Words to Know - $100 What is plate tectonics? Back Words to Know - $200 Pangea split apart and moved to the locations today. Words to Know - $200 What is continental drift? Back Words to Know - $300 Someone who studies the surface of the Earth. Words to Know - $300 What is geologist? Back Words to Know - $400 Scientists who study fossils to understand history. Words to Know - $400 What is paleontologist? Back Words to Know - $500 Time periods composed of thousands, millions, and billions of years. Words to Know - $500 What is geological time? Back Earth's Layers - $100 This layer is made of many rocks. Earth's Layers - $100 What is crust? Back Earth's Layers - $200 This layer is over 6,000 degrees C. Earth's Layers - $200 What is inner core? Back Earth's Layers - $300 This layer is all liquid. Earth's Layers - $300 What is outer core? Back Earth's Layers - $400 This layer is both liquid and solid. Earth's Layers - $400 What is mantle? Back Earth's Layers - $500 This is the solid part of the first two layers. Earth's Layers - $500 What is the lithosphere? Back Plates - $100 Two plates colliding. Plates - $100 What is convergent? Back Plates - $200 Two plates separating. Plates - $200 What is divergent? Back Plates - $300 Two plates sliding past each other. Plates - $300 What is transform? Back Plates - $400 This is when one plate slides under another plate. Plates - $400 What is subduction zone? Back Plates - $500 Earthquakes, volcanoes and mountains are examples of these. Plates - $500 What are geological events? Back Continents - $100 This is a release of energy inside the Earth. Continents - $100 What are earthquakes? Back Continents - $200 This is formed when there is a convergent boundary. Example: Himalayan Continents - $200 What are mountains? Back Continents - $300 There are three different varieties of these. Continents - $300 What are volcanoes? Back Continents - $400 This is the actual physical movement of the plates. Continents - $400 What is continental drift? Back Continents - $500 This is a plate but not an actual continent (which we discussed in class.) Continents - $500 What is India? Back Fossils - $100 These give scientists clues about the history of Earth. Fossils - $100 What is are fossils? Back Fossils - $200 Fossils are found in these. Fossils - $200 What are rock layers? Back Fossils - $300 This was the original form on Earth. Fossils - $300 What is Pangea? Back Fossils - $400 This is a fern like plate found in Antarctica and South America. Fossils - $400 What is glossopteris? Back Fossils - $500 This was a freshwater reptile found on different continents. Fossils - $500 What is mesosaurus? Back
