1.What happened to the layers of the clay after they were pushed at both ends? ANS. The layers of the clay risen.
2.What type of plate boundary is showed when both ends are pushed? ANS.Convergent boundary
3. What happened to the layers of the clay after they were pull at both ends? ANS.The layers of the clay move away from the cardboard.
