The hydrosphere refers to all the water on Earth, encompassing various forms such as liquid, solid (ice), and vapor. It includes oceans, seas, rivers, lakes, glaciers, groundwater, and atmospheric moisture. The hydrosphere interacts with other Earth systems, including the atmosphere, biosphere, and geosphere, and plays a fundamental role in regulating climate and supporting life.
Oceans and Seas
Cover about 71% of the Earth’s surface and contain about 97% of the planet's total water. Oceans regulate global climate by absorbing and redistributing heat from the sun. Ocean currents (like the Gulf Stream) move warm and cold water around the planet, influencing weather patterns. Freshwater (Lakes, Rivers, Groundwater)
