anticline
Upward geological fold
An anticline is a fold in rock layers that arches upward, forming a ridge or dome shape with the oldest rocks at the center.
The term comes from geology, where it describes formations created by tectonic compression.
Anticlines often trap oil and gas beneath their arched strata, making them important in petroleum exploration.
The opposite formation, curving downward, is a syncline.
