This idea played a pivotal role in the development of the theory of plate tectonics which revolutionized geologic thought during the last quarter of the 20th century.
Seafloor spreading demonstration.
Spreading rates determine if the ridge is fast intermediate or slow.
Spreading rate is the rate at which an ocean basin widens due to seafloor spreading.
Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them.
Students learn about seafloor spreading in class doing a paper strip model of divergent and convergent plate boundaries.
This week i came up with an effective demonstration for modeling the process of seafloor spreading.
Using four rectangular labs tables and two bed sheets i created a movable seafloor that can model a divergent boundary and a convergent boundary.
