The hydrogen cycle Is that process in which the hydrogen moves by means of the water around the earth, being thus an essential part of the chemical and atomic composition of this element.
The hydrosphere obtains hydrogen only from water, an element formed exclusively by the combination of oxygen and hydrogen. During photographic synthesis, hydrogen is produced by the dissociation of water that forms glucose after combing with carbon dioxide.
Plants provide food for herbivores and these animals get glucose and plant proteins only. Hydrogen forms carbohydrates, which is an important source of energy for the living, and these carbohydrates come as food.
There are innumerable types of living beings on earth. All these are basically composed of carbon, nitrogen , Oxygen and hydrogen. Animals obtain these elements of nature and processes such as formation, growth and decomposition normally occur in it.
Several cycles occur as a result of each of these processes, and because of them, they are linked together, establishing a balance.
Phases of the hydrogen cycle
Hydrogen atoms can be stored as a gas or a high pressure liquid. Hydrogen is often stored as liquid hydrogen because it takes up less space than hydrogen in its normal gas form.
When a hydrogen atom joins a strongly electronegative atom that exists in the vicinity of another electronegative atom with a solitary pair of electrons, it makes a hydrogen bond, which forms a molecule. Two hydrogen atoms form a hydrogen molecule, H2 for short.
Hydrogen is a key component of many biogeochemical cycles, including the water cycle, the carbon cycle, the nitrogen cycle and the sulfur cycle. Because hydrogen is a component of the water molecule, the hydrogen cycle and the water cycle are deeply linked.
Plants also recombine water and soil carbon dioxide and atmosphere To form glucose in a process known as photosynthesis . If the plant is consumed, the hydrogen molecules are transferred to the grazing animal.
Organic matter is stored in Floors As the plant or animal dies, and the hydrogen molecules are released back into the atmosphere by oxidation.
1- Evaporation
Most of the hydrogen in our planet is in the water, so the hydrogen cycle is closely related to the hydrological cycle. The hydrogen cycle begins with the evaporation of the water surface.
2- Condensation
The hydrosphere includes the atmosphere, land, surface water and groundwater. As the water moves through the cycle, the state changes between the liquid, solid and gas phases.
Water moves through different reservoirs, including ocean, atmosphere, groundwaters, rivers and glaciers, by physical evaporation processes (including plant transpiration), sublimation, precipitation, infiltration, runoff and Sub surface flux.
3- Transpiration
Plants absorb soil water through their roots and then pump it and supply nutrients to their leaves. The transpiration represents approximately 10% of the evaporated water.
This is the discharge of water vapor from the leaves of plants into the atmosphere. It is a process that the eye can not see, even though the amounts of moisture it implies are significant. It is believed that a large oak can transpire 151,000 liters per year.
Perspiration is also the reason why there is more humidity in places with a lot of vegetation cover. The amount of water that transpires through this process depends on the plant itself, the moisture in the soil (soil), the surrounding temperature and the movement of the wind around the plant.
4- Precipitation
It is the fall of water in any form to the land that gives way to infiltration, which is the process in which water is absorbed in the soil or flows through the surface. This process is repeated over and over again as part of the terrestrial cycles Renewable resources .
Function of Hydrogen on Earth
It is mainly used to create Water . Hydrogen gas can be used for the reduction of metallic ore.
Chemical industries also use it for the production of hydrochloric acid. The same hydrogen gas is required for atomic hydrogen (AHW) welding.
There are a variety of uses for hydrogen. It is the lightest element and can be used as a lifting agent on balloons, although it is also highly flammable, so it can be dangerous. This property and others make the hydrogen suitable for use as fuel.
Since hydrogen is highly flammable, especially when mixed with pure oxygen, it is used as fuel in rockets. These, usually, combine liquid hydrogen with liquid oxygen to make an explosive mixture.
Hydrogen is one of the cleanest fuels because igniting the result is simple water. This is one of the main reasons why there are efforts to create engines that can be powered by the use of this gas.
Although hydrogen is highly flammable, so is gasoline. Although care must be taken, the amount of hydrogen used in a car would present no more danger than the amount of gasoline used.
Despite being one of the cleanest fuels on the planet, its high cost for mass production makes it impossible in the near future to use it for cars for commercial and domestic use.
When hydrogen is heated to extreme temperatures, the nuclei of its atoms will merge to create helium nuclei. This fusion results in the release of a huge amount of energy, called thermonuclear energy. This process is what creates the solar energy .
Electric generators use gas as a refrigerant, which has led many plants to use it as a leak-checking agent. Other applications include processing and production of ammonia.
Ammonia is part of many household cleaning products. It is also a hydrogenation agent used to switch unsaturated unsaturated fats to saturated oils and fats.
