Key Topics to Revise

1

Cyclones

  • Cyclones are violent rotating windstorms that originate over warm ocean waters
  • In India, cyclones primarily originate in the Bay of Bengal due to intense heating and humid air masses
  • Bay of Bengal is surrounded by land on three sides, making it prone to cyclone formation
2

Floods

  • Floods occur when river water volume increases due to heavy rainfall or ice melting, causing overflow
  • Uncertainty of monsoon rainfall is a major cause of floods in India
  • Silt accumulation in rivers reduces water-carrying capacity leading to floods
3

Landslides

  • Landslides involve land mass sliding down slopes from mountains or hills
  • Include stones, mud, and debris along with sliding land mass
  • More destructive in steep mountainous regions, especially Himalayas
4

Coastal Erosion
