There are lot of different things that can slide each other for example in science we learn about the plate boundaries and one of them is transform boundaries that grind or slides each other.
transform boundary
Earthquakes
Tectonic Plates move by trying to push past each other and by trying to slide past each other.
Particles in a liquid can slide past each other but are still packed together.
It where to plates rub past each other; push against each other; or move away from each other.
earthquake
its called a transform boundary
A transformed plate margin is the plate that slides past each other
When two plates slide past each other, this is called a transform fault. Earthquakes can occur when the plates scrape by. If the earthquake happens underwater, a tsunami may occur. (Like in Japan)
transform boundary
gliding
They slide past each other
The best way to store microscope slides is in a slide box. A slide box will keep slides from sticking to each other, keeping them intact.
It is where one plate slides past another plate, rubbing against it. One slides right, the other left. An example would be North America. Your Welcome.
Theny happen in Mountain ranges when slides hit each other.
Molecules in a liquid can move past each other, if that's what you were trying to ask; I'm not sure what "separate past each other" is supposed to mean.
The San Andreas fault lies along a transform fault line where two of the Earth's plates are sliding past each other. At San Andreas, the Pacific Plate (to the west) slides past the North American Plate (to the east).
