This is a video lesson on the different Natural Hazards and Disasters and how those affects the nature and humankind
Introduction to CBSE Class 11 Social Science Geography Chapter "Natural Hazards and Disasters"
This crucial chapter educates students about the concept of natural hazards and the disasters they can cause when they interact with vulnerable human populations. It covers a variety of natural events, including earthquakes, volcanoes, tsunamis, cyclones, floods, and droughts, each with its own set of causes, mechanisms, and effects on the environment and society.
Students learn about the Indian subcontinent’s susceptibility to various natural hazards due to its unique geoclimatic conditions. The chapter discusses the geological settings that lead to earthquakes and tsunamis, the meteorological conditions conducive to cyclones and floods, and the climatic variations that result in droughts.
The chapter also emphasizes the importance of disaster preparedness and management, introducing strategies for risk assessment, mitigation, and adaptation. It highlights how understanding these natural processes and effective planning can significantly reduce the damage and loss of life during such events.
