The formation of igneous rock from magma
For example the formation of volcanoes or island arcs at convergent plate boundaries. Or mid-ocean ridges and therefore ocean-floor spreading at divergent plate boundaries.

Magmatism is the process by which magma is formed and moves within the Earth's crust. It involves the movement of molten rock beneath the surface, which can eventually lead to volcanic eruptions or the formation of igneous rocks upon cooling and solidification. Magmatism plays a crucial role in shaping the Earth's geology and is responsible for the creation of new crust in tectonic plate boundaries.

What are the sources of internal heat?
Main sources of internal heat are Magmatism and Radioactivity.
How does a sedimentary rock turn into a metamorphic rock then into an igneous rock?
First, through metamorphism, then by melting and magmatism.

Chalcophile elements occur in crust mantle core or core atmosphere?
Chalcophiles combine readilly with sulphur which is predominantly lithophile so chalcophiles are enriched in the mantle and crust, particulary associated with magmatism.

magmatism.

Why is there so much copper in Arizona?
The initial source for copper in Arizona were igneous intrusions into native host rock. The copper veins were eventually exposed through erosion at the surface. Copper then leached back into the ground and recrystallized in the form of copper minerals in what is called a supergene enrichment zone. The igneous intrusions were due to a long period of magmatism from the middle of the Mesozoic to the early Cenozoic era.
