Abstract

From the creation of our mother planet, Earth about 4.5 billion years ago, the planet has undergone a number of simple and complex processes to attain the present day scenario. Though it looks like a simple process and a suitable and stable place for life to live with, many more continuous and complex processes are taking place, making it a more active and dynamic planet in our Solar system. Since the beginning of the planet from a super collision effect, it has restlessly evolved in its internal and external characteristics through various active processes. Tracking the history, we can get a glimpse of its dynamical changes on the basis of many central hypotheses, which were observed, proved and analytically described. As many of them can be attributed towards its dynamic changes, the basic and major ones which really explain the processes are Continental Drift hypothesis, sea floor spreading, Paleomagnetism and Polar Wandering Path; and collectively above all others. Though these theories explain the same consequences and results, they have undergone different evidences and experiments to reach in the last consequences. As an active planet, the continuous dynamical changes of Earth can be traced on the basis of vivid and conceptual analysis of the above hypotheses.
