- Metamorphism
- Magmatism
- Isostasy (epirogenic movements)
- Orogenesis (orogenic movements)
Magmatism and Plate Tectonics
Rock melting can be produced by the following processes:
- A raise in the rock temperature
- A drop in the confining pressure

Compressed Air Distribution, Treatment, and Hydraulic Systems
Distribution Network
The distribution network is the set of pipes that leads compressed air to all the elements of the pneumatic circuit. This network starts from the deposit and guarantees the pressure and air velocity at all points. The pipes of the distribution network must have a diameter that ensures compliance with these conditions. The diameter of the pipe is a function of:
- Velocity of air circulation
- Pressure loss
- Working pressure
- Length of conduction
- Existing bottlenecks along the conduction
