Question

what effects does construction of building and roads have on water percolation throug the soil

Answer 1

construction of roads and buildings have made the earth a concrete jungle. the concrete does not allow the water to percolate so the level of ground water table is also going down.

Answer 2

Answer:

Rainwater that percolates through the soil collects above the bedrock and this water is called water table. Water cannot percolate into the cement. The increasing construction of buildings and roads has reduced the soil cover. This results in decrease in water table.
