Answer 1

The total water of the world remains constant. Option iv

The water cycle is a perpetual process involving water on Earth. Water may fluctuate in form (liquid, vapor, or ice) and travel between various reservoirs (oceans, atmosphere, rivers, and groundwater), but over geological time scales, the overall amount of water on Earth stays largely constant.

Evaporation, condensation, precipitation, runoff, and other activities are part of the water cycle, which helps move water around and re-distribute it among different reservoirs without causing a net loss or gain.
