Water cycle: Transforming into tangible form

Water is one of the most active elements in the natural geographical environment, playing a crucial role in shaping the surface of the Earth. The hydrosphere participates in the transfer of matter and the flow of energy on a global scale, while promoting circulation. The water resources on Earth not only include mineral water, bound water, and water deeply hidden in the lithosphere, but also include oceans, rivers, lakes, groundwater, atmospheric water, and ice and snow, all of which are important components of the Earth's hydrosphere. The water cycle plays an indispensable role in maintaining the functioning of terrestrial and aquatic ecosystems.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Water, as the most active factor, participates in the shaping of natural geographical environments, and the hydrosphere participates in the exchange and circulation of global materials and energy. In addition to the chemical and bound water present in various minerals, as well as the water stored deep in the lithosphere, the water on Earth is also composed of oceans, rivers, lakes, groundwater, atmospheric moisture, and ice and snow. Water cycle: Various forms of water on the Earth's surface are constantly transforming into each other. The process of water circulating in gaseous, liquid, and solid forms between land, oceans, and atmosphere is called the water cycle.

Ocean current: refers to the water with a relatively stable velocity that follows a regular pattern along a certain direction.
