Radiometric dating means placing events in their proper sequence
Rocks from several localities have been dated at more than 3 billion years 3. The grains composing detrital sedimentary rocks are not the same age as the rock in which they occur b.
PALEONTOLOGY, AND in particular the study of dinosaurs, is an exciting topic to people of all ages.
Extinction of species is common; most of the species that have lived on the earth no longer exist.
*Earth and Space Science: Fossils provide important evidence of how life and environmental conditions have changed.
The module is an integrated unit which addresses the following National Science Education Standards: *Science as Inquiry: Students develop the abilities necessary to do scientific inquiry identify questions, design and conduct scientific investigations, use appropriate tools and technologies to gather, analyze and interpret data, think critically and logically to make the relationships between evidence and explanations, communicate results, and use mathematics in all aspects of scientific inquiry.
Radiometric dating is a complex procedure that requires precise measurement 2.Return to top The study and comparison of exposed rock layers or strata in various parts of the earth led scientists in the early 19th century to propose that the rock layers could be correlated from place to place.Locally, physical characteristics of rocks can be compared and correlated.Although most attention in today's world focuses on dinosaurs and why they became extinct, the world of paleontology includes many other interesting organisms which tell us about Earth's past history.The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.
Search for radiometric dating means placing events in their proper sequence:
Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age.
