Radiometric dating pretest
Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. As we age, our hair turns gray, our skin wrinkles and our gait slows.However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.They release radiation until they eventually become stable isotopes of lead.
These differing rates of decay help make uranium-lead dating one of the most reliable methods of radiometric dating because they provide two different decay clocks.
So, we rely on radiometric dating to calculate their ages.
Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.
The selection of Earth Science quizzes is also slim, with only 7 at present.
I added the quizzes below to the shared Socrative quiz bank, but also wanted to create a post to share the quizzes that I have been using in my classroom.
