Detailed Solution

The above statement is true.
The friction between the two surfaces in contact with each other is because of the contact irregularities of the two surfaces. A force that hinders the movement of an object along the path is static friction. For example, this friction occurs when two fabrics slide over each other. Static friction can be seen when we walk on roads; for instance, our feet are in touch with the floor, or when we push heavy objects, the force we are applying to push the heavy object is less than the force that resists the movement of the body, which results in static friction.
Static friction is caused by adhesion and light chemical attraction between two surfaces. And friction, in general, is caused by imperfections in every surface gripping together and overlapping.
