when two objects slide over each other, there is friction between them, the more friction, the harder it is to move one of the objects over the other.
Sliding kinetic friction is when two moving (kinetic) objects rub (slide) against each other, creating friction. Sliding friction creates heat, unlike rolling or fluid friction.
If you mean sliding friction, it's the friction generated by two objects sliding past one another. (Like when you rub your hands together when they get cold--the friction generates heat.) Sliding friction is also the main force which slows down a ball rolling on the ground; the two objects sliding past each other are the ground and the ball, and that creates friction.
Sliding friction prevents surfaces in contact from sliding past each other.
Transform boundary is when the plates are sliding past each other: ↑ ↓; Divergent is when plates are sliding away from each other: ← →; and convergent is when plates are sliding towards each other: → ←. Those are the three main plate boundaries.

Static friction is the friction between two objects that are not moving relative to each other (eg: a desk on the floor not moving), kinetic friction is the friction between two objects that are moving relative to each other (eg: a desk sliding on the floor)
Rolling friction is when an object that is rolling/sliding/moving on a surface is slowed down or stopped, because of the friction of the two objects rubbing against each other.
FRICTION .......... friction
Friction.
The force that slows down moving objects is friction, the action of two objects rubbing against each other. This scenario illustrates the action of Newton's Second Law.
