ABSTRACT
The hydrosphere is all the Earth’s waters. It includes liquid water, water vapour, ice and snow. Water in the oceans, in rivers, in lakes and ponds, in ice sheets, glaciers, and snow fields, in the saturated and unsaturated zones below ground, and in the air above ground is all part of the hydrosphere. Some people set the ambits of the hydrosphere to exclude the waters of the atmosphere.
