Answer:
The correct options are;
1) Increased Runoff
2) Decreased infiltration
3) Decreased water in underground
4) Increased chance of flooding
Step-by-step explanation:
Paving involves the building of a flat surface made of stones laid down in a pattern consisting of materials such as concrete, asphalt, bricks and tiles and other related materials
A water shed drains waters from streams and rainfall to outlets such as lakes, reservoirs, streams as well as underground, ground water.
Paving on water shed can lead to the collection of pollutant from the atmosphere and car tire debris and other forms of pollutants that would otherwise have been decomposed and made use of by soil bacteria.
These collected pollutant become washed into major water bodies where due to their pollute content and high speed of run off, negatively impacts on the aquatic ecosystem.
1) As the watershed has been made impervious to water, collected and flowing water from rain and other water bodies all move in a direction along the plane influenced by gravity such that the runoff is increased
2) The paving material with which pavement are made are generally impervious, leading to decreased infiltration
3) As the water that lands on the paved (watershed) surface and other water bodies are not absorbed by the ground beneath the pavement, there will be decreased water underground
4) Flooding is caused when water overflows over usually dry land, as such due to the high runoff rate, there will be increased incidences of flooding.
