RafaRainfall 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.
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.
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.
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.
