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.
Practice questions
Which example shows that soil can decide special vegetation even when climate is favourable?If a high rainfall area has unstable slopes and rapid erosion, what should be the priority for vegetation conservation?If vegetation belts are seen changing with altitude on a map, which conclusion is most correct?If climate is warm and humid and soil is nutrient-rich, what vegetation condition is likely?If rainfall is very low but farming has expanded through irrigation, what will be the effect on natural vegetation?In which condition will small leaves benefit plants more than broad leaves?Which option does not correctly match factor and result?If rainfall is same in an area but one part has eroded soil, why can vegetation be less there?In which condition can mangroves be studied as a combined example of vegetation factors?If flowering time of plants is changing due to climate change, which two factors will be most directly linked?If an area has waterlogging, oxygen-poor soil and salinity, what challenge will plants face?In which condition can decline of natural vegetation increase migration of wildlife?Which factor can most directly affect depth and spread of plant roots?If an area is at low latitude but very high mountainous, what idea is necessary in vegetation decision?Which option gives the correct reason for local study in conservation?If soil, rainfall and temperature are favourable but continuous construction occurs in the area, what will happen to vegetation?In which condition does lack of light create a pressure different from lack of water?If vegetation is sparse in an area, which analysis will be most correct?If soil has low water holding capacity, what effect will plants face despite equal rainfall?In which condition is biodiversity more likely to be low?
