Why Plate Tectonics Continues: The Driving Forces
Plate tectonics is slow convection of thee Earth 's mantle. Hot, less dense material rises frem te core-mantle boundary, spreads benefiath thee lithosplee, and cool before sinking again. This convectiva flow exerits drag oin thee overlying plates, pulling them apart aid mid- oceain ridges and pushing them tother at subduction zone.

I n addition to mantle convection, thee cololing and contraction of thee planet also contribute. The Earth 's internal nal heat budget is slowly declining, but over the next few hundred million years, thee loss is too small to stall plate movement.

Thee Closing of thee Atlantic ande thee Mediterranean

Perhaps thee most dramatic prestion is then eventual assembly of a new supercontingent.

Of special interest is the Yellowstone hotspot, currently benefiath the North American Plate.
