Scientists date igneous rocks to indirectly date nearby sedimentary rocks Why doesn't radiometric dating typically work on sedimentary rocks?
Sedimentary rocks contain bits of sediment, each much older than the rocks they form
An element used to date rocks?
Carbon
Why are no rocks found that date from the first 800 million years of earths existence?
Earth was too hot to have solid rocks at that time.
How do you carbon date rocks 10 million years old?
You cannot. Carbon dating is not useful for dating things more than about 50,000 years old. You would have to use a different radioisotope to date something 10 million years old. Potassium-Argon dating would work for some rocks.
Why do the earliest rock samples date from 800 million years after Earth formed?
IT took the earth this long to cool enough to form rocks

Why cant we use carbon-14 to date the rocks?
Carbon 14 is absorbed by living organisms. When they die, they stop absorbing carbon 14 and the isotope then decays. Form the time of death of the organism, the quantity of C14, as a proportion of the total carbon in the organism declines and, measuring that decrease allows the age (or time of death) of the organism to be determined.

How do scientist date seafloor rocks?
Scientists date sea-floor rocks by looking at patterns in the rocks, including magnetic patterns, and by looking at the geomagnetic reversal time scale.
