GC-07 Latitudes, Equinox, Solstice & Earth’s Motions | Physical Geography | UPSC, PCS, SSC

Welcome to Ankur Srivastava Classes! In this comprehensive General Studies lecture, we explore key concepts of Physical Geography: Latitudinal Lines, Equinoxes, and Solstices. This session is specially structured for aspirants preparing for UPSC CSE, State PCS, and SSC examinations. Understanding how the Earth's tilt, rotation, and revolution create seasonal changes, day-night variations, and sun angles is crucial for mastering world geography. In this video, we break down these astronomical and geographical phenomena into clear, logical, and exam-oriented explanations. Key Topics Covered in This Lecture: Important Latitudinal Lines: Equator, Tropic of Cancer, Tropic of Capricorn, Arctic Circle, and Antarctic Circle. Earth's Motions: Understanding Rotation (day and night) and Revolution (seasons). The Solstices: Summer Solstice and Winter Solstice—positions of the Earth, direct sun rays, and longest/shortest days. The Equinoxes: Vernal (Spring) and Autumnal Equinoxes—equal day and night across the globe.
