Answer 2

Explanation:

Friction is a dissipative force responsible for inhibiting the relative motion between two surfaces in contact.

Now, if friction disappears from Earth, it will be become a dangerous event because of the following reason:

Friction provides retarding force to moving object as a result of which they come to rest.

In absence of friction, the moving objects will tend to move for eternal time periods and will not come to rest.
