Dermal ridges cause the overlying epidermis to form epidermal ridges. Collectively these ridges are called friction ridges.
Polishing the surface or coating it with a lubricant is a way of reducing friction. To increase friction just hammer some ridges on the surface.
All surfaces that come into contact with each other generate friction. The magnitude of the friction depends on the specific properties the two surfaces. General rule: smooth surface --> less friction. But this fails sometimes too.
Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.
Lubricants reduce friction by replacing sliding friction with fluid friction.

Your fingers have friction ridges so that we can grab or catch or even hold things with our fingers. If we did not have these friction ridges then probably we wouldn't be able to hold things without the help of our fingers.

Mountains look like little ridges or bumps on a map and you can also check the key for more help.
