The wind.
The process of evaporation moves water from the Earth's surface to the atmosphere, where it condenses into clouds. Precipitation, such as rain or snow, returns water from the atmosphere to the Earth's surface. This cycle is known as the water cycle.
Surface water refers to bodies of water present above the Earth's surface, such as rivers, lakes, reservoirs, and streams. This water is in constant motion, either flowing downstream or circulating within a body of water due to external forces like wind or temperature gradients. Surface water plays a critical role in supporting ecosystems, human activities, and the hydrological cycle.
Approximately 97% of the Earth's surface is covered by salt water.
They are called rills. Rills are small channels that form on sloping land when water flows over the surface, cutting small ditches as it moves downhill.
Water moves continuously between Earth's surface and the atmosphere through the process of evaporation and condensation. Water evaporates from surfaces like bodies of water, soil, and plants, rising into the atmosphere as water vapor. Then, as the water vapor cools and condenses, it forms clouds and eventually falls back to the surface as precipitation, completing the continuous cycle of water movement.
Water which moves over the earths surface after having precipitated (rain, snow, etc) is known as runoff. Most rivers get the majority of their water from precipitation runoff.

it is water cycle
70% or 80% of water covers the earths surface
water condenses and when there is enough water vapor is condensed it rains so it may transpire or evaporate once more
3/4 of the earth's surface is water.
