The surface of the brain is not regarded as being smooth. In a normal human brain, there are definite "folds" evident, and we often use the term convoluted to describe the outward appearance of the brain. Use the link below to see some images that will help lock in the idea.
calcite has a regular arrangement of atoms.
a conchoidial fracture is a "shell-like" fracture with a smooth curved surface
The facing operation is the part of machining where the final surface is given it's finishing touches. Usually this is done by fine turning of the surface to produce a highly polished and smooth surface.
Wear on the rock, like for example in a river there are a lot of smooth pebbles because the water flowing by smooths the surface
Sound is mechanical energy. The energy displayed by the source is transferred into the medium through which it travels. When the wave, that moving energy, comes into contact with a surface, some of the energy is transferred into the surface. But how much? The more solid and "less moving" the surface (seen on a tiny scale), the less the moving air waves, those compression and rarifaction waves, can transfer energy into the surface. And that's what it's all about. The "softer" the surface, the more those pressure waves in air can affect that surface and transfer their energy into it.
No it is made up of folded brain matter
Any surface which is wrinkled has a larger surface area than the space it actually takes up.
its a thig or somthing like a tabla surface
smooth surface.
on a smooth surface
jagged
Smooth surface
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.
The surface of electric machine are smooth why
It is not smooth it has craters
