2: Hadean Eon When it happened Hadean era began about 4.6 Billion years ago, and it ended 3.8 billion years ago.

4: Hadean Eon's What was happening Hadean era was a violent, Dangerous time. Earth was constantly bombarded by meteorites. Its surface was hot and molden, and the clouds were filled with gas and the air was poisonous. Hadean Eon was close to when the earth formed. So at that time Earth was really hot and there was alot of magma

6: Hadean eon Zircon Zircon is the oldest mineral in the world. It was formed during the Hadean eon. Study of zircon has found that liquid must have existed long ago as 4.4 BILLION years ago, very soon after the formation of the earth; a zircon is a mineral occurring as a prismatic crystal, typically brown but sometimes translucent of gem quality.

8: Hadean Eon Moon Some scientists have theorized that the moon was created in the time of Hadean eon. We do know that the Earths surface was incredibly unstable. The scientists had 2 theories of how the moon formed. One was when two places of the earth have completely seperated form earth and the two pieces of huge rocks formed. The other was when a smaller planet came crashing into ours and it obtained alot of earths rocks form that crash.

9: When the moon separated from earth and started orbiting it the moon was effected badly from bombardments of meteorites that saved the earth from large holes. Thats why you see huge scar's until today of the moons savior.

10: Hadean eon Climate The atmosphere in the Hadean eon was hot, poisonous and acidic with no oxygen at all. In fact, the temperature was up to 1500 Celsius and higher because of the lava flowing everywhere! Nothing could live, neither plants or animals. Hydrogen and Helium continually leaked from the atmosphere. The rock vapor could have condensed within 2000 years leaving behind

11: hot volatiles which probably resulted into heavy CO2 atmosphere with hydrogen and water vapor.

12: Hadean eon My summary Hadean is the oldest eon and it took place when earth was still young and forming. Meteorites finally stopped crashing on earth during the hadean eon and the eon finally came to a stop when earth started to cool down and life began in around 3.8 billion years ago
