award winning Mr. Huppert. 1. What is a fossil? A fossil is the preserved remains or traces of living things Provides evidence of how life.
1 T or F - Metamorphic rocks are formed deep in the crust.
Earths Past. Fossils are traces or remnants of past life. Many fossils are found in rock. Rocks, fossils, and other natural evidence provide information.
How do we determine geologic age? 1.Uniformitarianism = the processes that shape Earth have not changed.
Absolute Age Finding a rocks birthday. Absolute Age? Give an example of an absolute age of a rock layer… That rock layer is 200 million years old. Remember,
Relative Time. Relative Dating Relative dating – events are placed in a sequence, but actual occurance dates are unknown. Who is older, Mr. Kopp or Justin.

Geological Time - really, really, really long! Motion pictures are generally projected at 32 frames per second. Therefore, each frame (image) is on the.
Fossils are usually formed when an organism is covered by sediments that then harden into sandstone, slate, mudstone or flint. Most organisms do not fossilize.
