Major Mountains & Rivers of the World

Mountains and rivers are among the most frequently tested physical geography topics in SSC CGL. Understanding the world's major mountain ranges — their location, continent, and notable peaks — gives you an edge across both Tier-I and Tier-II papers. Alongside mountains, rivers define civilisations and carry enormous SSC weightage; knowing each river's length, source, drainage basin, and outflow mouth is essential. The questions in this chapter require you to link a mountain peak to its range, or a river to its continent, so read all tables and key points carefully.
