Description
This data table provides spreading rates for divergent boundaries (spreading centers) in the Pacific, Atlantic, and Indian oceans. The rates differ between the 3 spreading centers and along their respective boundaries. Slower spreading rates lead to a rough topography because the tectonic plate is allowed to cool before moving away from the ridge. Slow spreading rates also form deep central rift valleys. Faster spreading rates lead to a smoother oceanic surface because the tectonic plate is warmer and has less deformation. |
|
Instructions Compare the spreading rates at the different spreading regions and determine which is spreading the fastest. |
