Endogenic forces originate within Earth (volcanism, tectonics), building landforms. Exogenic forces act on surface (weathering, erosion), wearing them down through agents like wind and water.
Through continuous circulation—evaporation, condensation, precipitation, and runoff—it redistributes water among oceans, atmosphere, and land, sustaining all life systems.
Insolation is incoming solar radiation. It heats the atmosphere unevenly, creating temperature zones, driving winds, and enabling the hydrological cycle.
Humidity is atmospheric moisture content. Precipitation is any form of water falling from clouds—rain, snow, hail—occurs when humidity reaches saturation point.
Biosphere includes lithosphere, hydrosphere, atmosphere. Biomes are large ecological areas (tundra, forest) defined by climate and dominant vegetation within biosphere.
A natural event (earthquake) becomes a disaster when it causes widespread human, economic, or environmental loss exceeding local coping capacity.
Agriculture supplies food grains. Food security means consistent physical and economic access to sufficient, safe, nutritious food for all citizens.
FDI brings capital, technology, and efficiency. In transport, it improves ports/roads; in trade, it boosts exports and integrates India into global supply chains.
Human development expands people’s choices and well-being. Key indicators: long & healthy life (health), knowledge (education), decent living standard (income).
SDGs (Goal 6: clean water; Goal 11: sustainable cities) directly link environmental protection with improved sanitation, reducing open defecation and waterborne diseases.
