Water can be described as a transparent, tasteless, odorless, and nearly colorless chemical substance. Chemical? Yes! And Its chemical formula is H2O, meaning that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bond. And any taste, odor or color in the water has simply been caused by the solvents and solubles in the water
Water exists in different forms; Rain, Fog, Clouds, Ice, Snow, Steam or Water Vapor; and moves continually through atmospheric circulation of evaporation, transpiration, condensation, precipitation and runoff.
This water movement, also known as the hydro logical
cycle, describes the continuous circulation 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, freshwater, saline water and atmospheric water is variable depending on a wide range of climatic . The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, and in doing so, the water goes through different forms: liquid, solid and vapor.
The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment. These heat exchanges influence climate.
The evaporative phase of the cycle purifies water which then replenishes the land with freshwater. The water cycle is also essential for the maintenance of most life and ecosystems on the planet.
Water is essential for life. WATER IS SOUL OF THE EARTH
