Fold Mountains are formed from the collision of continental tectonic plates. Since neither plate sub ducts under the other, the colliding plates wrinkle and fold like a rug being pushed into a wall. What is the difference between a compass heading and a compass bearing?

Heading indicates the direction the ship/aircraft/vehicle you are in is moving.

Bearing is normally used to indicate the direction something else is relative to you.

The ship was heading 085 and maintaining a station on the carrier at two miles and a bearing of 200 from the carrier.

This is often the case where a ship or airplane is "pointed" on a bearing across the wind or current and "moving" on a heading that is the natural consequence of the combined forces on the hull.
