Water covers a larger fraction of the planet, the earth is made up of over seventy-two percent water. Such a large amount of liquid is distributed in different forms from one place to another over the earth. There exists a larger amount of water that cannot be depleted by any method. Besides being used in all operations such as washing, cooling hot objective, or processing food it is still available each day. Water is a fluid with unique features making it change state from gas, liquid, or solid and vice-versa. Such a property causes the inability of making these fluids to be depleted, when used in one state it changes to another state.
This fluid occurs on land, beneath the crust, or as gaseous vapor in the sky and is limited. The earth is a sealed system, indicating that tiny matter such as water, cannot get away, or penetrates the atmosphere. Water that had been on earth since it was formed many years ago is still present now. However, the earth recycles those liquid supplies through a water cycle. Despite the quantity of water accessible on the planet, only a small proportion is usable by humans. A large fraction of water cannot be consumed, the consumed amount is less than one percent and is attained from streams.
Larger portions of water are found beneath, such as soil moisture or water tables. Fluid from beneath provides water for everyday flow in rivers even in the absence of rainfall. Water available for human consumption is both ground and surface water. The water cycle of the earth includes a variety of sources that are discussed below. Large water holes such as oceans are fed by smaller rivers that collect water from inland regions of our planet. They are important in saving water on the planet, they enable evaporation on a larger scale.
The gaseous water rises to the sky where it is compressed and forms rainfall. That rain provides water to plants and refills the ground moisture which has to evaporate due to harsh sun heat. Surface waters are easily obtainable by humans and are noted as a popular source of this fluid. This comprises all water bodies on earth such as springs, tributaries, downpours, lakes, and dams. They constitute a large proportion of domestic and industrial uses of water. Agriculture farmers use such water when watering plants and feeding animals. In addition to that, it is used in the extraction of minerals in mines.
Oceans hold over eighty percent of water, but, due to the ocean’s high salt, the water is not good for drinking. Various approaches have been employed to remove salt from such water because it is costly. Saline water is majorly used in mining procedures and power production. Rivers and springs are the flowing surface water, it occurs due to the force of gravity which draws water from high ground to lower lands. They obtain their water from either groundwater or runoff. Rivers can obtain this water from the underground when they cut it into the water table at a high altitude.
Runoff flows from high altitude collects to form tributaries that mergers form a river. Streams create channels on the earth’s surface which are vital to drain the excess water to the ocean. This action prevents flooding of the surface during heavy precipitation in flat areas.
Groundwater is found beneath the earth’s crust, the soil is permeable and allows the flow of this liquid in the soil. These waters are salty which arises due to high pressure, heat, and minerals. As this liquid penetrates the rocks, it dissolves salts that increase its salinity. Precipitation in cold regions leads to the formation of solid water like glaciers. Melting of these water bodies can change ocean level greatly, they should be protected from intense heat due to climate change.
Such fluid is a valuable commodity that deserves to be protected at any cost. Catchment areas such as forests are to be protected from being cleared down by firewood. Protection of catchment areas preserves all forms of water, including groundwater, that occurs beneath the crust. Even though there is plenty of water on the planet, it is a vital role to protect its sources to evade the effects related to water insufficiency.
