Complete the table on the layers of the Earth. Layer Chemical make-up/State of Matter Rank thickness (km) of Rank layers. Temperature 1= thinnest of layers 4= thickest 1= coolest 4= hottest</p><p>3. How old do scientists approximate the Earth to be? 4. a. Identify and explain the difference between the two types of Earth’s crust? b. Which one is denser, explain your answer. 5. T or F The crust is divided into plates that will sometimes move. 6. What causes the plates on the crust to move? 7. a. What is the continental drift theory? b. Who proposed the continental drift theory? c. What evidence did he observe that proved that continents might be moving. 8. Why was the continental drift theory originally not accepted by most scientists at that time? 9. a. Who provided direct evidence that the plates (continental and oceanic) were moving? b. What evidence did he observe to prove plates were moving? c. Where was this located? 10. What is a ridge? 11. a. Draw a detailed diagram of seafloor spreading labeling important features/concepts. b.
