HISTORY OF EARTH - THE ANCIENT TIME TO NOW

HISTORY OF EARTH 

                🌎 The history of earth begins from it's formation. Till the date many many scientist's could not find that the how Earth had formed. Different hypothesis are given about the earth formation. So it also imagined that it is formed due to the small part separation of Sun. Later it became cold. Initially it is proved from the hard core present at the centre of the Earth.

Initially I want to elaborate that in the past 4.5 billion years ago the Earth is formed. Earth like the gift for the solar system. Earley the earth is hot from the separation but it became cold in order to compared the past time. Many things keep changing in the earth due to the suitable temperature and the medium distance. It is exactly located at the perfect place enhance to maintain the suitable making nature of the Earth.
Earth is really unique planet than other planet. It ws only the planet where the every necessary thing like climatic condition has present in the past. Many revolutions are occured in the Earth forming or introducing the new animals and plants. Earth is revolutionized by passing through different eras or the different period of time.

Era:-

             Era describes the long duration about several millions of years. After the Earth formation, the Earth is revolutionized by the following eras.

i) Precambrian Era :-

                      It was the duration between 4.6 billion to 542 million years ago. It is the earliest part of the earth formation. This era is the era of formation of single cell organisms. This era had studied by the fossil that are buried under the process of sedimentation.

ii) Palezoic Era :-

                    It was known as the age of fishes, amphibians and invertebrates. It was the duration between 542 to 252 million years ago. In this era many invertebrates, amphibians animals are formed, first reptiles are formed or the developed. The era is studied by the large and big fossil that are found in the seas and in the mining time. Exactly from the era the life of animals and plants had started.

iii) Mesozoic Era :-

                      It had revolutionized between the duration of 252 to 60 million years ago. From this era, flowering plants are firstly introduced,birds are firstly introduced and the dinosaurs are dominant. It is also called the era of dinosaurs because in this the whole earth is captured or ruled by the dinosaurs. Big birds are newly borned. It is also called highly developed era because the animals species that are developed in this era are found upto now also except dinosaurs.

iv) Cenozoic Era :- 

             It has the time scale of 66 million years ago to the running present time. At firstly extinction of dinosaurs happened. It had hypothesized that at the time of dinosaurs extinction the earth is totally destroyed and the new Earth had formed like a newly born baby. In this era humans are introduced from jungle to the better human life. The world is now running in this era.

               The Earth is presenting new modern world with the developed humans. Firstly technology are introduced two million years ago. From the early of 16th century the Earth is modernised rapidly with the new invention and the laws that follows by the whole universe. For example: gravitational force by Newton, the radio by the marconi, telescope by the Gallie Gallelio,etc. The humans present the new inventions that are needed for the modern society. From the history people used to agrigate for their lifestyle but it keeps decreasing due to the business activities in the modern world. Now the most advanced technology is the computer development with the advance function. It is making the works easier to do. The future will be going to be handled by the modern technology that are keep making in the society.

              In one positive impact there are many negative impacts. With the growing technology, the Earth would suffered by different unwanted irrational things. Many corrupted things are happend already in the earth like the world war and the pandemic diseases. In developing modern technology people are crossing their limit. They are developing the over limit that the mother Earth cannot manage or the handled it. One example of it is that the billionear Elon musk wanted to establish the Earth like nature in the Mars instead of making the earth beautiful and suitable by investing money in it. They are inventing many affected things that can destroyed the Earth.

           From the history of origin of the Earth to the present world many essential thing are invented but many unnecessary and unwanted things are also invented like the atom bomb, and the establishment of the hunger polluters industries. It is the great thing that the Earth is formed and we are living in it passing our beautiful life from the many generations.

             At lastly, Earth is everything for the living organisms. Prevent it also for the future generation. Prevent the earth in order to inventing the modern technology that affected the Earth.
