Wind at the surface is slower than the "winds aloft"
The biggest effect is within a few inches of the ground.
Friction between the ground and air molecules slows down the wind near the Earth's surface. This creates a drag force that causes the wind to move in a more horizontal direction. Friction also causes the wind to decrease in speed, resulting in a gradient of wind speed with height above the ground. This is known as the boundary layer and affects the behavior of winds near the surface.
Air in the upper atmosphere speeds up.

Yes. Double the weight and double the friction.
Wind at the surface is slower than the "winds aloft" The biggest effect is within a few inches of the ground.
The wind at the surface of the ground where the molecules are having friction is moving slower than the wind above the surface.
the rougher the surface is, the more friction there will be

friction
No, it doesn't, the only important thing is the force perpendicular to the surface (weight) and friction coefficient.

Yes. Double the weight and double the friction.
the smoother a surface is, the less friction it produces.
The rougher a surface is, the higher the coefficient of static and kinetic friction will be.

more rough surface more friction object have
