Comprising of the Paleozoic, Mesozoic and Cenozoic eras, this eon spans 541 million years from the Cambrian Explosion to today.
During the Paleozoic era, complex life started to appear. It took 100 million years for the aquatic plants and animals to migrate to land. Then, another 130 million years later, giant bugs started to appear. 60 million years later, entire coalfields from the Carboniferous Rainforest Collapse Event were set on fire by volcanic activity, causing the Permian-Triassic extinction. The Mesozoic era had begun.
20 million years later, dinosaurs started to appear. They died altogether during the Cretaceous-Paleogene extinction 66 million years ago beginning the Cenozoic era. The mammals started to dominate land. 60 million years later, the Mediterranean Sea drained up, but quickly refilled due to closure and reopening of the Strait of Gibraltar. 6 million years later, humans finally appeared, ending the story of earth's life as we knew it.

Get the Phanerozoic Eon mug.by thealtf4psychic October 16, 2020
Get the Alt+F4 mug.Rodinia is a relatively famous supercontinent that existed towards the end of the Proterozoic Eon. Nevertheless, many people don't know it. It existed from the Stenian period to right before the Cryogenian period encompassing nearly all of the Tonian period.
It was almost exactly on the opposite side of where Pangea formed. It turned inside out during the Cryogenian period to become Pannotia, leaving out exposed rocks that sucked up carbon dioxide, thus causing a snowball earth. Pannotia somehow still didn't make it into the Phanerozoic Eon.
Rodinia wasn't by itself unlike other supercontinents. It had a continent to the west of it as its companion. Made of parts of South America and Africa, this continent was called Congo. While Rodinia turned itself inside out, Congo got caught in between the two halves, completing Pannotia.

Jack who lives in eastern South America: Bruh, my point 800 million years ago was in Congo and not in the rest of Rodinia. Why were the bacteria that lived where I am not able to party with everyone else until 720 million years ago? I feel bad for them.
Kate who lives in western Africa: The bacteria that lived where I am partied with the bacteria that lived where you are for billions of years! Don't feel bad when it comes to paleogeography or paleontology. There are always good things behind terrible extinction events and isolation from everyone else.

Get the Rodinia mug.Silane is a pyrophoric gas. Its chemical formula is SiH4.
It spontaneously ignites when in contact with air. (SiH4+2O2->SiO2+2H2O)
Commonly produced with the following process:
1. Silicon dioxide is burned with magnesium, forming magnesium silicide. (SiO2+2Mg->Mg2Si+O2)
2. The magnesium silicide is placed into hydrochloric acid, forming silane gas, which ignites as it bubbles out of solution. (Mg2Si+4HCl->2MgCl2+SiH4)

Evelyn: I just made silane gas from household chemicals!
Tom: Nice! Did it explode or ignite?
Evelyn: It popped as it bubbled out. What an interesting gas.

Get the qetuosfhkzcbmwryipadgjlxvn mug.If you have learned anything about the geologic time scale, you know the biggest components are the four eons. They can span from just over 500 million years to almost 2 billion years! Most of the eons are subdivided into smaller eras. The eons are: the Hadean Eon, the Archean Eon, the Proterozoic Eon, and the Phanerozoic Eon, which we currently live in.
According to paleontologists, eons don't refer to any long time, but they refer to the four eons in the geologic time scale.

Get the Eon mug.The Russian Soviet Federative Socialist Republic. Also abbreviated as S.F.S.R. (Soviet Federative Socialist Republic) Full Russian form: Российская Советская Федеративная Социалистическая Республика (Rossiyskaya Sovetskaya Federativnaya Sotsialisticheskaya Respublika). Visible on the flag of the S.F.S.R, on the top left as "РсФсР". One of the fifteen Soviet Socialist Republics of the Soviet Union.
Jim: The P.C.F.C.P. used to be the only Soviet Socialist Republic until fourteen states seceded from it as S.S.R.'s too. The remaining of the P.C.F.C.P. became today's Russia.
