Sea floor spreading equation.
Use the above equation to calculate spreading rate.
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.
The use of the equation relating ocean floor depth to sea floor spreading rate and distance from spreading center provides a geoscience context.
In 1912 when alfred wegener proposed that the continents had once been joined together and had split apart the biggest weakness in his hypothesis was the.
Activity ii see teaching notes and tips below is a follow up activity that has students use excel to graphically compare the model predictions to observations from several north atlantic cross sections.
Ranges of spreading throughout the world s oceans.
The use of the equation relating ocean floor depth to sea floor spreading rate and distance from spreading center provides a geoscience context.
Spreading rate is the rate at which an ocean basin widens due to seafloor spreading.
1cm yr to 10 cm yr.
Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor.
