Even if the Earth ac- The nebula from which our Solar system is supposed to have been formed, started its collapse and core formation some time 5-5.6 billion years ago and the planets were formed about 4.6 billion years ago. It is an alternative to the Big Bang model of the evolution of the universe. The atmospheric matter has the least density. During the cooling of the earth, gases and water vapour were released from the interior solid earth. One of the earlier and popular arguments was by German philosopher Immanuel Kant. It is known as Nebular Hypothesis. Modern scientists refer to the origin of life as a kind of chemical reaction, which first generated complex organic molecules and assembled them. It is undoubtedly clear that initially the earth or even the atmosphere of the earth was not conducive for the development of life. Hoyle and Lyttleton: The planets of the solar system have an originated from the expanding gases obtained from the explosion of a supernova. Like the origin of the earth, there have been attempts to explain how the moon was formed. Immanuel Kant, the German philosopher, pre­sented his treatise entitled ‘The General Natural His­tory and Theory of the Heaven or the Essay on the Working and Mechanical Origin of the Entire Uni­verse on the Basis of Newtonian Laws’ in 1755. It is also called expanding universe hypothesis. Origin of Earth By- S M Zaki Ahmad 2. Mathematician ; Laplace revised it in 1796. The candidates will find here important questions related to the origin and evolution of the earth which indeed will help in IAS Prelims Exam and State PCS Exams. A large number of hypotheses were put forth by different philosophers and scientists regarding the origin of the earth.

This tells us that the oceans are as old as 4,000 million years. Considered one of the founding father of the field of space plasma physics. (iii) Within 300,000 years from the Big Bang, temperature dropped to 4,500 K (Kelvin) and gave rise to atomic matter. The universe is very old – almost 13 billion years old. During the cooling of the earth, gases and water vapour were released from the interior solid earth. Image of Binary Star Hypothesis - Russell. These clumps continue to grow into even denser gaseous bodies, giving rise to formation of stars. The earth has a layered structure. The rainwater falling onto the surface got collected in the depressions to give rise to oceans. It suggests that about 1370 crore (13.7 billion) years ago, all matter and energy in the universe was concentrated into an area smaller than an atom. Eventually, growing nebula develops localised clumps of gas. It talks of a singular huge explosion unimaginable in physical terms. This is far from the present day picture of the earth. Origin of earth or theories of the evolution of the universe are below: Early theories: Nebular Hypothesis; Binary Theory or Planetesimal Hypothesis; Modern Theory: Big bang theory. This is called chemical evolution which cannot occur under present environmental conditions upon earth. inanimate matter into living substance. Also, the origin of many phenomena like earthquakes, volcanoes, tsunami etc are linked with the structure of earth's interior. It states that at some moment all of space was contained in a single point of very high-density and high-temperature state from which the universe has been expanding in all directions ever since. Most of them are much larger than the terrestrial planets and have thick atmosphere, mostly of helium and hydrogen. Although it is the most studied planet, it cannot be completely understood in isolation. Modern scientists refer to the origin of life as a kind of chemical reaction, which first generated complex organic molecules and assembled them. Binary theories. As per the human development report 2011, the per Capita Gross National Income in India stood at Rs.3,468 for the year 2011. The universe became transparent. This allowed heavier materials (like iron) to sink towards the centre of the earth and the lighter ones to move towards the surface. Explain the purpose of Juno Mission and discuss how it would be useful in understanding about formation of Earth. Earth was hot glowing ball of white hot gases. However, one of the hypotheses namely “Nebular Hypothesis” given by Immanuel Kant and revised by Laplace became more popular.. The study of landforms, their processes, form, and sediments at the surface of the Earth (and sometimes on other planets) is known as Geomorphology. The most popular argument regarding the origin of the universe is the Big Bang Theory. Planets were believed to be formed out of a cloud like material associated with Sun. Sometime around 3,800 million years ago, life began to evolve. It is undoubtedly clear that initially the earth or even the atmosphere of the earth was not conducive for the development of life. In 1838, Sir George Darwin suggested that initially, the earth and the moon formed a single rapidly rotating body. Scientists believe that though the space between the galaxies is increasing, observations do not support the expansion of galaxies. Due to gravitational pull a gaseous tide was raised on the surface of the sun. As the earth cooled, the water vapour released started getting condensed. As a result, a cigar-shaped extension of material was separated from the solar surface. Continue