coefficient of friction
This is called texture for Apex
cleavage, if a natural property of the mineral (e.g. mica); or a fault, such as in a gemstone.
This property is called cleavage.
All materials have a property called the coeffecient of kinetic friction. When this property is high, a higher friction force resists the motion of objects across the surface. Sandpaper has a higher coefficient of kinetic friction as compared to something like ice. This is because ice is smooth whereas the surface of sandpaper is very rough which increases the friction it causes.
It's actually texture APEX
A snake can move on a smooth surface. However, just like most other animals, it does require friction to exist between the surface and its body to move efficiently. A human would have difficulty walking on ice!
Smooth Texture

"Surface characteristics" merely describe the way a surface of a how the surface of a painting or sculpture looks or actually feels--rough, smooth, etc.

Smooth surface
The only reason a material is able to reflect light is because of its smooth surface and the substance that it is made of which are physical property
No it does not have to be smooth.
The leaves of Betula populifolia are smooth on the lower surface.
The rough surface is better than the smooth surface for the frictional force to act.
