Students learn about seafloor spreading in class doing a paper strip model of divergent and convergent plate boundaries.
Seafloor spreading demonstration.
Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor.
Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them.
Spreading rates determine if the ridge is fast intermediate or slow.
This week i came up with an effective demonstration for modeling the process of seafloor spreading.
The rate at which new oceanic lithosphere is added to each tectonic plate on either side of a mid ocean ridge is the spreading half rate and is equal to half of the spreading rate.
Using four rectangular labs tables and two bed sheets i created a movable seafloor that can model a divergent boundary and a convergent boundary.
