Sources of Water
Earth's water is mainly divided into surface water (rivers, lakes, ponds, oceans) and underground water, with oceans holding the vast majority of salty water.
Rivers and Their Stages
Rivers originate in mountains as glaciers, flow fast through valleys, and finally merge into the sea or ocean, depositing rich soil called silt.
Oceans and Seas
Oceans are huge, continuous bodies of saline water covering about 71 percent of the Earth's surface, playing a major role in the water cycle and climate.
Water Conservation
The careful and economical use of water resources to prevent scarcity, ensuring that future generations have access to clean drinking water.
Rainwater Harvesting
A sustainable method of collecting, storing, and reusing rainwater from rooftops or surfaces before it runs off to recharge groundwater.
