Earthquake Exhibit Scavenger Hunt Before you go to the Shake House, explore the exhibit! Answer the questions below. Feel free to work with a partner or a team. Teacher Answer Sheet ................................................ Name ................................................ Our Planet Date Inside the Earth » Fill in the blanks. What causes plates of the Earth’s crust to move? A cycle of __heating________ and_____cooling________ in the _mantle_____ . » Match each layer of the Earth with the “ingredient” that forms it. liquid iron and nickel INNER CORE the least dense solid rock OUTER CORE solid iron INNER MANTLE solid rock UPPER MANTLE pliable (bendable) rock CRUST Life Drifts Extra credit discovery! At which type of boundary are earthquakes most likely to occur: convergent, divergent, or transform? Ratites Flightless birds evolved on different continents after Gondwana broke apart. » Draw arrows connecting each bird to the place where it evolved. Did you know? Opossums are the only marsupials found in North America! OSTRICH RHEA EMU ELEPHANT BIRD KIWI Marsupials » How did marsupials reach what is now Australia? They walked across Antarctica when the two continents were still connected. » How did opossums reach what is now North America? They walked over the land bridge at the Isthmus of Panama that connects North and South America. Exhibit Scavenger Hunt Earthquake Evidence of Plate Movement Mesosaur Fossils Mesosaurs were reptiles that lived hundreds of millions of years ago. Today’s scientists found fossils of these creatures on the southern tips of both South America and Africa. » How are these fossils evidence of plate movement? Explain your reasoning. Answers will vary. Since mesosaurs are reptiles that couldn’t swim across an entire ocean, they must have lived when the two continents were one. South America and Africa then split due to plate movement, so we find different, related fossils on each. California Faults San Francisco Shakes As you wait in line, try to fill in the blanks with answers from the sign on the window. Bonus Points! Find an example of an organism alive today that provides more evidence for drifting plates (Hint: Look at the plants behind you!) The San Andreas Fault is a _____transform________________ fault which can cause earthquakes of up to __8.0___ moment magnitude (Mw). This type of fault rarely causes the large ocean waves called ____tsunami_______ , but earthquakes in subduction zones often do. The earth along either side of the San Andeas Fault moves steadily at a rate of about __5 __ cm per year. Get Prepared On Shaky Ground Find this map on the wall. What do the different colors represent? » What kind of ground lies beneath your home? ___answers will vary_________ » What kind of ground lies beneath your school? __answers will vary_________ » Considering this, which place is safer during an earthquake? Explain why. answers will vary » After exploring the Get Prepared section of the exhibit, list 3 things that you will do with your family to prepare for an earthquake: answers will vary 1. Make an emergency plan 2. Secure your home 3. Get an emergency kit Fault Planes Can you find any faults on this map? Are the faults examples of convergent, divergent, or transform boundaries? In your head, draw arrows on the map that show the direction of plate motion.
