Hi! I am Manuela and today we are going to have a travel through the time.
PRECAMBRIAN ERA
First, two planets crashed and this created our planet Earth.
Then all was lava.Auch! so hot!!
In this comic we are going to see all the eras of the earthI hope you like it!!!
Formation of oceanic and continental layers, first oceans appears with liquid water.
Ohh to coold!!!
This happened 4.5 billion years ago, it is the largest period of all the eras. The crash produced the planets and our solar system.
Presence of first bacterias around 3.400 millions years ago.
We are cianobacterias!!
In this part of the Precambrian era there was a big movement of magma and volcanos.
Multi celular organisms
I survived yeyy!!
After the lava and the volcanos, all the planet Earth became frost, when the planet thawed it appared the first ocean with liquid water.
The bacterias lived in colonies
OMG THEY ARE TALKING
With the climate changes of the late Precambrian, a lot of multicelular organisms died, but some of those survived by evolution.
Better weather!
PALEOZOIC ERA
Pangaea Supercontinent was formedLater the algae arrived, then the plants, the insects and finally the fishes, those are the oldest vertebrates.
Jurassic
TRIASSIC
MESOZOIC ERA
A fish continued evolvingIchthyostega appeared.
JURASSIC
Second frost ageAfter a lot of time the Earth had the second frost age, in which a lot of species died and another survived and began to evolve.
CRETACEOUS
Too cold again.
Reptiles/dinosaursFirst dinosaurs branched off from reptiles.
DinosaursGolden age of the dinosaurs.
SupercontinentContinents were close to their present location.
A metheorite is going to crash the Earth.
CENOZOIC ERA
Too many bugs!!
Modern EarthWhen the metheorite landed in the Earth, the impact separated all the pangaea supercontinent.
The age of mammals
Dinosaur extinctionWhen metheorite crashed, 75% of life on the Earth disappeared.
It is too big!!
Grass When the Earth cooled down, grass appeared, which is very important because with the grass the bugs came.
The first apes
The first aquatic mammals
The first homosapiens
Descubrimiento
Época colonial
Conquista
Colonización
Los españoles llegaron a América en 1550.
Actualidad
Cuando los españoles llegaron, a los indígenas no les gustaron sus nuevas reglas y protestaron por ello.
Los indígenas perdieron y los españoles los colonizaron. y la colonización termino en el año 1810.
Han pasado millones de años y la tierra y sus habitantes siguen evolucionando. solo si somos consientes de nuestros actos podremos cuidar al planeta, para que así siguientes generaciones puedan ver: el oso de anteojos, el jaguar, las tortugas carey, el tití cabeciblanco, el manatí del caribe y muchas más.
