slow moving plate tectonics
the oceanic plate
miners have been able to dig into the earths crust by big machines and other huge tools and they have only dig ed 2 miles into the earths crust
Other orbiting bodies contain more iron then earths crust does
Volcano
A volcano is the opening called in the earths crust called through which lava gases and other pieces of rock erupt.
majority of valcanoes follow the edges of the tectonic plates, which are the weaker parts of earths crust, therefore volcanoes form durin the crust giving away to the pressure built up. other volcaoes form other places due to weak parts of earths crust
other orbiting bodies contain more iron than earths crust does

Seismologist
it is the movement of the earths crust. it moves inwards towards other plates so the earths crust moves upwards therefore forming mountains, volcanoes etc
Pressure
it helps meteoroids and other harmful space elements to fall into the earths crust
