Chemical components are made of atoms that have protons and electrons within. Water is a combination of elements and is referred to as a molecule. The elements in question are hydrogen and oxygen that are held by the mechanism of bonding. This is simply the attempt by unstable elements to attain stability or chemical equilibrium. There are three states of matter. The most common state is the liquid since it is exhibited under normal conditions or room temperature.
The majority of the earth is covered by the liquid. The oceans are the reserves and are fed by the rivers. Rivers run down slope from the highlands and mountainous regions. The tributaries combine to form the major river. Wetlands and springs are the other sources but are mostly stagnant. When the springs dry up slightly, bogs are created. The other source that is the deep ground is obtained by the use of boreholes and wells. Wind mills are used to exert pressure on the pumps. The other forms that are gaseous are traced in the atmosphere as vapor. Clouds are also laden with ice crystals.
The hydrological cycle explains the movement of the molecules within the atmosphere. It is thought to begin with the precipitation of the clouds. The precipitants experience free fall and hit the ground whereby they are either drained away in rivers or percolate the deep layers of the soil. A flow also exists within the deep layers of the soil and is generally toward the oceans. The rivers drain in the oceans too. Transpiration and evaporation in the lakes, rivers and oceans occur making the atmosphere rich in moisture. With an existing lifting mechanism the moisture rises and forms clouds that later precipitate. This process is continuous.
Clean water is very vital to both humans and animals. It can be defined as pure and safe with no pollutants for consumption. A difference exists between fresh and clean liquid. Fresh sources are those that have inlets and outlets. Most lakes are fresh sources. The oceans are all salty because they have no outlets. The inlets are very active and manifest as river deltas.
Some human activities introduce harmful chemicals and pathogens into the liquid bodies. This is called pollution and makes it extremely dangerous for animal and human consumption. The most hit are the organisms living in or near the bodies and the plants.
Water borne diseases is one consequent of improper care of the sources. Pathogens present have the capacity of causing harm to the human body. They lead to death outbreaks if proper medication is not provided.
The water borne disease effects of pollution explain why it is important to drink clean water. A process of purification is carried out to make it pathogen free. Boiling has been one of the most common methods employed. Another method is sedimentation but it is not very effective. Desalination is expensive but very effective.
Water is the most important liquid. It is with no doubt that it occupies a very large percentage for both the earth and in the human body. When land lacks water hot deserts occur and the cold ones develop when most of the liquid is in the frozen state. The tundra regions are the most relevant example. For the human body, dehydration occurs when the levels become low.
