Earth: Making of a Planet is a documentary film showing the making of Planet Earth from rocks and dust to our current home, beginning 4.5 billion years ago.
Scientists usually describe the timeline of earth’s history in 4 different stages: Hadean, Archean, Proterozoic and Phanerozoic.
The Hadean eon (4.6 – 4 billion years ago) sets the beginning of earth’s history, where our planet was a giant, red hot, boiling sea of molten rock – a gigantic magma ocean.
It has frequent volcanic activity and a hellish environment. The heat had been generated by the repeated high speed collisions of much smaller bodies of space rocks that continually clumped together as they collided to form this planet.
As the collisions tapered off the earth began to cool, forming a thin crust on its surface.
As the cooling continued, water vapor began to escape and condense in the earth’s early atmosphere.
Clouds formed and storms raged, raining more and more water down on the primitive earth, cooling the surface further until it was flooded with water, forming the seas.
During the Archean eon (4 – 2.5 billion years ago) Earth’s atmosphere was composed of volcanic and greenhouse gases.
This environment catalysts Prokaryote life, the first form of life, through a process known as abiogenesis.
The continents of Ur, Vaalbara and Kenorland may have been formed around this time.
As life forms continuously more complex life, Earth shapes itself towards the Proterozoic Eon (2.5 billion – 541 million years ago).
In this eon Eukaryotes emerge – this life is a more complex form of life which include some forms of multicellular organisms.
Bacteria begins producing oxygen, shaping the third and current of Earth’s atmospheres. Plants, later animals and possibly earlier forms of fungi form around this time.
Study suggests the early and late phases of this eon may have undergone “Snowball Earth” periods, in which all of the planet suffered below-zero temperatures.
The early continents of Columbia, Rodinia and Pannotia may have formed around this time, in that order.
The Phanerozoic eon (541 million years ago – to our present times) sees complex life, including vertebrates, and how they begin to dominate the Earth’s ocean in a process known as the Cambrian explosion.
Pangaea forms and later dissolves into Laurasia and Gondwana. Gradually, life expands to land and all familiar forms of plants, animals and fungi begin appearing, including annelids, insects and reptiles.
Several mass extinctions occur, among which birds, the descendants of dinosaurs, and more recently mammals emerge.
