4: What was occurring | In the Priscoan Eon also known as the hadean the earth just formed. And plants were starting to grow. Also in that time the Earth was starting to melt and harden. volcanoes make this happen and there was a lot of volcanoes.
6: Plants and Animals | In that eon the Earth was forming so plants and animals didn't exist. Even because of the harsh climate.
8: Climate | In the Priscoan Eon the climate was very dangerous. Earth was usually being hit by meteorites. The climate was very hot and the surface was molten because of the volcanoes. The climate was so hot that even oceans didn't exist. At first there was no atmosphere but when things started to cool and meteorite hits decreased an atmosphere started to be created. but that atmosphere was very hot, poisonous and acidic. there was even no oxygen, so nothing could live there.
10: Rocks | There weren't plants and animals in that time but there were rocks. There was a lot of volcanoes and the surface was molten. The rocks were mostly metamorphic.

Priscoan EonThe Priscoan Eon began about 4.6 billion years ago.It was the earliest part of the Precambrian. It extendedfrom the origin of the earth to about 4,000 million yearsago. Also there was no life in that period.That time period was much more different then the present day. For example the Earth was much bigger then now. It shrinked because Earth's crustmelted and hardened many times. In the Priscoan Eon rocks were mostly metamorphic. That’s the information of the Priscoan Eon.
