slickensides are polished surfaces of rock which are a rasult of rock moving against rock along a fault
There are four main properties of friction. These include it being an electrostatic force between two surfaces, it acts parallel to the surfaces that are moving against each other, it is independent of the area of the surfaces in contact with one another, and it never initiates motion - it only responds to it.
Yes , X-rays consist of first moving electrons ,because high voltage between cathode and anode causes the electrons to accelerate toward the anode,When the electrons strike the anode's target area, X-rays are emitted.
It is on smooth surfaces because the amount of friction is less.
By using cushioning packing material.
Lubricants reduce friction by various means. Here are some:They form a layer between surfaces that are moving with respect to each other that keeps those surface from contacting each other. The lubricant keeps the surfaces apart.The lubricant washes away particles that might cause friction between the surfaces. It acts as as cleanser.Some lubricants harden the surfaces of the parts they are lubricating to make them less subject to wear.

sliding friction
Different texture
slickenslides
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.

Moving cell contents to the left, right, or center of a cell.
rough surfaces because it has more bumps that stop it from moving faster
