What does the center slit of your model represent?
The center slit represents a Mid-Ocean Ridge 2. The strips of paper represent oceanic crust or seafloor. Seafloor spreading is the creation of new seafloor or new oceanic crust 5. The earth does not get bigger.
Why was it important that your model have identical patterns of stripes on both sides of the center slit?
Why is it important that your model have an identical pattern of strips on both sides of the center slit? The model has identical strips because, as the magma rises at the mid ocean ridge ½ goes to the right and ½ goes to the left of the mid ocean ridge. Each one of these strips represents Earth’s magnetic history.
What feature of the ocean floor does the slit stand for what prominent feature of the ocean missing from the model at this point?
Mid-Ocean Ridge
What feature is generated along spreading centers?
Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest.
What occurs at spreading centers?
Spreading centers occur where two plates are moving away from each other, and deep cracks are opened through the crust. This lengthening of the crust allows magma from the upper mantle to rise to the surface and cool, commonly forming basalt.
Where are spreading centers found?
Spreading centres are found at the crests of oceanic ridges. The age of Earth’s oceanic crust can be presented to show the pattern of seafloor spreading at the global scale.
What is another name for tectonic spreading centers?
Plate tectonics, continental drift, spreading centers, subduction zones.
