During the water cycle, the main accomplishment is that "water is redistributed around Earth." The water cycle involves processes such as evaporation, condensation, precipitation, and runoff, which continuously move water in various forms throughout the atmosphere, surface, and underground.
While the water cycle does play a role in filtering and purifying water naturally, it does not guarantee that all water is cleaned and safe to drink. Additionally, new water molecules are not made in the water cycle; rather, water is continuously cycled and reused. Therefore, the correct answer is that water is redistributed around Earth.
