Sea Floor Spreading 3d Model

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.

Sea floor spreading 3d model.

A model of sea floor spreading teacher s guide ellen p. Seafloor spreading is the creation of new seafloor or new oceanic crust 5. One intriguing thing about the rock that comes from seafloor spreading is that it shows the history of the earth. Teaching kids about divergent boundaries.

Slide the sea floor into the trench as well. 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. For example every million years the earth s magnetic poles tend to reverse 4 or 5 times. By using board papers bond papers and coloring materials they are able to make a 3d model of seafloor spreading.

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

3d seafloor models for download files in 3ds max c4d maya blend obj fbx with low poly animated rigged game and vr options. 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. Seafloor spreading this activity is included in the deped learner s module for grade 10 it teaches students the concept of seafloor spreading. The rocks on the seafloor show the history of the magnetic changes in the earth.

The process of sea floor spreading. Students work as individuals. The formation of the new crust is due to the rising of the molten material magma from the mantle by convection current. South becomes north and north becomes south.

The oldest sections should be the sections on both sides furthest from the middle 4. This is the position the sea floor would have had 4 million years ago. 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. The strips of paper represent oceanic crust or seafloor.

Over time new. A model of seafloor spreading key 1.
