The Earth's crust is not a solid shell. It is made of thick, interconnecting pieces called tectonic plates that fit together like a puzzle. In this activity, students will: use logic and the evidence to reconstruct the position of large islands and continents as they appeared 220 million years ago; understand the theory of continental movement and plate tectonics; and describe how scientists use different kinds of evidence to form theories.
