🌍 World Distribution of Volcanoes 🌋
Volcanoes are not randomly scattered across the Earth. Instead, they are closely linked to weaker zones of the Earth’s crust, where tectonic activity is high. They often occur near plate boundaries and are associated with earthquakes. 🔥 The Three Major Volcanic Belts 1️⃣ Circum-Pacific Belt – The Ring of Fire 🔥🌊 📍 Location: Encircling the…
🌍 Plate Tectonic Theory: The Science Behind Earth’s Dynamic Crust
In the world of geology, Plate Tectonic Theory (PTT) is like the “Grand Unified Theory” that explains how continents move, oceans form, mountains rise, and earthquakes shake our planet. It is based on two key ideas:✅ Seafloor Spreading – Proposed by Harry Hess, explaining how ocean floors expand.✅ Continental Drift – Proposed by Alfred Wegener,…
🌊 Sea Floor Spreading Theory – Harry Hess (1960)
In the 1950s, undersea mapping shattered the myth that ocean floors were flat and featureless. Instead, scientists discovered rugged landscapes with vast mountain chains and deep trenches. 🔍 Key Observations from Seafloor Mapping: These discoveries set the stage for Harry Hess’ revolutionary theory of Seafloor Spreading in 1960. 🚀 What is Seafloor Spreading? Harry Hess…
Wind Eroded Arid Landforms
Let’s say you are standing in the middle of a vast desert, under the blazing sun. The air is hot, and strong winds are constantly brushing past you, carrying tiny sand particles. Over thousands of years, these sand particles have sculpted some of the most fascinating and dramatic landforms you can imagine. Today, we’ll take…
Wind and Aeolian Landforms
Imagine yourself standing in the middle of the Thar Desert in Rajasthan. The sun is blazing, the air is dry, and the only thing that seems to have life is the strong wind blowing continuously across the barren landscape. This wind, seemingly invisible but immensely powerful, is one of the most dominant forces that shape…
William Morris Davis & His Concept of Landscape Development
William Morris Davis, the father of geomorphology, introduced a fascinating theory—the Geographical Cycle of Erosion, also called the Cycle of Erosion. According to Davis landforms undergo sequential changes through time (passing through three stages of youth, mature and old). Over time, the battle between these two forces leads to a systematic transformation of landforms through…
