Originating in the Mediterranean region, these disturbances travel eastward, affecting areas like northern Bangladesh and southeastern Nepal. While they induce low pressure systems, resulting in rainfall in plains and snowfall in mountains, their intensity has… Read More »
Alfred Wegener’s Pioneering Continental Drift Theory In the annals of geophysics, a significant turning point arrived in 1912 when Alfred Wegener, a German geophysicist, introduced the Continental Drift Theory (CDT). Wegener’s theory reshaped our understanding of the Earth’s history and geological transformations. Wegener’s ground-breaking theory posited the existence of a colossal supercontinent named Pangaea, a… Read More »
Plate Tectonics Theory : Unveiling Earth’s Dynamic Puzzle The theory of Plate Tectonics, a cornerstone of modern geology, emerged in 1967 through the insights of McKenzie and Parker, followed by Morgan’s elucidation in 1968. It harmoniously incorporates the pre-existing notions of continental drift, convection currents, and seafloor spreading. According to this captivating theory, Earth’s lithosphere… Read More »
