• passive

A foreland basin can form from what process?

• "Loading" the crust with a thick mountain belt due to thrust faulting.

• Subduction at a trench keeps the crust low which fills with sediment from a nearby volcanic arc.

• Tensional forces caused by rising mantle material behind a volcanic arc over a subducted slab combined with with oceanic trench rollback
