Picture Of A Sea Floor Spreading Model Activity Cut Out

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.

Picture of a sea floor spreading model activity cut out.

And deposition sorting is an activity that helps students understand the differences between these three concepts by having them sort examples into categories. Please refer to the picture as you build this model. Print cut out and glue together a three dimensional paper model that illustrates sea floor spreading and subduction. Today we are going to create a model that i hope will incorporate all of your important points 1.

In this experiment you ll make a seafloor spreading model to learn more about how plate tectonics work and create mid ocean ridges. Have students work in groups of four. Plate tectonics tennis ball globe model activity print and color a two dimensional world globe showing plate boundaries then cut it out and. As magma flows out of the ridge the newly formed crust pushes older crust away from the ridge.

The base is best if made from poster board or card stock. Model of seafloor spreading templates one with three straight lines and another with striped bands or striped bands with arrows colored pencils or crayons. You can make your own model of a spreading oceanic ridge offset by transform faults as follows. Seafloor spreading explore 1 subduction in trenches 1.

Cut slits in the cardboard each about 2 mm wide as shown eg. The width and length of the base are not critical as long as they are at least 12 cm wide and 30 cm long. Place a piece of white paper on the cardboard and cut the paper so that flaps of paper can be pulled down. A model of seafloor spreading purpose.

This model represents the flow of lava over time due to plate tectonics at mid oceanic ridges seafloor spreading. Cut out the labels approximately 1 tall by 1 2 wide. Cut 3 slits each slightly more than 8 cm wide. Modeling sea floor spreading reviewing content mid ocean ridges are long underwater mountain chains that rise up from the ocean floors.

25 x 35 cm. To create a working model of sea floor spreading follow the model seen below figure 1. The purpose of this activity is to make a simple model that shows the evolution of oceanic crust through sea floor spreading. Have students pick up materials needed for the activity.

As the ocean crust moves under the continental crust it creates a trench. Students work as individuals. During sea floor spreading two tectonic plates move apart forming a crack in the ocean floor. The 4 tactile surfaces will represent rock of various ages depending on how long ago it was laid down.

New ocean crust is continually added to earth along these ridges in a process called sea floor spreading. A model of sea floor spreading teacher s guide ellen p. Students work with a. Students will make their own models of seafloor spreading and the magnetic strips that occur in the seafloor.

Continue pulling the magma strips until the magma sticks slide across the ocean floor and drop off into the trenches. Cut out a piece of stiff cardboard eg.
