Picture Of A Sea Floor Spreading Model Activity Cut Out

In this experiment you ll make a seafloor spreading model to learn more about how plate tectonics work and create mid ocean ridges.

Picture of a sea floor spreading model activity cut out.

This model represents the flow of lava over time due to plate tectonics at mid oceanic ridges seafloor spreading. Seafloor spreading explore 1 subduction in trenches 1. Print cut out and glue together a three dimensional paper model that illustrates sea floor spreading and subduction. Place a piece of white paper on the cardboard and cut the paper so that flaps of paper can be pulled down.

Please refer to the picture as you build this model. To create a working model of sea floor spreading follow the model seen below figure 1. Have students work in groups of four. Continue pulling the magma strips until the magma sticks slide across the ocean floor and drop off into the trenches.

The purpose of this activity is to make a simple model that shows the evolution of oceanic crust through sea floor spreading. Cut slits in the cardboard each about 2 mm wide as shown eg. Cut out a piece of stiff cardboard eg. The 4 tactile surfaces will represent rock of various ages depending on how long ago it was laid down.

The width and length of the base are not critical as long as they are at least 12 cm wide and 30 cm long. Today we are going to create a model that i hope will incorporate all of your important points 1. During sea floor spreading two tectonic plates move apart forming a crack in the ocean floor. Have students pick up materials needed for the activity.

Modeling sea floor spreading reviewing content mid ocean ridges are long underwater mountain chains that rise up from the ocean floors. Students will make their own models of seafloor spreading and the magnetic strips that occur in the seafloor. Cut 3 slits each slightly more than 8 cm wide. 25 x 35 cm.

Plate tectonics tennis ball globe model activity print and color a two dimensional world globe showing plate boundaries then cut it out and. Model of seafloor spreading templates one with three straight lines and another with striped bands or striped bands with arrows colored pencils or crayons. New ocean crust is continually added to earth along these ridges in a process called sea floor spreading. Students work with a.

Students work as individuals. Simple diagrams and easy to understand explanations of the processes are included. And deposition sorting is an activity that helps students understand the differences between these three concepts by having them sort examples into categories. As the ocean crust moves under the continental crust it creates a trench.

The base is best if made from poster board or card stock. A model of seafloor spreading purpose. As magma flows out of the ridge the newly formed crust pushes older crust away from the ridge. You can make your own model of a spreading oceanic ridge offset by transform faults as follows.

Over time new. 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.
