Worldwide, the mountains are the evidence of crustal plates.
There are 14 crustal plates on the earth.
Evidence such as the fitting of the continental coastlines, the distribution of similar fossils across different continents, and the alignment of mountain ranges across separate continents all suggest that crustal plates have moved over time. Additionally, the presence of mid-ocean ridges and magnetic striping on the seafloor provide further support for plate tectonics and the movement of crustal plates.
No, plates and crustal plates are the same thing. They refer to the large, rigid sections of the Earth's lithosphere that move around on the semi-fluid asthenosphere beneath them. These plates are made up of both oceanic and continental crust and are responsible for the movement of continents and the formation of geological features like mountains and earthquakes.

The crustal plates are in constant motion, there is no last movement

Yes, tectonic plates are also known as crustal plates.

by bubbling hot magma in the earth's inner core, erupting from volcanoes and causing earthquakes which cause the crustal plates to move.
The best evidence of crustal movement is seismic activity, where earthquakes occur due to the shifting of tectonic plates underneath the Earth's surface. Geological features like mountains, rift valleys, and ocean trenches also provide evidence of crustal movement over long periods of time. Additionally, the alignment of magnetic minerals in rocks recording the past movements of the Earth's magnetic poles is another indicator of crustal movement.
Molten magma from the mantle rises at the top oceanic ridge, cools and solidifies, continually forming a crustal plate. Hundreds to thousands of miles from the ridge the plate moves downward into the mantle at the contact with another plate and melts. The continuous process resembling a large "conveyor belt" moves the crustal plate a few centimeters each year.
