Geography Notes: All Types of Valleys
🌄 Geography Notes: All Types of Valleys 🔰 What is a Valley? A valley is a low landform between hills or mountains, often with a river or stream flowing through it. Valleys are formed by erosion or tectonic activity. 📚 Types of Valleys (Based on Formation) 1. 🏞️ V-Shaped Valley Formation : By river erosion (vertical erosion). Shape : Narrow bottom, steep sides. Location : Young mountain regions. Example : Upper course of the Ganga river, Himalayas. Diagram : Looks like the letter "V". 2. 🏔️ U-Shaped Valley Formation : By glaciers moving down mountains. Shape : Wide and flat bottom, steep sides. Location : Glaciated mountain regions. Example : Kashmir Valley, Yosemite Valley (USA). Diagram : Looks like the letter "U". 3. 🌋 Rift Valley Formation : Due to faulting (tectonic plates pulling apart). Shape : Steep walls, flat bottom. Location : Tectonic plate boundaries. Example : Great Rift Valley (Africa), Narmada and Tapti Valleys (I...
