$100 Earth’s Interior 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 the mantle. Jeopardy Menu

$200 Earth’s Interior As one descends deep into the Earth, what two propertiesof the Earth start to increase? Pressure and temperature Jeopardy Menu

$300 Earth’s Interior Name the threecompositions of the mantle. • Lithosphere  like the crust • Asthenosphere soft, can bend like plastic • Lower mantle  solid Jeopardy Menu

$400 Tides General 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

$500 Tides General Explain why the tide cycle is ~25 hours. As the Earth rotates, the moon revolves around the Earth in the same direction. Jeopardy Menu

$100 Theory of CD and SS 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

$200 Theory of CD and SS How did Wegener use climate cluesto support his hypothesis of continental drift. • Tropical plant fossils found on Spitsbergen. • Glacierscratchesfound in South Africa. Jeopardy Menu

$300 Theory of CD and SS As new crust becomes old crust at the Mid-Ocean ridge, what property of the crust (other than the age) is changing? The density is increasing. Jeopardy Menu

$400 Theory of CD and SS T/F: Subduction always occurs at a deep-ocean 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

$500 Theory of CD and SS When did the first low tide occur? • 3:48 am • 4:17 pm • 4:46 am 3:19 pm Jeopardy Menu

$100 Theory of Plate Tectonics 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 Transformboundary.  Jeopardy Menu

$200 Theory of Plate Tectonics What does the convergence of a continentalplate and a continentalplate form and what are the examples? “Triple C” Mountain Chain. 1) Ural Mountains 2) Rocky Mountains 3) Appalachian Mountains Jeopardy Menu

$300 Theory of Plate Tectonics There are two important features of the Theory of Plate Tectonics. What are they? • Earth’s crust and part of the upper mantle are broken up into sections called plates. • The plates are in constant slow motion on top of the asthenosphere. Jeopardy Menu

$400 Theory of Plate Tectonics Name the three types of plate boundary formations where volcanic eruptions can occur. • Divergent Underwater volcano • Convergent (O+C) Volcanic Mountain • Convergent (O+O)  Volcanic Island Arc Jeopardy Menu

$500 Orientation of Sun, Moon and Earth Draw the orientation of the S, M, and E during spring tides. Jeopardy Menu

$100 Seismic Waves 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

$200 Seismic Waves Name one unique feature of surface waves. Name one unique feature of P waves. Name one unique feature of S waves. • Surface waves are the most destructive. They also are received last. • P waves travel faster than S waves and can travel through solid and liquid. • S waves cannot travel through a liquid. Jeopardy Menu

$300 Seismic Waves 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? • There are 5 layers. • The 4th layer is liquid. Jeopardy Menu

$400 Past Review What are the next three phases of the moon after third quarter? Waning crescent, new moon, waxing crescent Jeopardy Menu

$500 Past Review DAILY DOUBLE! Jeopardy Menu

$500 Past Review 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

$100 Gumbo What is causing Oahu to shrink? Erosional effects. Jeopardy Menu

$200 Gumbo Who invented the first seismograph? Zheng Heng Jeopardy Menu

$300 Gumbo 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

$400 Gumbo On which dates would neap tides occur? 4th and 20th. (Will accept 21st.) Jeopardy Menu

$500 Gumbo Where are the world’s largest tidal ranges located? Bay of Fundy, Nova Scotia Jeopardy Menu
