Question - How do you know how old rock layers are?
Answer - We use relative dating and absolute dating.
Question - What are the methods you use for absolute dating?
Answer - some of the methods we use include, Carbon-14, Potassium-40, argon-40, uranium-235, and lead-207.
Question - what is absolute dating?
Answer - absolute dating is the age of a rock layer in years.
Question - What is relative dating.
Answer - Relative dating is used to put rock layers into a sequence without determining the actual age.
Question - What do you call undisturbed rock layers that are youngest to oldest?
Answer - We call that the law of superposition.
Question - What type of fossil is most useful for relative dating?
Answer - Typically fossils that are widespread are most useful.
Fossil Picture Diary
This is an amber fossil. An amber fossil is a fossil formed when an organism dies and fossilizes in sticky tree sap.
This is an example of petrification. Petrification is the process in which minerals replace an organism’s tissues.
This is an example of an asphalt/tar pit. An asphalt/tar pit is a way in which organisms have been fossilized by being trapped and preserved in sticky thick pools.
This is an example of a frozen fossil. A frozen fossil is a fossil that has been preserved in ice for a long period of time.
This is an example of a cast. A cast is a type of fossil that forms when sediments fill in the cavity left by a decomposed organism.
This is an example of a mold. A mold is a mark or cavity made in sedimentary rock by a shell or other body parts.
This is an example of a trace fossil. A trace fossil is a fossilized mark that shows activity or movement of an animal.
Geologic Time Travel
Current Events (Corryn)
On September 3, 2016 paleontologists found fossils from more than 150 million years ago. They named them Pterouses. They seem to be flying reptiles. They are the same size of the average size of cats. They are ancestors of birds. Though there dinosaurs, they only were alive during the end of the dinosaur age. Tey became extinct when something wiped out all of the bird dinosaurs. Pterouses are a very successful group of animals, they were the first to master flight. The early ancestors of Pterosaurs were tiny bird but evolved into cat sized reptiles that could fly. Later in the years, there formed another species of Pterouses formed, they were called Azhdarchids, they were so big because th
Current Events (Lily)
“Mosasaurs – an extinct group of aquatic reptiles that thrived during the Late Cretaceous period – possibly were “endotherms,” or warm-blooded creatures, a paper co-written by a University of Alabama professor suggests.”
