In terms of water, the earth is a closed system, so water isn’t added or removed from earth; it’s simply transformed, transported, and recycled. Hydrologic cycle. The hydrologic cycle, also known as the water cycle is a way of describing the material flow of water throughout the Earth. This series of steps describes how water moves across the Earth and changes form.
