Question

why does a snake struggle to slither on a sheet of glass or any other smooth surface

Answer 1

Hello Friend...☺
Because of smooth surface, there is no friction so snake can not slither their easily, he has to struggle. Friction provides help to snakes in slithering if there is no friction then snake can not move forward instead but it can slither but can not change position. Even we can not walk or run without friction.

Hope this helps you friend...❤

Answer 2

Heya....

Here is your answer...

Snakes move using specialized scales on their ventral surfaces (undersides) called scutes. These scutes attach to musculature which allows them to flex out away from the snake's body, propelling the snake by catching on to the ground and other surfaces and providing friction against which the snake may push to move forward. Smooth surfaces have fewer or no irregularities on which these scutes may catch, and limit the effectiveness of the snake's efforts.
