Rainfall refers to the precipitation of water droplets from the atmosphere to the ground. Runoff, on the other hand, is the movement of excess water on the ground surface due to factors like saturation or impermeable surfaces. Essentially, runoff is the flow of water that occurs after rainfall.

Water moving along the ground surface. What is that called?
That is called runoff, which occurs when water flows over the ground surface instead of infiltrating into the soil. Runoff can be generated by rainfall, snowmelt, or irrigation.
In which area will surface runoff likely be the greatest during a heavy rainfall?
Surface runoff will likely be greatest in urban areas with large amounts of impervious surfaces like concrete and asphalt, as these surfaces prevent water from infiltrating into the ground. Additionally, areas with steep slopes and compacted soils are also prone to high surface runoff during heavy rainfall events.
What is the differences between rain and rainfall?
Rain is the water droplets that fall from the sky, while rainfall refers to the amount of rain that falls within a specific period of time in a particular area. Rainfall is used to measure the quantity of rain that falls over a given area, typically expressed in millimeters or inches.
How does rain affect runoff?
Rainfall can increase runoff by adding more water to the surface of the ground. If the ground is already saturated or impermeable, the excess water cannot infiltrate and will instead flow over the surface, causing runoff. Factors like soil permeability, slope of the land, and vegetation cover can also influence runoff.
What is the difference between runoff and percolation?
Runoff refers to the water that flows over the land surface and collects in streams, rivers, and lakes. Percolation is the movement of water through the soil layers and into the underground aquifers. Runoff is more surface-focused, while percolation is a subsurface process.
Is the runoff coefficient dimensionless?
Yes, the runoff coefficient is typically dimensionless. It represents the ratio of rainfall runoff to total rainfall, and as a ratio, it does not have any physical units.
What is water that moves across earth's surface after a rainfall?
runoff
What is the water that moves across Earth's surface after a rainfall is what?
Runoff
What is the difference between flood and drought?
Droughts is the lack of rainfall over a period of time, giving an area a deficit in the normal amount of precipitation. Floods is when there is too much rainfall in single or multipule rain event that the terrain cannot manage the runoff causing the rainfall to back up into areas that normally does not have water like road, homes buildings or bridges.
What is the water that moves across the Earth's surface after a rainfall called?
Runoff
What water that moves across earth surface after rainfall is called?
runoff
What is the difference between infiltration and runoff?
infiltration is different because when it happens the rain soaks underground it doesn't fall back into bodies of water like runoff does.
What is a good sentences for runoff?
After heavy rainfall, runoff from the fields flowed swiftly into the nearby river.
That water that moves across Earths surface after rainfall is called what?
runoff
Whats the difference between infiltration and runoff?
infiltration is different because when it happens the rain soaks underground it doesn't fall back into bodies of water like runoff does.