your investigation of the moon’s origin. One of the earlier and popular arguments was by German philosopher Immanuel Kant. Gaseous tide detached when star move away. Hydrogen and helium were the gases which intially formed the earth's atmosphere. This document is highly rated by UPSC … Particles of gases were compressed together, giving off heat. The theory states that the planets were formed by the accumulation of extremely small bits of matter planetesimals that revolved around the sun. Planets were believed to be formed out of a cloud like material associated with Sun. Get top class preparation for UGC right from your home: Get detailed illustrated notes covering entire syllabus: point-by-point for high retention. (ii) At the Big Bang the “tiny ball” exploded violently. However, scientists in later period took up the problems of origin of universe rather than that of just the earth or the planets. Buffon was the first scientist to give a scientific explanation regarding the origin of the earth and solar system in 1754. As the star came nearer, the tide increased in size. The Big Bang Theory is the most accepted theory regarding the origin of the planet earth and the existence of different life forms on it. What should you understand about the interior of the earth? Mathematician Laplace revised it in 1796. The expansion continues even to the present day. Planetesimal Hypothesis, a theory of the origin of the solar system. The Big Bang theory is the prevailing cosmological model for the birth of the universe. Alternatively, the first four are called Terrestrial, meaning earth-like as they are made up of rock and metals, and have relatively high densities. 1. A galaxy starts to form by accumulation of hydrogen gas in the form of a very large cloud called nebula. Assumptions 1. NCERT Notes: The Origin And The Evolution Of The Earth [Geography Notes For UPSC] NCERT notes on important topics for the IAS aspirants. 17 The “Big Six” Elements of Early Earth. There are three stages in the evolution of the present atmosphere. Understanding the basic structure of earth is very important to learn higher concepts well. Our Solar system consists of eight planets. This is not in accordance with the fact. STEADY STATE THEORY. Sun and planets coalesced out of a vast cloud of gas and dust. Explain the purpose of Juno Mission and discuss how it would be useful in understanding about formation of Earth. There were many scientists who studied the fossils and performed experiments to postulate their versions of the theory … 3. (i) In the beginning, all matter forming the universe existed in one place in the form of a “tiny ball” (singular atom) with an unimaginably small volume, infinite temperature and infinite density. This hypothesis explains well some of the observed phenomena relating to solar system. Earth - Earth - Development of Earth’s structure and composition: The origin of Earth in its present form has long been the subject of intellectual interest, but since the mid-20th century scientists have made particularly significant advances both in concepts and in measurements. According to Buffon, origin of the solar system is the result of an accident between the Sun and a … Particles of gases were compressed together, giving off heat. The last phase in the evolution of the earth relates to the origin and evolution of life. It can be assumed that life began to evolve sometime 3,800 million years ago. Earth formed around 4.54 billion years ago by accretion from the solar nebula. The Human Origin Project. Nebular Hypothesis: • Proposed by German philosopher Immanuel Kant and revised by Laplace in 1796. One of the earlier and popular arguments was by German philosopher Immanuel Kant. Davis postulated his concept of the origin of coral reefs in 1914-18 and revived the subsidence theory as pos­tulated by Darwin and others. H.N. Finally, the composition of the atmosphere was modified by the living world through the process of photosynthesis. The difference between terrestrial and jovian planets can be attributed to the following conditions: (i) The terrestrial planets were formed in the close vicinity of the parent star where it was too warm for gases to condense to solid particles. Jan 10, 2021 - NCERT Textbook Chapter 2 - The Earth, Class 11, Geography UPSC Notes | EduRev is made by best teachers of UPSC. He presented several physiographic evidences in support of subsidence theory and to explain hither to unsolved several problems related to the formation of coral reefs. The formation of stars is believed to have taken place some 5-6 billion years ago. The early atmosphere of the Earth was what we would now consider a quite hostile environment. (1999) With reference to the theory of Plate tectonics, explain the origin and growth of the Young Fold Mountain systems of the World. January 08 . Jovian planets were formed at quite a distant location. Early Theories. Oparin-Haldane theory is also called chemical theory or naturalistic theory. It talks of a singular huge explosion unimaginable in physical terms. • The early atmosphere largely contained water vapour, nitrogen, carbon dioxide, methane, ammonia and very little of free oxygen. Now, if you start inflating the balloon, the points marked on the balloon will appear to be moving away from each other as the balloon expands.
