Detailed explanation-1: -The ocean holds 97% of the total water on the planet; 78% of global precipitation occurs over the ocean, and it is the source of 86% of global evaporation.
Detailed explanation-2: -The hydrologic cycle is a conceptual model that describes the fluxes of water between the oceans, surface water bodies (lakes, rivers, and streams), groundwater in subsurface aquifers, the atmosphere, and the biosphere.
Detailed explanation-3: -All water on Earth resides in one of the three compartments of the hydrologic cycle: the atmosphere, the land surface, and the subsurface. A water budget is an account-ing of water stored within and water exchanged among some subset of the compartments, such as a watershed, a lake, or an aquifer.
Detailed explanation-4: -As condensation occurs and liquid water forms from the vapor, the water molecules become more organized, and heat is released into the atmosphere as a result.
