If the isochron slope is 0.0077 what is the age in millions of years when first evidence of abundant fossils?
If the isochron slope is 0.0077, the age in millions of years when the first evidence of abundant fossils would be around 129 million years (1/0.0077). This calculation assumes a linear relationship between the isochron slope and time.
How did fossils provide evidence for contental drift?
Because, similar fossils could be found on different continents, in rocks of the same age.
What can rock fossils and original remains show about earths rock?
it can show a rocks age and what it has gone through
What fossils are useful in determining the relative age of rocks?
Index fossils
How do geologists use fossils to determine rocks age what are this fossils called?
Geologists use fossils to determine the age of rocks through a process called biostratigraphy. They identify the specific group of fossils present in the rock layer, known as index fossils, that have a known age range. By comparing the index fossils to a geological time scale, geologists can estimate the age of the rock layer.

What was Elizabeth Proctors age in The Crucible?
By calculating the evidence provided. I have made the conclusion that she is indeed a certain age.
What sentence best describes the information provided by radiometric dating?
Radiometric dating measures the decay of radioactive isotopes in rocks to determine their age.
How do trace fossils differ from index fossils?
Trace fossils are any evidences that an organism existed, including footprints, trails, burrows, chemical marker, and fossilized dung.Index fossils are those that are only found in a specific range of geologic time, and are used to quickly determine the age of a sedimentary rock sample.

How index fossils can be used to determine the age of rocks?
Index fossils are used to date rocks by correlating the fossils found in the rock layers with known ages of those fossils. Index fossils are distinctive, widespread, and lived for a relatively short period of time. By identifying these fossils in a rock layer, scientists can infer the age of the rock based on the age range of the known fossil.
What are index fossils and how are they used to determine the absolute age of sedimentary rock?
Index fossils are fossils of organisms that lived for a relatively short period and had a wide geographic distribution. By identifying these fossils in sedimentary rock layers, scientists can determine the relative age of the rock based on the known age range of the index fossil. Absolute age dating techniques, such as radiometric dating of igneous rocks that bracket the sedimentary layers containing the index fossils, are then used to determine the exact age of the sedimentary rock.
The age of the earths crust can best be determined from the studies of A the salts of the oceans B the type of fossils left behind C erosion from a river D radioactive decay E surface weatherin?
Radioactive decay
What are index fossils and how are they used to determine the absolute age of sedimentary rocks?
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.
