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.

Friction ridges which form fingerprints begin to form?
The same time they form their fingers/hands in the womb
Why do moving objects on earth always experience friction while objects in outer space usually do not?
Friction is caused by the movement against anything, including the atmosphere, which grows thinner and thinner as you leave the planet. (It is also why planes fly so high in altitude - less friction means greater miles per gallon of jet fuel.) As an experiment, part your fingers such that there is air (or space) between them all; then run your wrist either side to side or forward and backward very rapidly so that you will feel the friction of the air against your fingers. This cannot happen in a vacuum of space, not that you could even attempt it.
Which processes form ridges and valleys?

How and why do fingerprints develop on the surface of objects and what is the most common form of latent fingerprint development A Glass Glossy Magazine Cover Painted Wood and Phone Receiver?
Impressions of fingerprints may be left behind on a surface by the natural secretions of sweat that is present in friction ridge skin, or they may be made by ink or other substances transferred from the peaks of friction ridges on the skin to a relatively smooth surface.
What are 5 types of friction?
1. Static2. Sliding3. Rolling4. Air5. Fluid
Which structures of the dermis give rise to friction edges or fingerprints?
Dermal ridges cause the overlying epidermis to form epidermal ridges. Collectively these ridges are called friction ridges.
