You're thinking of magma.
Yes it is call a crust 😁

the moving of the plates under the earths surface
pressure from the heat under the earths surface
There is no ladder if (of?) rocks under the earths surface, your question is meaningless.
An intrusion.
the tectonic plates are shifting under the earths surface.
Continental drift occurs under the earths crust by convection currents in the mantle which drives the plates. It has been happening since the development of the earths core and is happening now and until the end of the earth.

Lava
An earthquake is started when two plates (which lie under the Earths surface) rub together this creates movement which then sometimes pulls/pushes at the earths surface and creates giant cracks in the earths surface... and that is how an earthquake is started.
