Lake
8 linksArea filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake.
Area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake.
The majority of lakes on Earth are freshwater, and most lie in the Northern Hemisphere at higher latitudes.
Water
8 linksInorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent ).

The physical properties of seawater differ from fresh water in some important respects.
Groundwater
8 linksWater present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations.
Water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations.
Groundwater makes up about thirty percent of the world's fresh water supply, which is about 0.76% of the entire world's water, including oceans and permanent ice.
Water cycle
6 linksBiogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.
Biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.
The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water (salt water) and atmospheric water is variable depending on a wide range of climatic variables.
Wetland
5 linksDistinct ecosystem that is flooded by water, either permanently or seasonally (for weeks or months).
Distinct ecosystem that is flooded by water, either permanently or seasonally (for weeks or months).
The water in wetlands is either freshwater, brackish or saltwater.
Water resources
6 linksWater resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water.
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water.
97% of the water on the Earth is salt water and only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps.
Seawater
3 linksWater from a sea or ocean.
Water from a sea or ocean.
Seawater is denser than both fresh water and pure water (density 1.0 kg/l at 4 C) because the dissolved salts increase the mass by a larger proportion than the volume.
River
3 linksA river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river.
Iceberg
2 linksAn iceberg is a piece of freshwater ice more than 15 m long that has broken off a glacier or an ice shelf and is floating freely in open (salt) water.
Water pollution
3 linksContamination of water bodies, usually as a result of human activities, so that it negatively affects its uses.
Contamination of water bodies, usually as a result of human activities, so that it negatively affects its uses.
It can be grouped into surface water pollution (either fresh water pollution or marine pollution) or groundwater pollution.
