Over time new.
Seafloor spreading model parts.
2 what prominent feature of the ocean floor is missing from the model at this point.
The oldest sections should be the sections on both sides furthest from the middle 4.
When the strips of paper are pulled out what process does this represent.
Students work as individuals.
1 what feature of the ocean floor does the center slit represent.
Spreading rates of are common along the mid atlantic and the mid indian ridges.
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.
Seafloor spreading occur along relatively narrow areas at the crest of oceanic ridges called.
Modeling sea floor spreading lab questions answer the following questions using your model of sea floor spreading.
Geologically are actually submerged parts of the continents.
Looking at parts of the model have students record their ideas on the student worksheet.
Seafloor spreading is the creation of new seafloor or new oceanic crust 5.
The base is best if made from poster board or card stock.
1 to 5 centimeters per year.
Subduction and sea floor spreading are processes that could alter the size and form of the ocean.
For instance the atlantic ocean is believed to be expanding because of its few trenches.
4 what does the space under the paper.
The best known ridge on the globe runs straight down the.
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.
3 what do the side slits 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.
A model of sea floor spreading teacher s guide ellen p.
The strips of paper represent oceanic crust or seafloor.
The earth does not get bigger.
A model of seafloor spreading key 1.
Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them.
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.
This process occurs along divergent plate boundaries at areas called mid ocean ridges.
The width and length of the base are not critical as long as they are.
Paper strip represents seafloor 2.
The center slit represents a mid ocean ridge 2.
What does the paper strip used in the model represent in real life.
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.
