Weathering (breaking down rock) and erosion (transporting rock material) at or near the earth's surface breaks down rocks into small and smaller pieces. These smaller pieces of rock (such as sand, silt, or mud) can be deposited as sediments that, after hardening, or lithifying, become sedimentary rocks.n Earth's surface, wind and water can break rock into pieces (weathering!). They can also carry rock pieces to another place (erosion)!. Usually, the rock pieces, called sediments, drop from the wind or water to make a layer.
The water cycle or hydrologic is a continuous cycle where water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. This repeats again and again in a never-ending cycle.
The hydrological cycle is a closed circulation of the water in its three phases inside the climatic system. It is a closed sequence of natural phenomena, in which the globe provides the atmosphere with water vapour, that afterwards returns in liquid or solid phases to the globe. The natural phenomena that make up the hydrological cycle are: a) the transfer of water, in its gaseous phase, from the globe to the atmosphere, by the evaporation of
