Questions about the origin and nature of earth and the life on it have long preoccupied human thought and the scientific endeavor. deciphering the planet's history and processes could improve the ability to predict catastrophes like earthquakes and volcanic eruptions, to manage earth's resources, and to anticipate changes in climate and geologic processes. Evolution of earth. • the planet earth initially was a barren, rocky and hot object with a thin atmosphere of hydrogen and helium. • the earth has a layered structure. • from the outermost end of the atmosphere to the centre of the earth, the material that exists is not uniform. • from the surface to deeper depths, the earth’s. There are three stages in the evolution of the present atmosphere. the first stage is marked by the loss of primordial atmosphere. in the second stage, the hot interior of the earth contributed to the evolution of the atmosphere. finally, the composition of the atmosphere was modified by the living world through the process of photosynthesis.
