**What three things did you find the most interesting**
One thing that I found most interesting was how scientists estimated the time when earth was made. The second thing that I found most interesting was how the plate tectonics move and how they effected the continents. The third thing that interested me was how the different rocks told the timeline and where they have been such as the bottom of a ocean. 

**what three things did you find the most boring (you already knew about them etc)**
I think that the stuff about the fossils where pretty boring. I also think that when they where talking about how they figured out how the continents moved.(because I already knew) Another thing I thought was boring was Glaciers moving slow motion.

**What one thing do you want to know more about**
I would like to learn about how scientists view evolution. [|http://en.wikipedia.org/wiki/Fossils]

**then write a three paragraph summary on your wiki page**
Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past. fossils vary in size from microscopic to very large. Various explanations have been put forth throughout history to explain what fossils are and how they came to be where they were found. Ever since recorded history began, and probably before, people have noticed and gathered fossils, including pieces of rock and minerals that have replaced the remains of biologic organisms, or preserved their external form. Fossils tell us things about the past.

With the technology that scientists have come about, scientists can determine around the time that the fossil was decayed. Fossils also tell us what where living on the earth. They also tell us about the conditions that they had to face. Some fossils tell us where the species where located. More scientific views of fossils emerged during the Renaissance. Fossilization is an exceptionally rare occurrence, because species decompose rather quickly after death. In order for an organism to be fossilized, the remains normally need to be covered by sediment as soon as possible. However there are exceptions to this, such as if an organism becomes frozen. There are several different types of fossils and fossilization processes.
