Slab Pull: The Primary Enginee of Plate Motion

Among thee tectonic driving forces, slab pull is widely regardezed as te most powerful, acquiting for approximately 80- 90% of thee total force that propels plate motion. The mechanism is prospecforward: as dense, cold oceanic lithosphere descends into the mantle at subduction zons, it pulls the connectted plate along with it. The steeper and faster the slab descends, the strorthe slab l pulforce becomes, accessiating plate plate movement.

These combined forces enable the Pacific Plate to reach velocities up to 11 centimeters per yes, making the fastest- moving major tectonic plate on Earth.

How Plate Speeds Change Over Time

Plate velocities are dynamic and vary signitantly across geological timescleles.

Hotspots are relatively stationary plumes of hot mantle material that serve a s valuable reference point for reconstructing plate motions over millions of years. The Hawaiiian- Emperor seamount chain, formed as thee Pacific Plate mover thee Hawaiian hotspot, exhibits a sharp bend around 47 million years ago.
