BIOGRAPHY OF THE EARTH, FORMATION OF
THE CONTINENTS
-A galaxy in particular we are
interested in, what we call today MILKY WAY.
-Over time, some masses stayed closer
and they were forming what we now know as galaxies. 
-Today, the Earth has a different aspect as when it
was formed around 4,470 millions of years ago
-Is known as BIG BANG, a huge explosion that is continually expanding.
-Everything was in constant changing, the fire from the center of the Earth continued coming out of the volcanoes and pieces of the crust moved causing gigantic earthquakes.
-Billions of years ago, the entire universe was a huge
hot, dense mass, and about 13.8 billion years ago, that mass exploded.
-
-For millions of years the Earth's crust has been fragmented into several pieces, called tectonic plates, which have been displaced because they belong to the lithosphere.
-
-In 1912, the German scientist Alfred Wegener formulated the hypothesis that all the continents were once together. He called it Pangea and then, they were separated through a process that he called Continental drift
b. Asthenosphere: the upper layer of the earth's mantle, below the lithosphere.

-The Paleozoic era ("ancient life"): encompassed 312 million years ago and that's when the Earth was divided into several continents.
-The Phanerozoic, on the other hand, covers 560 million years, has three eras, and comes to the present, the Holocene.
-The Mesozoic era ("intermediate life"): it is also known as the age of dinosaurs, saw with its hot climatic diversification and multiplication of animal and plant life on earth.
-
-The Cenozoic era ("new life"): It covers the last 65 million years, until today. In this period, there is the collision of Asia with India and Arabia with Eurasia, giving rise to the Alps and the Himalayas. More complex forms of life appear mammals, hominids,Homo sapiens and the current human being.
-In geological eras, you are in periods and you are in epochs The vast geological history of the Earth is divided into two great eons:
