Beginning of EarthTemperature: 8000F
Comets forming the Earth.
Earth was molten.
Water was beginning to form on EarthStarting to cool and solidify.
Earth is covered in water vaporWater world: 90% (green oceans and iron)
Atmosphere: CO2 (thick and red)
Continents began to formOceans become dominated.
Granite appears. (salt water + basalt)
Granite PlanetContinents formed everywhere.
Species dominated: Stromatolite
Blue PlanetO2 is in the water. (Oxidized out the iron)
Continents are moving.
Rodinia is formedFormed over the south pole and is blocking the currents.
Snowball EarthMass Extinction killed tiny organisms. (95%)
Rodinia breaking apartVolcanic eruptions are breaking Rodinia apart.
Cambrian"Boom of life."
Ice melts on Rodinia and is broke apart.
Ozone begins to form and marine life begins.
OrdovicianSponges, corals, and primitive fish lived in the waters.
Red and green algae was in the water.
SilurianLandmasses were low and sea levels were rising.
Shortest period in Paleozoic Era.

PennsylvanianWidespread swamps formed coal.
Animals on landAmphibians/reptiles, huge insects on land.
Pangaea forming and tropical swamps.
PermianEnded in the largest mass extinction that Earth ever had.
Severe extremes of climate and environment. South was cold and arid.
TriassicFirst period of the Mesozoic Era.
Life outside the oceans began to diversify.
PangaeaVolcanic eruptions happened and killed 95% of extinctions.
O2 levels increased and dinosaurs are evolved.
JurassicJurassic period started.
Middle period of Mesozoic Era.
Pangaea breaks upVolcanic activity breaks up Pangaea.
High O2 levels/warm temperatures.
CretaceousThe last of the three periods of the Mesozoic Era.
New groups of mammals and birds.
DiamondsPangaea is apart and diamonds erupt in the surface.
TertiaryFirst period of the Cenozoic Era.
Dinosaurs extinctEnormous asteroid hits on Earth.
75% of species including dinosaurs go extinct.
Mammals dominateSwiss Alps/Himalayas from colliding continents.
HimalayasHimalayas and many other mountains began to form.
Grand CanyonGrand Canyon was being formed.
