Every day is Earth Day at USGS! 🌍 If every drop of water on, in, and above the Earth was gathered into a single ball, it would be surprisingly small compared to the planet. While 71% of Earth’s surface is covered by water, that represents only a thin layer. So how much water is there on Earth? 💧 96.5% is saline water in oceans 💧 2.5% is found as freshwater 💧 30% of the freshwater is stored in the ground 💧 69% of that freshwater is stored in glaciers and ice caps 💧 about 1% is accessible in lakes and rivers Earth's water supply is finite and constantly moving through the water cycle. Understanding why the tiny sphere of water shown is critical helps put Earth Day into perspective. While water is abundant, easily accessible freshwater is a scarce, precious resource that is the lifeblood of our planet.
