Interior of Earth- intrusive volcanic landforms | class 11 NCERT | UPSC prelims

In this final part of our "Interior of the Earth" series, we dive deep into the world of Intrusive Volcanic Landforms (also known as Plutonic Rocks). While extrusive landforms are created on the surface, intrusive landforms are born when magma solidifies within the Earth's crust. This video simplifies complex geological concepts from the Class 11 NCERT Geography textbook, making it an essential resource for school exams and UPSC Prelims preparation. In this video, we cover: [00:17] Difference between Extrusive and Intrusive (Plutonic) Volcanic Landforms. [01:22] What is Magma? Understanding the cooling process in the crust. [03:32] Batholiths: The deep-seated, large dome-shaped granitic bodies that act as magma chambers. [07:33] Lacoliths: Large dome-shaped bodies with flat bases, often resembling composite volcanoes. [14:06] Lapoliths: Unique saucer-shaped horizontal igneous bodies. [15:45] Phacoliths: Magma deposits found at the top of anticlines and the bottom of synclines. [17:41] Sills & Sheets: Horizontal deposits of magma, categorized by their thickness. [17:55] Dykes: Vertical, wall-like structures that served as "feeders" for eruptions like the Deccan Traps.
