Geological Time Playlist, 10 things I learned:

1. The center of our planet is as hot as the surface of the sun. 2. The core is what fuels volcanos to this very day! 3. While rocks were circling the sun, it collide with other rocks and created slot of heat. Eventually, when the outer later of the planet cooled, the two powerful sources of heat were trapped in a huge, hot core. 4. The earth's hot core has been continuously releasing heat. 5. After 4.5 billion of years, earth's still produce heat. 6.PreCambrian is the longest era out of four. 7. There were so many bacteria that people wouldn't want to live there in those days. 8. Paleozoic is the second longest era out of four. 9. Mesozoic is the third longest era out of four. 10. Cenozoic is the shortest era of all.

great but missed the three questions and statement 45/48
