Earth's cycle moves water from one reservoir to another. this cycling of materials is one of earth's dynamic processes.

The answer that is most suitable is earth's hydrologic cycle.

Water does not remain locked up in the oceans,  icecaps, groundwater systems , or the atmosphere. Instead water is continually moving from one reservoir to another. This movement of water is called the hydrologic cycle.

Although water in the hydrologic cycle is constantly in motion, it never leaves the earth. The earth is nearly a "closed system" like a terrarium. This means the earth neither gains nor loses much matter, including water.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
