What is the country's history?

Planet Earth has created about 4.6 billion years (4,567,000,000 years ago), in a fully molten state, from the protoplanetary debris orbiting the newly formed sun. It is assumed that another, smaller planet of Mars, called Theia, has been formed in the same orbit as the Earth around this time. For 28 - 34 million years (4.527 - 4.533 billion years ago) orbital oscillations caused Theia to affect the country, released a large amount of bark and created a month. This is the best contemporary theory of the moon formation called the hypothesis of a giant impact. The oceans began to form during the first part of the Hadean, maybe 4.2 million years ago. The Earth has cooled from the molten state and created a solid peel within just 100 - 150 million years. Heavier elements such as iron Anikl dropped to the core of the ground and left smaller quantities on the surface. The whole planet was distinguished into layers. During the second part of Hadean, about four billion years ago, a primitive life appeared, perhaps as a small self -religious springs DNAor RNA by means of chemicals rich in energy (heterotrophy).

Another era of the country's history, known as Archhean Eon, lasted from 3.8 billion to 2.5 billion years. Molecular dating studies indicated that the latest universal common predecessor (Luca) lived in contemporary life during the early part of Archaean, 3.5 billion years ago. It is about the same time with the development of the first autotrophs. Autotrof is an organism capable of using photosynthesis to extraction of energy from sunlight. Oxygen is a waste product is photosynthesis and around this time was released in large quantities. At that time, the de -acid was poisonous to most organisms, with a massive extinction and transformation of atmospheric and superficial chemistry, called an "oxygen disaster".

sentences that follow the Hadean and Archan are Proterozoic ("primitive era of life"), which lasts from 2.5 billion to just 542 million years, paleozoic ("oldThe era of life "lasting 251 to 65 million years ago, and 251 years ago, and the last years, and recently (recent Era of Life", and "half of the life" that lasts from 542 to 251 million years (recent era (the middle era of life "(recent era of life" The life of the "(recent era of life" (the recent era of life "(life. Life" lasting from 65 million years to the present. In the Proterozoic, with the exception of the last few tens of millions, primitive microbes have been the only known forms.
