The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation. [2] 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.
The common myth often refers to the draining action of flush toilets and bathtubs. In fact, rotation is determined by whatever minor rotation is initially present at the time the water starts to drain, as the magnitude of the coriolis acceleration is negligibly small compared to the inertial acceleration of flow within a typical basin.

The water cycle including human activities. Water cycle management is a multidisciplinary approach relating to all planning, developmental, operational and tactical decisions to influence the water cycle. Most importantly water cycle management is used to ensure availability of clean water for designated use, and to ensure safe release of ...
Water is important to life because it is an effective solvent, capable of dissolving solutes such as sodium and chloride ions or other small molecules to form an aqueous solution. Once dissolved in water, these solutes are more likely to come in contact with one another and therefore take part in chemical reactions that sustain life. [33]
24] The computer science course was recently updated and moved from Group 5 (as an elective course) to Group 4, becoming a full course, from first examinations in 2014. The structure and assessment of the course has changed to greater emphasize problem solving rather than Java program construction. [ 25 ]
Water can be polluted, abused, and misused but it is neither created nor destroyed, it only migrates. There is no evidence that water vapor escapes into space." [12]: 26 Every year the turnover of water on Earth involves 577,000 km 3 of water. This is water that evaporates from the oceanic surface (502,800 km 3) and from land (74,200 km 3).
Perennial lake is a lake that has water in its basin throughout the year and is not subject to extreme fluctuations in level. [ 36 ] [ 49 ] Playa lake is a typically shallow, intermittent lake that covers or occupies a playa either in wet seasons or in especially wet years but subsequently drying up in an arid or semiarid region.
Scientific terminology is the part of the language that is used by scientists in the context of their professional activities. While studying nature, scientists often encounter or create new material or immaterial objects and concepts and are compelled to name them.
