Want this question answered?
The amount of friction depends on the force pushing the surfaces together.
Friction does depend on the types of surfaces involved and how hard the surfaces push together. Friction would be very minimal if the surfaces were smooth and not pushing together too hard.
Force pushing two surfaces together
The frictional force is proportional to the "normal force"; that is, the force pushing the surfaces together, whether that is gravity or anything else.
How rough it is and how heavy it is.

the larger the force pushing the two surfaces together the stronger the microwelds will be , because more of the surface bumps will come into contact , to move one surface over an other , a force must be applied to break the microwelds .
one way is to make the surface rougher and another way is to increase the force pushing the surfaces together.
Surface temperature, Weight of the object, Roughness of surface and the object
it is usually greater than static friction
the larger the force pushing the two surfaces together the stronger the microwelds will be , because more of the surface bumps will come into contact , to move one surface over an other , a force must be applied to break the microwelds .
We see tectonic plates pushing together in what is called a convergent plate boundary.
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.
