Limiting development on floodplains is effective because it

allows floodplains to absorb water with little harm to homes

Balance in the water cycle means that

the avg annual precip over Earth equals the amount evaporate

the lowest point to which a stream can erode its channel

The water cycle is the

unending circulation of Earth's water supply

the land that contributes water to a stream

the water table intersects the ground surface
