Name: Date: Period: Directions: Please go to Google Classroom and locate the “Slip…Slide… Collide” post. There is a link to this simulation where you will get to investigate the interior and the functions of the Earth. There are three levels to conquer and as you complete each section, please complete this guided worksheet. Good luck and “For Science!” LEVEL 1 EARTH’S INTERIOR Background: Find out about the compositional and mechanical nature of the Earth’s interior LAYER NAME 1-2 FACTS TRUE OR FALSE INNER CORE ANSWERS VARY This layer is made of iron and some nickel. (True or False) OUTER CORE ANSWERS VARY This layer is a solid. (True or False) MANTLE ANSWERS VARY This layer is solid but convection currents are still able to flow (True or False) CRUST ANSWERS VARY There are two types of crust on Earth. (True or False) OCEANIC CRUST ANSWERS VARY This layer is the LEAST dense type of crust. (True or False) CONTINENTAL CRUST Lithosphere (a layer within the Mantle) Asthenosphere (a layer within the Mantle) ANSWERS VARY ANSWERS VARY ANSWERS VARY Oxygen and Silica are the two most abundant minerals in this type of crust. (True or False) This is a combination layer which is part crust and part mantle. (True or False) This layer houses the convection currents that move the lithospheric plates. (True or False) LEVEL 2 PLATE TECTONICS Background: Find out about how the lithosphere is broken down and how the plates move 1. Because the Earth has a particularly weak zone (the asthenosphere) below the lithosphere, plates are able to MOVE/SHIFT around. 2. The ________________ plate is the largest lithospheric plate. a. North American b. Pacific c. African 3. During the Cambrian Period, the largest landmass was known as GONDWANA 4. During the Triassic Period, this LARGE landmass existed on Earth. a. Laurentia b. Godwana c. Pangaea 5. The _________________ Mountains formed when India collided with the Asian Plate a. Appalachian b. Himalayas c. Andes 6. One hundred years into the future, North and South American will continue to ________. a. Grow in size b. Develop mountain ranges c. Drift apart LEVEL 3 PLATE BOUNDARIES Background: Learn about how each type of plate shifts and which features form at boundaries 1. DIVERGENT plate boundaries occur where plates are drawing apart from each other. 2. CONVERGENT plate boundaries occur when adjacent plates move towards each other. 3. In some places, plates slide sideways past each another, called a TRANSFORM boundary. 4. Complete the following table on Plate Features FEATURE Trench Subduction Zone Volcano Mountains Mid-Ocean Ridge Faults BOUNDARY CONVERGENT (ocean-continent) CONVERGENT (ocean-continent) CONVERGENT (ocean-continent) CONVERGENT (continent-continent) DIVERGENT (ocean-ocean) TRANSFORM (ocean-ocean) FACT ANSWERS VARY ANSWERS VARY ANSWERS VARY ANSWERS VARY ANSWERS VARY ANSWERS VARY 5. True or False. Earthquakes are common at or near plate boundaries. 6. True or False. All plate boundaries produce the same type of plate boundary features.
