How and why are lines like snakes formed on the desert sand?

Dear student.

Your question is not clear and appears to be incomplete. Please mention what do you mean by lines like snake. If you mean how do snake survive in desert, then follow the below answer.

Common snake found in deserts are: Rattlesnake, Boa snake, Sonoran Gopher Snake etc. Few snakes having lines or stripes in the body are: Red-bellied black, Marsh snake etc.

Snakes have the following adaptations to live in deserts:
1. Their body mechanisms have evolved in such a way that they need very little water to survive in desert area where water is mostly scarce. Also they do not need food on daily basis.
2. The body colour of many desert snakes mimics the colour of desert sand. Hence they are less visible to their predators.  

Regards.
