Introduction to Continents and Ocean Basins Continents and ocean basins being fundamental relief features of the globe are considered as ‘relief features of the first order’. It is, therefore, desirable to inquire into their mode of possible origin and evolution. Different views, concepts, hypotheses and theories regarding the origin of the continents and ocean basins … Read more
Earthquakes and INFRASTRUCTURE, and it can also cause landslides and liquefaction. Tsunamis, which are large waves caused by earthquakes, can also cause widespread damage. Volcanoes are formed when magma, or molten rock, rises to the surface of the Earth. Magma can rise to the surface through cracks in the Earth’s crust, or it can erupt … Read more
The Unseen Forces: Exploring Endogenic Processes and Their Impact on Earth The Earth, a dynamic and ever-changing planet, is a testament to the interplay of internal and external forces. While the sun’s energy and atmospheric processes drive the external forces, the Earth’s own internal heat and pressure fuel the endogenic processes. These processes, often hidden … Read more

Most of the knowledge we have about Earth’s deep interior comes from the fact that seismic waves penetrate the Earth and are recorded on the other side. Earthquake ray paths and arrival times are more complex than illustrated in the animations, because velocity in the Earth does not simply increase with depth. Velocities generally … Read more
The Acid Rain Problem: Understanding the Sources of Atmospheric Pollution Acid rain, a phenomenon that has plagued the environment for decades, is a complex issue with far-reaching consequences. It refers to the deposition of acidic components, primarily sulfuric and nitric acids, from the atmosphere onto the Earth’s surface. While natural sources contribute to some extent, … Read more
