abrasive means to smooth out a rough surface
smooth surface.
the rough surface creates more friction as to that of soft surfaced ones
as we know that suction pump stick on a smooth non-porous surface but rough surface contains pores due to which suction pump is not able to maintain grip with the rough surface.
Rough surfaces do create more friction than smooth surfaces. How much friction is created depends on how rough the surface is.
The rough endoplasmic reticulum has ribosomes on its surface. This is what make is "rough"
Smooth surface
A bumpy, rough surface so you don't slip.
Its surface is rough because of all the rock's and crater's in its surface.
True, but only to a point. If the surface is too rough debris can get lodged between the wheels causing them to lock up. Which generally will lead to your face meeting the previously mentioned rough surface. However if the surface is not rough enough then it is difficult for the wheels to get a grip on the surface. Which usually will also lead to a meeting between the very smooth surface and your face.
The rough surface is better than the smooth surface for the frictional force to act.
The Rough Endoplasmic Reticulum (Rough ER) has ribosomes on its surface.

The moon's surface is rough - due to numerous impacts from meteorites
when light hits a rough surface it scattters.
no zinc is not rough it's surface is smooth
Reflection of light from a rough surface is known as "Diffused" or "Irregular" reflection, because the light rays are barely seen after the reflection of light from a rough surface.
