Science Earths Evolution

Tell me what you think plz

1.The Reason why it was not a solid planet yet is because Rocks or asteroids were still being formed. All there was were Dust and Tiny Particles were forming the asteroids. This was probably in the Hadean Era Because it was long ago, That’s Probably why it’s Not in The Earths Geological History. That’s Because It was a Era so long ago all there was in space was Dust and Tiny Particles in the air. Planets were not even in sight because Rocks were not formed yet that’s why we call it in the Hadean Era. And when the sun was formed rock were formed and so much gravity was near the sun that the rocks were clashing into each other and the rocks were so hot Volcanoes started to form. Then a Mars Planet Crashed into earth in the Hadean Period, They think that is how the moon got created. Rock Debris Flew into outer space and earth was spinning out of control and rocks were clashing into together around the earth and the moon was being created at the point. The Earth’s Surface was so hot that nothing would be alive if anyone or anything was on it.

2.The First Animal Life was in the Cambrian Period, That is when most of the major animals came on earth’s land. Than the Ordovician Period came, Water Also came on the earth That’s when most organisms lived in the water and life. Next came the Silurian Period, So much of the earth changes at this Period, Glaciers were melting because earth was getting hotter, no animals were there. Next came the Devonian Period New animals like Vertebrates and Tetrapods came on the earth. Then came the Carboniferous Period, Birds Flew and layed so much eggs so they can go and explore more of the earth’s land. Finally The Permian Period came, This Period was the most largest mass extinction ever to be recorded to destroy 90% of the animals. The most Important event was definitely the Cambrian and the Permian Period.

3.In the Triassic Period, The Sea Floor Started to Move That made the land move closer to each other to make a huge Continent called Pangaea in the Mesozoic Era. In the Triassic and Jurassic Period, Reptiles were born we like to call them Dinosaurs, Like the Permian period animals came in at the Triassic Period because the earth was changing so much and Continents were constantly moving and changing shape. This happened 64 billion years ago. Now the way the Triassic and Jurassic Periods is the same as the Permian Period is because in the Permian Period, Animal life came, Animals life also came in the Triassic and Jurassic Period. Most Reptiles were in the Jurassic Period Because in that time it was a good Habitat for them.

4. There are so many names to call this Era, Cenozoic, Mesozoic, Paleozoic, Proterozoic, and the Archean Period are all the Period’s And other names of the Age of Mammals. The reason why they are the one’s is because these are the Periods of the life of the animals, And then it ended at the end of the Cretaceous Period with the Reptiles (Dinosaurs) Then to this day We have animals that are still alive from all of the Periods that are listed at the top. These are examples of animals that are still alive today: Birds, Crocodiles, Turtles, Sharks, Crabs, Bees, and Lizards Etc. These are animals that are still alive today. Animals that did not make it (Extinct): Qugga, Mammoths, Sea Minks, Mosasaurus, Megalodon, Dinosaurs (Many types), Basilosaurus Etc. People Wish they could go back to these Periods so they can witness them and see what really happened most of it is still in question today. Here are some Other Periods and Eras that may have been with the Age Of Mammals Or with it: Holocene Period, Phanerozoic Period, Triassic, Jurassic, Cretaceous Period, Pleistocene, Miocene, Oligocene, Eocene, These are the events and makings of the Earth: Hadean, Paleoarchean, Mesoarchean, Neoarchean, Paleoproterozoic, Mesoproterzoic, Neoproterzoic. The Earth has survived all of these events and if the earth was not created we would not be standing on it right now.
