A-100 QUESTION : Upon which part (layer) of the Earth do tectonic plates move? ANSWER : Asthenosphere

A-200 QUESTION: Which layer is the thickest and strongest layer? ANSWER: Mesosphere

A-300 QUESTION: Which earth layers are liquid? Which are solid? ANSWER: Liquid: Outer core and asthenosphere Solid: Lithosphere, Mesosphere, Inner core

A-400 QUESTION: What makes up less than 1% of earth’s mass? ANSWER: Continental and Oceanic Crust (there are only 2 types of crust)

A-500 QUESTION: Which physical layers would you pass through if you were drilling to the center of the earth? ANSWER: Lithosphere (rock sphere), asthenosphere (weak sphere), mesosphere (middle sphere), outer core, inner core

B-100 QUESTION: This drags tectonic plates sideways. ANSWER: Convection

B-200 QUESTION: This causes plates to slide down the lithosphere-asthenosphere boundary. ANSWER: Ridge push

B-300 QUESTION: Oceanic plates are forced downward because they sink and are pulled. ANSWER: Slab pull

B-400 QUESTION: Hot material rises and cool material sinks in a circular motion. ANSWER: Convection

B-500 QUESTION: Sea-floor spreading occurs at a _____. And what are the three ways that mountains can be formed? ANSWER: Mid-ocean ridge. Folding, faulting, volcanism.

C-100 QUESTION: When two plates collide and a continental/continental boundary is an example. ANSWER: Convergent boundaries

C-200 QUESTION: Plates slide past each other causing earthquakes. ANSWER: Transform boundary

C-300 QUESTION: Sea-floor spreading is what type of boundary? ANSWER: Divergent boundary

C-400 QUESTION: A rock that has no stress is called what? ANSWER: Undeformed

C-500 QUESTION: What are the three types of faults and which way do the fault blocks move? ANSWER: Normal fault: hanging wall moves down. Reverse fault: hanging wall moves up. Strike-slip fault: Horizontal movement.

D-100 QUESTION: How is a tectonic plate like an iceberg? ANSWER: There is more mass below the surface than above the surface.

D-200 QUESTION: What type of evidence is used to justify continental drift. ANSWER: Fossils are found on different continents. Glacier grooves.

D-300 QUESTION: Describe what is interesting about the shapes of the continents and how it was important millions of years ago. ANSWER: The continents all seem to fit together like a puzzle. They all formed Pangaea long ago.

D-400 QUESTION: A rock tells you that it is stressed out. What are the two types of stress that rocks can have? ANSWER: Compression and tension

D-500 QUESTION: If the layers of the earth did NOT move, where would the continents most likely be today? ANSWER: Back together like Pangaea.

E-100 QUESTION: What is the continental crust mostly made of? ANSWER: Granite

E-200 QUESTION: Who wrote about the theory of continental drift? ANSWER: Alfred Wegener.

E-300 QUESTION: How do scientists know about what is at the center of the earth? ANSWER: Seismic waves

E-400 QUESTION: What is folding, what is faulting? ANSWER: Folding: rock layers bend due to stress. Faulting: Surface along which rocks break and slide past each other.

E-500 QUESTION: What is the name of the process shown in the picture? What are points A, B, C, D? ANSWER: Sea-floor spreading, Asthenosphere / Magma, Younger, Older, Mid-ocean ridge

FINAL JEOPARDY QUESTION: Why have humans NOT dug to the center of the earth? ANSWER: It is too far, too hot and there is too much pressure.
