Cut the center of the clay strips and insert a cardboard on the part of the clay that was cut. 3. Push both ends of the clay strips. Observed what is formed. 4. Repeat step one in the other two pieces of modeling clay. 5. Slowly pull both ends of the clay strips. Observe what is happened to the clay strips. What have you found out? 1 .
What happened to the layers of the clay after they were pushed at both ends? NAS. The layers of the clay risen. 2. What type of plate boundary is showed when both ends are pushed? NAS. Convergent boundary 3. What happened to the layers of the clay after they were pull at both ends? NAS. The layers of the clay move away from the cardboard. 4. What type of plate boundary is showed when both ends are pulled? NAS. Divergent boundary Conclusion: Tectonic plate moves in a pattern called a convection cell that forms when arm material rises, cools, and eventually sink down.
