15 Facts About The Earth
greetings extraterrestrials today we will be turning into primitive egg technology presented by the human called Sam to learn 101 facts about us number.
- one so when did this whole earth thing kick off then according to smart science he people the earth was formed around 4.6 billion years ago from a cloud of gas dust and rock orbiting the Sun eventually some of this debris and detritus clump together into a legit planet because gravity that legit planet is now known as ER Oh earth sorry yes earth that's that's all I meant to say.
- number two life has existed on earth between 75% to 80% of its existence life popped up pretty soon after Earth had cooled down enough
- NUMBER # 03
- number three we know this because the oldest confirmed fossils single-celled microorganisms are approximately 3.5 billion years old
- number four the period of Earth's history spanning between 1.8 billion and 800 million years ago is remarkable for being well unremarkable the fossil record during this time period is a bit bland to the extent that this period is now known as the boring billion Wow harsh
- that beingsaid things were indeed happening in the boring billion including the best thing s X yes scientists believe that sexual reproduction first occurred during this period fossils from roughly 1.2 billion years ago showed that certain species of algae had begun to form specialized sex cells such as spores mmm musty spores
number six eventually I decided that being a boiling hot ball of going rock was so hundreds of millions of years ago and decided to get supercooled instead it's thought that the emergence of oxygen stretched methane from the air which prompted the entire planet to freeze over into a so-called snowball earth.
number seven this period of time was the longest and coldest ice age in history beginning around 1715 million years ago and sticking around for 120 million freezing years did exist 715 million years ago someone call that self we need to get at the bottom of this.
number eight tracks found in Scotland indicate the existence of huge fridge sized scorpions scarring around 330 million years ago it's not known for certain whether these animals known as hippo top Taurus ever made it on land or preferred to stick to the bonny proto Scottish seas.
number nine other massive insecty type things included Megan er er a giant dragonfly like creature which lived around 300 million years ago they had wing spans as large as 65 centimetres making them some of the largest insects to have ever existed on plane .
Earth number 10 around 300 million years ago all of Earth's landmasses were joined together as one huge supercontinent called Pangea as such there was also one giant ocean called Panthalassa.
around 280 to 230 million years ago Pangaea decided that it didn't want to be a supercontinent anymore and divide it into two smaller supercontinents known as Gondwana and larysa these two enormous land masses move and split even further like your parents after a divorce until we eventually ended up with the continents we have today.
to be fair to them the continents never stopped moving and are still doing so today they're just doing it as anincredibly slow pace which is pretty much the same speed that fingernails grow.
- NUMBER # 14
- Ice Age in particular led to the second worst mass extinction ever known as the Ordovician Silurian which is also species when dr. who 85% of all marine species were wiped out - which is like which is you know a lot.
- NUMBER # 15
- earth's largest ever extinction event aka the permian-triassic extinction event aka the great dying is thought to have been caused by massive volcanic eruptions in Siberia roughly 95% of marine and 70% of terrestrial life was wiped out about 252 million years ago which is about any hashtag triggered by the release of more than 200 billion gallons of molten lava across what is now known as the Siberian traps in Russia the eruption is thought to have lasted for a million years which here that extinct.
