PreCambrian Time (544 MYA- 4.6 MYA)
Earth formed- The earth started as a dust ball,rock, and ice. It grew bigger from gravity. Dust, rock, and ice nearby got pulled together and changed into thermal energy, creating the Earth.
Oceans Formed- All water evaporated into vapor and condensed into rain. It eventually accumulated and formed oceans.
Oldest Rock- They formed when molten lava rose and cooled from the cracks in the sea-floor. They were found in Canada.
Prokaryotic Cell (Simple Cell)- They are simple cells because they are missing a nucleus brain (bacteria).
Eukaryotic (Complex Cell)- They are complex cells because they make up all known global life, has a nucleus brain (algae).
Jellyfish like animal (Multicellular)- They have tiny stinging cells. Some stings can be deadly. There are two types of cell divisions, Mitosis and Parent Cell.
Arthropods- Insects, Spiders, crabs, and lobsters. The earliest arthropods on earth developed 550 million years ago. They consist of many cells.
First Mass Extinction- The Final stages of PreCambrian time were marked by global ice age. They led to many extinctions.
