Sea Floor Spreading Model Cut Out

The strips of paper represent oceanic crust or seafloor.

Sea floor spreading model cut out.

25 x 35 cm. Create a model of the spreading sea floor. The width and length of the base are not critical as long as they are at least 12 cm wide and 30 cm long. Cut out a piece of stiff cardboard eg.

Please refer to the picture as you build this model. Cut slits in the cardboard each about 2 mm wide as shown eg. Use the model to show them the creation of new sea floor at spreading centers and the disappearance of old sea floor at subduction zones. The base is best if made from poster board or card stock.

If you were making a model of sea floor spreading what are the important ideas that are associated with seafloor spreading. You may wish to cut the paper model pieces for the students ahead of time or use a model you have made as a demonstration for the class. 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 oldest sections should be the sections on both sides furthest from the middle 4.

Take a cardboard cylinder shaped container such as a quaker oats container and cut a vertical slit about 3 inches long and inch wide down the side. Think pair share turn and talk to your elbow partner. This model represents the flow of lava over time due to plate tectonics at mid oceanic ridges seafloor spreading. White 8 x 11 in.

Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. The earth does not get bigger. You can make your own model of a spreading oceanic ridge offset by transform faults as follows. The 4 tactile surfaces will represent rock of various ages depending on how long ago it was laid down.

A model of seafloor spreading key 1. For instance the atlantic ocean is believed to be expanding because of its few trenches. 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. 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.

Seafloor spreading is the creation of new seafloor or new oceanic crust 5. Cut 3 slits each slightly more than 8 cm wide. To create a working model of sea floor spreading follow the model seen below figure 1. 3 slits as shown here.

Cut out the labels approximately 1 tall by 1 2 wide. The center slit represents a mid ocean ridge 2. Subduction and sea floor spreading are processes that could alter the size and form of the ocean.
