Convection under the Earth's surface occurs due to the heat generated by the radioactive decay of elements in the Earth's interior. This heat causes hotter materials to rise and cooler materials to sink, creating a circular motion of material within the Earth's mantle. This convection helps drive the movement of tectonic plates and contributes to processes like seafloor spreading and subduction.
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
You're thinking of magma.
Yes it is call a crust 😁
fre
That there are hot spots concisting of gas under the earths surface.
they just happen earthquakes are caused from the plates under earths surface moving

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.

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.
