Friction between sliding surfaces is caused by _____. inertia microwelds the normal force gravity

OpenStudy (worlddomination):

both gravity and weight are correct answers. Although I'd say gravity is "more correct" because some books define weight to be the force required to hold an object in place, which is opposite and not necessarily equal to gravity. No one will ever argue against gravity being the attractive force between you and the earth.
