similar to today's climate
fossil is found in the La Brea tar pits indicate a California climate that was
fossils allow scientists to have an idea of a time scale that traits evolve
how can fossils BEST help paleontologist and biologists classify organisms
half-life
in the process of radioactive dating, the fixed period of radioactive decay used to determine the age is called the
they were once underwater
jacob was reading a book about fossils. He read that fish fossils are sometimes found at the top of high mountains. What can Jacob infer about the mountains
decreases
radioactive carbon dating works because the amount of carbon 14 is constant while the organism dies the amount of carbon 14
it was once underwater
spring break had arrived and carol's family went camping along the river seen. During their stay, the family dug for fossils. Carol's father found pieces of elk skull and the bones of some other unidentified animals. Carol found an insect encased in amber and her little brother found two or three shark's teeth. Based on the family's fossil evidence, what can we assume about the past history of the camp site?
relative dating gives age compared to other nearly objects while absolute dating always gives a numerical age
the crucial difference between relative dating and absolute dating is that

Scientists believe that during the Late Cretaceous period, many small seas dried up and new mountains began to rise. Which would most likely cause them to believe the temperature decreased during this time?
fossil a is older than fossil b
Fossil A is found in a layer of rock that is lower than the layer that Fossil B is found in. Based on this information, which statement is correct?

The fossil image is of a trilobite. Trilobites lived in the ancient seas and the fossil was found in the sea floor. Compare the fossil to the four modern-day animals also pictured. Based on physical evidence, the trilobite is probably a direct ancestor of what animal?
