Answer 2

here's your answer......dear friend.....

we are able to walk on a rough surface as compared to smooth surface because of friction.........

because friction exerts a backward force on the surface so it is easy to walk .......

rough surface has pores on it......these pores rub against the frictional force acting on it........
