What argument convinced most scientists in the 1800s that Earth was more than 6,000 years old? O The discovery that radioactive isotopes could be used to determine historical dates O Arguing that everyday observable geological processes (like erosion) could explain large geological features if they had occurred for millions of years, rather than large catastrophic events that happened suddenly O The discovery that Earth orbits around the sun, rather than the sun orbiting around Earth O The discovery of fossils

A fossil is found to contain the radioactive parent and daughter isotopes uranium 235U, and lead 207Pb, in the ratio 12.5% to 87.5%. Assuming that no 207Pb was present when the fossil first formed, estimate the age of this sample.Please show some thought process and a therefore statement. Thank you very much, have a great day!
Four billion years ago, the Earth was a thin-crusted inferno. Which probable stage of physical and chemical evolution of life is that?
For this activity, you will be reviewing the geological time scale in the module readingassignment from the Geological Time chapter in the PRI Digital Atlas of Ancient Life –online textbook and the Earth History chapter from the OER Commons Earth ScienceTextbook. Use the images of the geologic time scales in your readings to help you makeyour Geologic Time Scale concept sketch nstructions:Sketch and label a geologic time scale. Include dates of the following events in EarthHistory on your time scale in the appropriate time period (you may have to look these up onthe internet but most are listed in your readings). First appearance of free oxygen in the atmosphere Earliest fossils Oldest animal fossils Great Dying Extinction (worst mass extinction at end of the Permian Period) – alsoexplain possible causes of this extinctionArchaeopteryx sp. appeared First Flowering PlantsTyrannosaurus rex appeared K-T Extinction event (Dinosaurs died out) – also explain possible causes of…
One benefit of the fossil record isa. that hard parts of bodies are more likely to fossilize.b. that fossils can be dated.c. its completeness.d. that fossils congregate in one place.e. All of these are correct.
If you think of geologic time spans as minutes, life’s history might be plotted on a clock such as the one shown below. According to this clock, the most recent epoch started in the last 0.1 second before noon. Where doesthat put you?
What theory of fhe origin of life do you think is most possible?why?
How does finding the same fossils of a land animal on two different continents support the hypothesis of continental drift? A) The land animal fossil is now found in colder parts of the world which means the continents had drifted since the fossils were made. B) The land animal fossil could only have ended up fossilized on both continents if they were once together C) The land animal fossil was unable to swim across oceans so the fact that its fossils were found on distant continents suggested those continents had once been fused together as later moved apart. D) The land animal fossil wasnt found in Asia which wegner thought was only stable continent that hadn’t moved.

In which type of rock are you more likely to find a fossil? a. basalt, a dark, fine-grained volcanic rock b. limestone, composed of calcium carbonate sediments c. slate, a volcanic melted and cooled shale d. granite, which forms by crystallization of molten rock below the surface of the Earth
