WHAT ARE WE INVESTIGATING? HOW IS EARTH’S SURFACE CHANGING? I What did we do? What did we observe? What have we figured out so far? How does this help answer our question? What additional questions do we have for our DQB? What questions do we think we have figured out from our DQB? We looked at phenomena that Wegener used as evidence to support his theory of plate tectonics We took a current map and recreated Pangaea We looked at evidence on ocean floor. We modeled sea floor spreading. Evidence of the same plants found across an ocean. The leaves had no way to travel that far. Evidence of same animal fossils found across an ocean. These freshwater reptiles could not swim across an ocean. Coal found in Antarctica. Coal is formed from plants that could never have survived in that climate. Earth is changing because the continents are moving. Tectonic plates are moving. Continents were in different locations. Continents were once together in a super continent Pangaea. Sea floor spreading makes new rock Volcanic activity makes new rock Plates along mid ocean ridge are Continents are moving away from each other. Volcanic activity is changing surface by adding new rock. We know Earth’s surface was different in the past. Plates come together to form mountains and volcanoes. Trenches are formed. How do the plates move? When do the plates move? What direction are the plates moving? Is there anything in between the plates? What type of rocks make up the plates? How did the plates form? When did the plates form? What causes the plate to move?
