FC: bellas project
1: on the first day of school Bella went to the library at her school to research on a project she was working on for her new science class.she couldn't find any good books for her project.
2: A boy named Jacob asked her if she needed help with her project.She said she was having trouble finding books to research fossils and rocks.He said he could help her he knew almost everything about fossils and rocks.Jacob asked if she wanted to go to the mountains to look for some rocks to research.Jacob is a geologist.If you don't know what a geologist is its a person that studies the solid and liquid matter that constitutes the earth as well as the process and history that shaped it.Geologist usually engage in studying geology.Jacob took Bella and Edward to Alaska.
3: Bella asked allot of questions at her age sense she was only 10 years old.Edward was talking about relative age but Bella did not understand what it meant so Jacob explained to her in a way she could understand. "relative age is younger or older but absolute age determines how old the rock is, determining absolute age by using the rate of erosion is practical only for geological features that formed within the past 10,000 to 20,000 years". Edward said that there is a method of determining the absolute age of an object. "comparing the relative percentages of radioactive (parent) isotope and a stable (daughter) isotope ,they use known decay to find
4: out the absolute age".Bella asked if anyone had seen James. Edward said that he was at the lake studying bounded layers of sand and silt that is deposited each annually in a lake thats why he went to study it.James and Bella found fossils at the lake Bella said "did you know there is three main types of fossils they are imprints,casts ,and mineralization of bones.
5: James introduces Victoria to Bella.Victoria is a paleontologist a person that studies fossils.Fossils are the trace of remains of organism that lived long ago.Most fossils were commonly preserved in a sedimentary rock.Victoria found a fossil of a vampirasourus and a wolfasourus.They are dinosaurs that lived 100,000 years ago.Bella was happy she finally understood the rock cycle.
