Rivers and seas
The hydrosphere is made up of all the water on the Earth. This includes the water in the seas, oceans, rivers, lakes, polar ice caps, groundwater and the water vapour in the atmosphere. Water is the most abundant resource on the Earth. It can be found in a solid (ice), liquid (water) or gaseous (vapour) state. Water is the main component in the water cycle, but it is not an unlimited resource.
