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.
Water Cycle. Water rains down to the earth on stormy days. It gets soaked up into the ground. Water movement is part of the water cycle. The water cycle is important to all living things on the earth! There are other cycles in your life. Your daily routine is a cycle. You wake up. You go to school. You ride the bus home. You go to soccer practice. You eat dinner. You go to bed. These events are part of a cycle. This cycle repeats itself every weekday. The water cycle is also a set of repeated events that happen over and over again. Evaporation, condensation, precipitation, and collection are the repeated events in the water cycle.
