Paper strip represents seafloor 2.
Seafloor spreading model parts.
Seafloor spreading occur along relatively narrow areas at the crest of oceanic ridges called.
Seafloor spreading is the creation of new seafloor or new oceanic crust 5.
Subduction and sea floor spreading are processes that could alter the size and form of the ocean.
3 what do the side slits represent.
1 to 5 centimeters per year.
The mid atlantic ridge for instance separates the north american plate from the eurasian plate and the south american plate from the african plate the east pacific rise is a mid ocean ridge that runs through the eastern pacific ocean and separates the pacific plate from the north american.
Pulling out the strips of paper represents the process of seafloor spreading 3.
To create a working model of sea floor spreading follow the model seen below figure 1.
Due to this continuous seafloor spreading occurs and makes atlantic ocean floor to be connected to other continental crust making the ocean gets wider over the time.
The base is best if made from poster board or card stock.
Also creating a model for sea floor spreading will allow you to see a hands on example of this phenomenon.
Looking at parts of the model have students record their ideas on the student worksheet.
Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them.
4 what does the space under the paper.
The width and length of the base are not critical as long as they are.
Spreading rates of are common along the mid atlantic and the mid indian ridges.
Students work as individuals.
What does the paper strip used in the model represent in real life.
The best known ridge on the globe runs straight down the.
When the strips of paper are pulled out what process does this represent.
Seafloor spreading is the process of molten material from the mantle being pushed upward to the surface of the earth and spreading apart creating new earth.
The oldest sections should be the sections on both sides furthest from the middle 4.
A model of sea floor spreading teacher s guide ellen p.
2 what prominent feature of the ocean floor is missing from the model at this point.
The center slit represents a mid ocean ridge 2.
Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor.
Geologically are actually submerged parts of the continents.
The earth does not get bigger.
Students will make a paper model illustrating the concept of sea floor spreading and the development of symmetrical magnetic stripes on either side of a mid ocean spreading center.
1 what feature of the ocean floor does the center slit represent.
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.
A model of seafloor spreading key 1.
Modeling sea floor spreading lab questions answer the following questions using your model of sea floor spreading.
Over time new.
