Slide 20 - Quiz

When there is deforestation..
A
there is less interception and so the soil becomes saturated more quickly, this leads to surface runoff and the water will reach the river more quickly
B
more interception will happen, soil will have chance to infiltrate in the soil and flow to the river underground
C
there are more impermeable surfaces so no interception and more surface runoff and water reaches the river more quickly
D
the soil can be eroded and washed into the river which can decrease the amount of water that can be held in the river, meaning it will be more likely to flood
