PLATE TECTONICS JEOPARDY! Earth’s Interior Theory of CD and SS Theory of Plate Tectonics Seismic waves Gumbo $100 $100 $100 $100 $100 $200 $200 $200 $200 $200 $300 $300 $300 $300 $300 $400 $400 Earth’s Interior $100 T/F: “The asthenosphere is made of both the crust and the mantle and is below the lithosphere.” False. The asthenosphere is made of only mantle. Jeopardy Menu the Earth’s Interior $200 As one descends deep into the Earth, what two properties of the Earth start to increase? Pressure and temperature Jeopardy Menu Earth’s Interior $300 Name the three compositions of the mantle. 1) Lithosphere like the crust 2) Asthenosphere soft, can bend like plastic 3) Lower mantle solid Jeopardy Menu Tides General $400 A _______ ________ forms when the force of gravity at the surface closest to the moon is ___________ than the force of the moon’s gravity on Earth as a whole. High tide, stronger Jeopardy Menu Tides General $500 Explain why the tide cycle is ~25 hours. As the Earth rotates, the moon revolves around the Earth in the same direction. Jeopardy Menu Theory of CD and SS $100 Fossils of Mesosaurus have been found in South America and Africa. Mesosaurus lived in freshwater and on land. How do Mesosaurus fossils support the past existence of Pangaea? Since Mesosaurus could only travel in freshwater, it could not have passed through oceans (salt water). Mesosaurus must have lived on both continents when they were joined. Jeopardy Menu Theory of CD and SS $200 How did Wegener use climate clues to support his hypothesis of continental drift. 1) Tropical plant fossils found on Spitsbergen. 2) Glacier scratches found in South Africa. Jeopardy Menu Theory of CD and SS $300 As new crust becomes old crust at the MidOcean ridge, what property of the crust (other than the age) is changing? The density is increasing. Jeopardy Menu Theory of CD and SS $400 T/F: Subduction always occurs at a deepocean trench and between an oceanic crust and a continental crust. False. Subduction can occur between an oceanic crust and an oceanic crust, and also between a continental crust and a continental crust. Jeopardy Menu Theory of CD and SS $500 When did the first low tide occur? - 3:48 am - 4:17 pm - 4:46 am 3:19 pm Jeopardy Menu Theory of Plate Tectonics $100 San Adreas is the location of a very famous fault. What kind of plate boundary does this fault represent? Draw an example using arrows. A Transform boundary. Jeopardy Menu Theory of Plate Tectonics $200 What does the convergence of a continental plate and a continental plate form and what are the examples? “Triple C” Mountain Chain. 1) Ural Mountains 2) Rocky Mountains 3) Appalachian Mountains Jeopardy Menu Theory of Plate Tectonics $300 There are two important features of the Theory of Plate Tectonics. What are they? 1) Earth’s crust and part of the upper mantle are broken up into sections called plates. 2) The plates are in constant of the asthenosphere. slow motion on top Jeopardy Menu Theory of Plate Tectonics $400 Name the three types of plate boundary formations where volcanic eruptions can occur. 1) Divergent Underwater volcano 2) Convergent (O+C) Volcanic Mountain 3) Convergent (O+O) Volcanic Island Arc Jeopardy Menu Orientatio n of Sun, Moon and Earth $500 Draw the orientation of the S, M, and E during spring tides. Jeopardy Menu Seismic Waves $100 What is the difference between a focus and an epicenter of an earthquake? • The focus is below the ground where the earthquake originated. • The epicenter is the location directly above the focus where surface waves originate. Jeopardy Menu Seismic Waves $200 Name one unique feature of surface waves. Name one unique feature of P waves. Name one unique feature of S waves. 1) Surface waves are the most destructive. They also are received last. 2) P waves travel faster than S waves and can travel through solid and liquid. 3) S waves cannot travel through a liquid. Jeopardy Menu Seismic Waves $300 A scientist discovered that P waves travel at speeds of 2 km/s, 4 km/s, 8 km/s, 12 km/s, and 15 km/s from the surface of a planet to the center. S waves could not penetrate past the position where P waves changed from 8 km/s to 12 km/s. What conclusions can this scientist make? 1) There are 5 layers. 2) The 4th layer is liquid. Jeopardy Menu Past Review $400 What are the next three phases of the moon after third quarter? Waning crescent, new moon, waxing crescent Jeopardy Menu Past Review $500 DAILY DOUBLE! Jeopardy Menu Past Review $500 Do solar eclipses occur during every new moon? Why or why not? No. The moon has a tilted angle, so it passes either above or below the line of the Earth mostly. Jeopardy Menu Gumbo $100 What is causing Oahu to shrink? Erosional effects. Jeopardy Menu Gumbo $200 Who invented the first seismograph? Zheng Heng Jeopardy Menu Gumbo $300 Name the three scientists (full names) we learned about in this unit and their home countries. Alfred Wegener – Germany Harry Hess – U.S. John Tuzo Wilson - Canada Jeopardy Menu Gumbo $400 On which dates would neap tides occur? 4th and 20th. (Will accept 21st.) Jeopardy Menu Gumbo $500 Where are the world’s largest tidal ranges located? Bay of Fundy, Nova Scotia Jeopardy Menu
