Satellites based on application can be categorized as follows: Earth Observation satellite-> Starting with IRS-1A in 1988, ISRO has launched many operational remote sensing satellites. Today, India has one of the largest constellations of remote sensing satellites in operation. Currently, *thirteen* operational satellites are in Sun-synchronous orbit – RESOURCESAT-1, 2, 2A CARTOSAT-1, 2, 2A, 2B, … Read more
The Coriolis Force: A Silent Conductor of Wind Movement The wind, a seemingly chaotic force that whips across the globe, is actually governed by a complex interplay of factors. One of the most crucial, yet often overlooked, influences is the Coriolis force. This force, arising from the Earth’s rotation, subtly steers winds, shaping weather patterns … Read more
Faulting and the Rise of Fault Mountains: A Journey into Earth’s Dynamic Landscape The Earth’s surface is not a static entity. It is a dynamic system constantly reshaped by the relentless forces within its core. One of the most dramatic and visible manifestations of this dynamism is faulting, a process that fractures the Earth’s crust … Read more

Orogenic or the mountain-forming movements act tangentially to the earth surface, as in Plate tectonics. Tensions produces fissures (since this type of force acts away from a point in two directions) and compression produces folds (because this type of force acts towards a point from two or more directions). In the Landforms so produced, … Read more
The Subtle Dance of the Tides: Understanding Neap Tides The rhythmic rise and fall of the ocean, the ebb and flow of the tides, is a mesmerizing natural phenomenon that has captivated humans for millennia.
