- Ice caps, groundwater, rivers, lakes
- Water cycle: evaporation, condensation, precipitation
Water Scarcity
- Uneven distribution — Rajasthan vs Kerala
- Overuse in agriculture (flood irrigation)
- Pollution of rivers — industrial and domestic waste
- Groundwater depletion in Punjab, Haryana
Conservation
- Rainwater harvesting — stepwells, rooftop systems
- Watershed development
