Geography
Factors Affecting Vegetation
वनस्पति को प्रभावित करने वाले कारक
In this Class 9 Geography topic from “Natural Vegetation and Wildlife,” students learn why different regions support different kinds of plants. They examine how temperature, rainfall, sunlight, soil, relief, altitude, and slope influence the growth and distribution of natural vegetation. The topic also helps them connect vegetation patterns with climate and landforms, and understand how human activities can alter plant cover. These ideas build a clear foundation for reading India’s varied landscapes and vegetation regions.
