Question

As sea floor spreading occurs, the oceanic plate _______.

Answer 1

Becomes older

Explanation:

As sea floor spreading occurs at divergent margins, the oceanic plate becomes older. Younger plate margin are the closest to the margin whereas the older plates bushes backward away from the spreading centers.

• The idea that the sea floor spreads was postulated by Harry Hess shortly after the second world war around the 1960's.
• At divergent margins new crust materials from the mantle are brought to the surface.
• They crystallize and settle at the flanks of plate margins.
• Older ones are pushed backward away from the margin into far away subduction zones.
