GEOLOGY

Detailed explanation-1: -Usually, storm water runoff flows overland or is discharged by storm sewers into nearby waterways or treatment devices. Waterways may be stream beds, rivers, or lakes. Treatment devices include rain gardens, swales, infiltration practices, wet ponds, and bioretention systems.

Detailed explanation-2: -Only about a third of the precipitation that falls over land runs off into streams and rivers and is returned to the oceans. The other two-thirds is evaporated, transpired, or soaks (infiltrates) into groundwater. Surface runoff can also be diverted by humans for their own uses.

Detailed explanation-3: -surface runoff (water flows above the ground’s surface), interflow runoff (water flows underground just below the land’s surface), and. base flow runoff (water flows deep within the ground’s saturated zone).

Detailed explanation-4: -Water moves into the atmosphere through evaporation and transpiration and returns to the Earth through precipitation. the ground and is stored underground as ground water. Runoff: water flows along the surface of the Earth. usually end up back in the oceans.
