Sea Floor Spreading 3d Model

Operation of the model. 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. The center slit represents a mid ocean ridge 2.

Sea floor spreading 3d model.

The earth does not get bigger. The mid ocean ridge is the region where new oceanic crust is created. Students work as individuals. A model of seafloor spreading key 1.

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. The strips of paper represent oceanic crust or seafloor. One intriguing thing about the rock that comes from seafloor spreading is that it shows the history of the earth. Over time new.

South becomes north and north becomes south. The rocks on the seafloor show the history of the magnetic changes in the earth. The process of sea floor spreading. Seafloor spreading theory that oceanic crust forms along submarine mountain zones known collectively as the mid ocean ridge system and spreads out laterally away from them.

Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. 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. Teaching kids about divergent boundaries. The oceanic crust is composed of rocks that move away from the ridge as new crust is being formed.

The oldest sections should be the sections on both sides furthest from the middle 4. The formation of the new crust is due to the rising of the molten material magma from the mantle by convection current. Seafloor spreading this activity is included in the deped learner s module for grade 10 it teaches students the concept of seafloor spreading. 3d seafloor models for download files in 3ds max c4d maya blend obj fbx with low poly animated rigged game and vr options.

Seafloor spreading is the creation of new seafloor or new oceanic crust 5. Slide the sea floor into the three slits in the shoebox and pull it down from underneath so that the numbers 4 are just visible. By using board papers bond papers and coloring materials they are able to make a 3d model of seafloor spreading. This is the position the sea floor would have had 4 million years ago.

For example every million years the earth s magnetic poles tend to reverse 4 or 5 times. Slide the sea floor into the trench as well.
