Glaciers and ice caps contain the largest amount of freshwater on Earth, followed by groundwater, lakes and rivers, and soil moisture.

Evaporation is the process by which water evaporates from the Earth's surface and condenses in the atmosphere.

Climate, topography, and geology are all major factors influencing the distribution of water resources on Earth.

Transpiration is the process by which plants release water vapor into the atmosphere.

Industrial waste, agricultural runoff, and sewage discharge are all major causes of water pollution.

Filtration, disinfection, and reverse osmosis are all processes used to remove impurities from water.

Water scarcity, water pollution, and climate change are all major challenges facing water management in many parts of the world.
