What makes studying the beginnings of plate tectonics difficult?

it’s hard because rocks that are older are hard to find. And in order for scientists to be able to study the beginnings of the plate tectonics they need physical proof. Also the problem is that the oldest pieces of rocks have been subducted so the proof is long gone

Explanation:

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.
