Explanation:

----------------------------------------------------------------------

To,explain this first you should know what is Friction,

Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

A moving stone on a frozen lake surface keeps moving for a long distance because the friction is minimum on a smooth surface(However it is not 0).

But a moving stone on the grass land stops very soon because

Rougher surfaces have more friction between them. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.
