Please refer to the picture as you build this model.
Picture of a sea floor spreading model activity cut out.
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.
Cut out the labels approximately 1 tall by 1 2 wide.
Plate tectonics tennis ball globe model activity print and color a two dimensional world globe showing plate boundaries then cut it out and.
In this experiment you ll make a seafloor spreading model to learn more about how plate tectonics work and create mid ocean ridges.
The width and length of the base are not critical as long as they are at least 12 cm wide and 30 cm long.
25 x 35 cm.
Modeling sea floor spreading reviewing content mid ocean ridges are long underwater mountain chains that rise up from the ocean floors.
Have students pick up materials needed for the activity.
Students work with a.
Seafloor spreading explore 1 subduction in trenches 1.
Simple diagrams and easy to understand explanations of the processes are included.
Have students work in groups of four.
A model of seafloor spreading purpose.
Continue pulling the magma strips until the magma sticks slide across the ocean floor and drop off into the trenches.
Today we are going to create a model that i hope will incorporate all of your important points 1.
A model of sea floor spreading teacher s guide ellen p.
To create a working model of sea floor spreading follow the model seen below figure 1.
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.
And deposition sorting is an activity that helps students understand the differences between these three concepts by having them sort examples into categories.
Model of seafloor spreading templates one with three straight lines and another with striped bands or striped bands with arrows colored pencils or crayons.
Place a piece of white paper on the cardboard and cut the paper so that flaps of paper can be pulled down.
As magma flows out of the ridge the newly formed crust pushes older crust away from the ridge.
Cut 3 slits each slightly more than 8 cm wide.
Students work as individuals.
This model represents the flow of lava over time due to plate tectonics at mid oceanic ridges seafloor spreading.
New ocean crust is continually added to earth along these ridges in a process called sea floor spreading.
As the ocean crust moves under the continental crust it creates a trench.
3 slits as shown here.
Cut slits in the cardboard each about 2 mm wide as shown eg.
The purpose of this activity is to make a simple model that shows the evolution of oceanic crust through sea floor spreading.
Cut out a piece of stiff cardboard eg.
During sea floor spreading two tectonic plates move apart forming a crack in the ocean floor.
Students will make their own models of seafloor spreading and the magnetic strips that occur in the seafloor.
