Sea Floor Spreading 3d Model

Over time new.

Sea floor spreading 3d model. 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. The center slit represents a mid ocean ridge 2. 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. Seafloor spreading this activity is included in the deped learner s module for grade 10 it teaches students the concept of seafloor spreading.

Students work as individuals. The process of sea floor spreading. The rocks on the seafloor show the history of the magnetic changes in the earth. 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.

For example every million years the earth s magnetic poles tend to reverse 4 or 5 times. A model of sea floor spreading teacher s guide ellen p. The oldest sections should be the sections on both sides furthest from the middle 4. One intriguing thing about the rock that comes from seafloor spreading is that it shows the history of the earth.

This is the position the sea floor would have had 4 million years ago. 3d seafloor models for download files in 3ds max c4d maya blend obj fbx with low poly animated rigged game and vr options. South becomes north and north becomes south. Seafloor spreading is the creation of new seafloor or new oceanic crust 5.

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. A model of seafloor spreading key 1. The strips of paper represent oceanic crust or seafloor. The oceanic crust is composed of rocks that move away from the ridge as new crust is being formed.

Slide the sea floor into the trench as well. By using board papers bond papers and coloring materials they are able to make a 3d model of seafloor spreading. The formation of the new crust is due to the rising of the molten material magma from the mantle by convection current. Teaching kids about divergent boundaries.

The mid ocean ridge is the region where new oceanic crust is created. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor.
