Floods affect the environment by destroying building, creating areas of more fertile soil and speeding up the weathering of rock.

Option A,B & C

Explanation:

Floods obviously destroy every building on its way ruining the whole place taking away the lives of people and stock. But the flood also carries many nutrients along it’s way which creates areas of more fertile soil.

Unexpected floods enter into the holes of the rock and during winter it transforms into ice and causes crack in the rock. The flood water gushing fast normally breaks down the corners of the rock hence causing weathering of rock.
