Approximately 71% of the Earth's surface is covered by water. This vast expanse includes oceans, seas, rivers, lakes, and glaciers. Oceans account for the majority of this coverage, containing about 97% of the planet's total water supply. Freshwater sources, such as rivers and lakes, make up a tiny fraction of the total water volume. The vast amount of water on Earth is vital for supporting life, regulating climate, and influencing weather patterns. The remaining 29% of the Earth's surface consists of land, including continents and islands, making access to freshwater resources essential for human survival and ecological balance.
