What is a runoff in the water cycle definition?
Runoff is nothing more than water “running off” the land surface. Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.
What stage is run off in the water cycle?
Runoff is precipitation that did not get (infiltrated) absorbed into the soil or did not evaporate, and therefore, made its way from the ground surface into places that water collect. Runoff causes erosion and also carry chemicals and substances on the ground surface along to the rivers where the water ends up.
What is run off cycle?
The part of the hydrologic cycle undergone by water between the time it reaches the land as precipitation and its subsequent evapotranspiration or discharge through stream channels.
What do you mean by run off?
1 : a final race, contest, or election to decide an earlier one that has not resulted in a decision in favor of any one competitor. 2 : the portion of precipitation on land that ultimately reaches streams often with dissolved or suspended material. run off. verb. ran off; run off; running off; runs off.
What are the factors that affect runoff?
Meteorological factors affecting runoff:
- Type of precipitation (rain, snow, sleet, etc.)
- Rainfall intensity.
- Rainfall amount.
- Rainfall duration.
- Distribution of rainfall over the watersheds.
- Direction of storm movement.
- Antecedent precipitation and resulting soil moisture.
What is the relationship between aquifer and run off?
Runoff is the water that is pulled by gravity across land’s surface, replenishing groundwater and surface water as it percolates into an aquifer or moves into a river, stream or watershed.
What causes run off?
Runoff occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds. Glaciers, snow, and rain all contribute to this natural runoff. Runoff also occurs naturally as soil is eroded and carried to various bodies of water.
What is the difference between run off?
“Run off” can almost always be changed to “run away” without making a statement false. A specific use of “run away” is actually closer to the meaning of “run off”, and that is when a child or teenager runs away from their parents for a long period of time (days, months, years or permanently).
What is runoff water cycle?
runoff cycle. The part of the hydrologic cycle involving water between the time it reaches the land as precipitation and its subsequent evapotranspiration or runoff.
What are facts about runoff?
Runoff, run-off or RUNOFF may refer to: RUNOFF, the first computer text-formatting program Runoff or run-off, another name for bleed, printing that lies beyond the edges to which a printed sheet is trimmed Runoff or run-off, a stock market term Runoff curve number, an empirical parameter used in hydrology
What is the rain cycle?
Rain water runs over the land and collects in lakes or rivers, which take it back to the sea. The cycle starts all over again. The water cycle is the journey water takes as it moves from the land to the sky and back again. It follows a cycle of evaporation, condensation, precipitation and collection.
