Endogenic Processes are processes that originate within the Earth. They include: Plate tectonics Mountain building Earthquakes VolcanoesVolcanoes Magma intrusions Metamorphism Hydrothermal activity Endogenic processes are responsible for the formation and evolution of the Earth’s surface. They are also responsible for the distribution of Natural Resources, such as oil, gas, and minerals. Endogenic processes are processes … Read more
Alfred Wegner was a German Meteorologist in the early 1900s who studied ancient climates. Like most people, the jigsaw puzzle appearance of the Atlantic continental margins caught his attention. He put together the evidence of ancient glaciations and the distribution of fossil to formulate a theory that the continents have moved over the … Read more
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
The Forces of Tension: Shaping the Earth’s Surface Through Orogenic Processes The Earth’s surface is a dynamic tapestry, constantly reshaped by the relentless forces of plate tectonics. Among these forces, tension plays a pivotal role, driving the creation of dramatic landscapes and influencing the distribution of resources. This article delves into the fascinating world of … Read more
Evolution and Geomorphology of the Indian Subcontinent About 140 million years ago the main landmass on Earth was concentrated together in a super continent called Gondwana which started to break up in four tectonic plates; African, Antarctic, Australian and Indian plates. The rifting is thought to be caused by the rising of a … 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
Understanding Earthquakes: A Comprehensive Guide Earthquakes, those sudden and often violent shifts in the Earth’s crust, are a powerful reminder of the dynamic nature of our planet. These seismic events can cause widespread devastation, leaving behind shattered landscapes, collapsed buildings, and a trail of human suffering. Yet, understanding earthquakes is crucial not only for mitigating … Read more
The Earth’s Magnetic Shield: A Journey into Geomagnetism The Earth, our home planet, is not just a rocky sphere floating in space. It possesses a hidden, yet vital, force field: the geomagnetic field. This invisible shield, generated deep within the Earth’s core, protects us from the relentless barrage of charged particles emanating from the Sun, … Read more

The Earth’s Shifting Skin: A Journey Through Plate Tectonic Theory The Earth, our planet, is a dynamic and ever-changing entity. Beneath our feet, a hidden world of immense power and movement constantly reshapes the surface we inhabit. This dynamic force, known as plate tectonics, is the driving engine behind earthquakes, volcanoes, mountain ranges, and even … Read more
