BecAuse if it has a rough surface it will take longer to fo down and it will hurt you butt
the same reason you don't their legs are at the bottom The reason is that ... The frozen sea is very hard, bumpy and difficult to slide on so the penguins do not have the smooth easy surface you might imagine. Also the bumpy surface of the ice after a while will probably hurt their bellies. The reason is that ...

the surface of this floor is very smooth.
A very smooth surface or a smooth surface coated with a liquid, oil or a Teflon like substance.
It has to do with friction. The smooth paper allows the pen or pencil to slide while rougher paper doesn't.
Any very hard very smooth surface.
Not really, paint does not stick to polyethylene very well and would make the slide rough rather then 'slippery'.Alternative:Actually, some forms of epoxy paints will adhere to polyethylene. The issue is roughness again. If you prepare the surface by sanding it smooth, and spray the paint in layers, sanding each layer with progressively finer grit sandpaper, you should be able to produce a smooth enough finish to make sliding feasible. You might also need to wax or polish the slide's surface after the last coat of paint has set completely.If however there is any portion of the surface of the slide that is dirty, or has any sort of oil on it, the paint will not adhere there, and will create a peeling point that could spread over the entire surface of the slide.
Bumpy. It has a very rocky texture, so it wouldn't be very smooth. Venus is a bumpy planet.
because it is very smooth therefore it reflects the light
so the animal can slide out when it gets to big
That surface would be called a "mirror".
its a thig or somthing like a tabla surface
It is reflected at the same angle to the normal. The normal is a line perpendicular to the surface.
