This is a gully erosion!

The water cycle is made of obviously water. it is always in a constant moving change and/or state. Where does all the Earth’s water come from? Primordial Earth was an incandescent globe made of magma, but all magmas contain water. Water set free by magma began to cool down the Earth’s atmosphere, until it could stay on the surface as a liquid. Volcanic activity kept and still keeps introducing water in the atmosphere, thus increasing the surface- and ground-water volume of the Earth. The Water Cycle will include evaporation(from the sun), ice and snow can automatically sublimate into vapor, transpiration(soaked up from plants and soil), condensation(rises into air), condensation(where vapors rise to cooling temperatures), precipitation(cloud particles collide,grow,and fall from the sky), infiltration( deep into ground to replenish or aquify), surface runoff(water flows over the ground into rivers and lakes), groundwater(seeps back into surface water-bodies), absorbing and even emerging into springs.

River waters are used for drinking and even irrigation.Rivers are a major source to humans and animals. Watersheds are imporatnt because they're affected by the flow on top of the earths surface. "As part of the water cycle, ground water is a major contributor to flow in many streams and rivers and has a strong influence on river and wetland habitats for plants and animals."

Flooding occurs when the volume of water exceeds the capacity of the channel. Erosion is a gravity driven process that moves solids (sediment, soil, rock and other particles) in the natural environment or their source and deposits them elsewhere. In our case it is transported due to water. Deposition is the geological process by which material is added to a landform or land mass. Deposition is eventually building up new sediment.
The Water cycle teaches us how our planet sustains water on our earth and how we can obtain fresh water as well. We must continue to find ways to have freshwater as someday some people believe we will run out of fresh water. What will happen when it is gone?
