Want this question answered?
Rubbing the surfaces of two objects together is friction. This requires forces parallel to the surfaces and usually accompanied by wear and a rise in temperature.
Two surfaces touching together creates friction. rub your hands together(two surface from your each hand) creates friction and head is the result.
The 2 factors on which friction two body is depended uponThe mass of the body,the coefficient of Static or limiting or dynamic friction( as the case may be)Gravity too.
Rough surfaces do create more friction than smooth surfaces. How much friction is created depends on how rough the surface is.
Both. Suppose you want to move something over the ground. If it becomes heavier then it will be subject to more friction on account of gravity. If it's lower surface becomes rougher then again, it will be subject to more friction. The force pressing two surfaces together and the roughness of the two surfaces act together to produce friction.

two rough surfaces :)

What happens when you rub sandpaper back and forth over a piece of wood? The strength of the friction force depends upon the types of surfaces involved and how hard the surfaces push together.

Surface temperature, Weight of the object, Roughness of surface and the object

Rough surfaces, the rougher the surface, the greater the friction.
Because friction is less on smooth surfaces. Smoother the surfaces, lesser the friction.
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.
