[]

Geological Time Playlist

10 points I learned. 1. The central of our planet is as hot as the sun. 2. Precambrian. This is the longest era of four. 3. Precambrian accours 400 billions years ago. This is when bacteria start to evolve. 4. Paleozoic= This is the second longest era of four. 5. Paleozoic occurs 300 years ago. This is when little insect start living on land 6. Meszonic is the third longest of four 7. Meszonic occurs 100 years ago. This is when dinosaur and flowers grow and live. Also this is when the asteroid hit the earth and dinorsaur got extinct. 8.Cenozoic= the shortest of four era. It occurs 65 millions years ago. 9. Plate tectonics are the greatest scientific theory in 20th century 10. There are four era: Precambrian, paleozoic, meszonic and cenozoic

3 Questions: How are the moon formed? why are all the dinosaurs dies when asteriod hit the earth? how do they figured out there are 4 era?
