	The water molecule is one of the lightest molecules that exist (although there are several that are lighter), and it's certainly the lightest molecule that forms a [[liquid]] on Earth. Water forms a liquid at room [[temperature]] because it has such a strong [[electric dipole]]. Water has just about the strongest dipole moment of any molecule because of it's small size. This dipole nature means that the hydrogen in the water is strongly attracted to [[electron]]s around the oxygen, called [[hydrogen bonding]]. This hydrogen bonding of water is not just what makes water a liquid—but what makes it a powerful [[solvent]] through these electric interactions. This allows many important [[chemical reaction]]s to occur in water.

	Water has a huge effect on Earth's [[climate]] and is a major factor in [[weather]] as well (see [[climate vs weather]] for the difference). Weather often includes [[precipitation]] like [[rain]], [[snow]], and [[hail]]. [[Cloud]]s are made largely of small water droplets or frozen crystals. Water vapour is also the [[greenhouse gas]] with the biggest effect on the [[temperature of the Earth]], and it has an amplifying effect on the [[global warming]] from [[carbon dioxide]]. In other words, water vapour itself doesn't drive climate change, however, amplifies the effects since more ~~CO2~~ means more water vapour will be in the atmosphere.

	Too little water causes [[drought]]s, which are a problem. Too much causes [[flood]]ing, which is also a problem.

	As seen in Figure 1, there's a large amount of water on Earth, but most of it is [[saline]]—commonly known as salt water. This water is not suitable for drinking, thus it is not consumed by humans. Most of the [[fresh water]] needed for life is locked up in the [[cryosphere]] ([[glacier]]s and permanent [[snow pack]]s), while the majority of available fresh water is stored in [[groundwater]]. The smallest of the three bubbles on the picture is the surface water; the water that humans can directly access at the Earth's surface. Since there are such small amounts of this consumable water available, water [[pollution]] is a concern. In some parts of the world, the lack of access to clean, fresh water is a serious issue.

	<onlyinclude>'''Water''' is a [[molecule]] made of one [[oxygen]] and two [[hydrogen]] [[atom]]s.

	As seen in Figure 1, there's a large amount of water on Earth, but most of it is [[saline]] - commonly known as salt water. This water is not suitable for drinking, and thus it is not consumed by humans. Most of the [[fresh water]] needed for life ~~is locked up in [[groundwater]], while a fair amount~~ is locked up in the [[cryosphere]] - [[glacier]]s and [[snow pack]]s. The smallest of the three bubbles on the picture is the surface water; the water that humans can access. Since there are such small amounts of this consumable water available, water [[pollution]] is a concern. In some parts of the world, the lack of access to clean, fresh water is a serious issue.

This water is not suitable for drinking, and thus it is not consumed by humans. Most of the [[fresh water]] needed for life is locked up in the [[cryosphere]] - [[glacier]]s and permanent [[snow pack]]s, while the majority of available fresh water is stored in [[groundwater]]. The smallest of the three bubbles on the picture is the surface water; the water that humans can directly access at the Earth's surface.

	The water molecule is one of the lightest molecules that exist (although there are several that are lighter), though it's certainly the lightest molecule that forms a [[liquid]] on Earth. Water forms a liquid at room [[temperature]] because it's such a strong [[dipole]]. Water has just about the strongest dipole moment of any molecule because of it's small size. This dipole nature means that the hydrogen in the water is strongly attracted to [[electron]]s around the oxygen, called [[hydrogen bonding]]. This hydrogen bonding of water is not just what makes water a liquid. These electric interactions make water a powerful [[solvent]]. This allows many important [[chemical reaction]]s to occur in water.

	Water exists in three phases on earth, liquid water which is the most abundant, [[solid]] water, ~~affectionately~~ referred to as [[ice]] and [[water vapour]] which is the [[gas]]eous form.

	==Water and the Climate==		==Water and the Climate==
	Water has a huge effect on Earth's [[climate]] and is a major factor in [[weather]] as well (see [[climate vs weather]] for the difference). Weather often includes [[precipitation]] like [[rain]], [[snow]], and [[hail]]. [[Cloud]]s are made largely of water ~~vapour~~. Water vapour is the [[greenhouse gas]] with the biggest effect on the [[temperature of the Earth]], and it has an amplifying effect on the [[global warming]] from [[carbon dioxide]], in other words, it responds to climate change and makes it stronger than it would otherwise be rather than driving climate change.

	Too little water causes [[drought]]s, which are a problem. Too much causes [[flood]]ing, which is also a problem. One of the biggest concerns about [[climate change]] is that it will affect how much water will be in different parts of the world. This has been summed up as "the wet will get wetter and the dry will get drier". Please see [[climate change impacts on water]] for more details. Completely separate from [[climate change]], there's quite a bit of concern about [[water pollution]] including [[acid rain]].		Too little water causes [[drought]]s, which are a problem.
