How organisms change over a period of time. What type of rocks contain fossils? How do most fossils form?
Organism dies and is buried by sediment that hardens into compare relative and radiometric dating using the table below. What is raiometric process where tsble replace all or most of an organisms body parts? What are the two most common types of fossils? Takes the same shape of the plant or animal. The space is sometimes filled with mud. The mud hardens and turns into rock. These are not hollow. Looks like the shape of the living thing clmpare into a rock.
The inside of the sedimentary rock is a hollow space that takes the shape of the once living thing. Fossil that records behaviors or activities of uskng organism. Fossil where the delicate parts of the organism are preserved. What substances will preserve original remains? Fossils that have not been permineralized, and are not casts, molds, or trace fossils.
Preserved fossils or original remains. What is radioactive decay? Unstable nuclei break apart and release energy. What is a half-life? The amount of time is takes for one-half of the parent substance to decay into daughter product. What is radiometric dating? What kinds of rocks can we perform radiometric dating on? What is radiocarbon dating?
Using compare relative and radiometric dating using the table below decay of Carbon parent eelative get the absolute age organic objects ie. What is an isotope? Same element with different numbers of neutrons. What is the difference between relative age and absolute age? Relative age is saying a rock layer is older than the one above it yable younger than the one Absolute age is placing an approximate date on the rock such as 4.
Can scientists use radiometric dating to determine the absolute age relatuve sedimentary rocks? We must relate them to other layers surrounding the sedimentary layer. What is the Law of Original Horizontality? Sedimentary layers tend to be laid down in flat layers. What is the Law of Crosscutting Relationships? If a geologic feature cuts across another feature or layer, then that other feature is older and was there first.
