In all of the above! The water cycle describes how water travels from the oceans, evaporating into the atmosphere and back to Earth in the form of rain, and during this process the water is stored in all those places.
-The water cycle is the flow of water in its different states as it passes through different parts of the planet Earth, including the atmosphere and the surface.
-Water is stored on Earth during the water cycle as a liquid in the form of groundwater, rivers, seas, and oceans and as a solid in the form of ice and glaciers. This accumulation of water that is stored in bodies of water enables the sustenance of life on Earth.
