5
$100 Question Name the layers of the earth in order from OUTSIDE (surface) to INSIDE
6
$100 Answer 1.Crust 2.Mantle 3.Outer Core 4.Inner Core
7
$200 Question Name the layer where the tectonic plates are located
8
$200 Answer The Crust
9
$300 Question Name the thickest layer of the earth
10
$300 Answer The Mantle
11
$400 Question DOUBLE JEOPARDY Name the layer that contains convection currents caused by the rising and falling of magma:
12
$400 Answer The Mantle
13
$500 Question Why is the Outer Core Liquid, and the Inner Core solid, if both layers have the same composition?
14
$500 Answer The Inner Core is under a greater amount of pressure, which causes it to be compressed into a solid state
15
$100 Question Pressure, temperature and density ALL increase the deeper you go into earth’s layers. A. True B. False A. True B. False
16
$100 Answer True
17
$200 Question The DENSER a layer is, the _________ _______ its particles are. a.Closer together b.Farther apart
18
$200 Answer a. Closer together
19
$400 Answer Metals: Nickel & Iron
20
$300 Question Which graph, LEFT OR RIGHT, correctly illustrates the temperature of the CRUST of the earth compared to the other layers?
21
$300 Answer Left
22
$400 Question Both the Inner Core & the Outer Core are composed of__________.
23
Answer: iron & nickel
24
$500 Question TRUE OR FALSE: The continents (land) are less dense than Tectonic Plates. The continents and sit above the Mantle and are never pushed below the surface, unlike the Tectonic Plates, which can be pushed and melted below the surface.
25
$500 Answer True!
26
$100 Question The scientist who proposed the Theory of Continental Drift was named _______ _________.
27
$100 Answer Alfred Wegener
28
$200 Question Which of the following was not EVIDENCE that supported Wegner’s theory of Continental Drift? A. Fossils b. Mountain Chains c. Convection Currents d. Continents fit like puzzle pieces
29
$200 Answer c. Convection currents
30
$300 Question Explain how Wegner used fossils of tropical plants found on the continent of Antarctica to support his theory of Continental Drift.
31
$300 Answer The presence of Tropical Plants proves that Antarctica used to be closer to the equator (& had a warmer climate), so it must have moved
32
$400 Question Wegner’s theory of Continental Drift was not widely accepted for decades because it failed to explain HOW the continents drifted apart. Current theories explain that the Tectonic Plates move because : a. Hot Spots under the Crust b. Convection Currents in the Mantle c. Hot Magma in the Inner Core
33
$400 Answer b. Convection Currents in the Mantle
34
$500 Question Name the three of the four pieces of evidence Wegner used to support his theory
35
$500 Answer 1.Continents appear to fit together like puzzle pieces 2.Fossils of the same species found on different continents 3.Mountains chains, like the Appalachians, begin on one continent and match up to another continent 4.Evidence of glaciers discovered on continents close to the equator
36
$100 Question Name the super continent that existed on earth approximately 300 million years ago
37
$100 Answer Pangaea
38
$200 Question DOUBLE JEOPARDY TRUE / FALSE: Plates below us, and all over the world are moving, and will continue to move until the Core cools.
39
$200 Answer TRUE
40
$300 Question Plates move roughly __________per year
41
$300 Answer 2 centimeters
42
$400 Question TRUE / False Tectonic Plates are under ocean OR land, but never both.
43
$400 Answer FALSE
44
$500 Question Scientists predict that in ____ years, another super continent will form where the Pacific Ocean is currently located. A. 50 b. 1,000 c. 1 million d. 150 million
45
$500 Answer d. 150 million years
46
$100 Question END
47
$100 Answer +

55
$500 Answer A star with a magnitude of 10^-6
56
Final Jeopardy Name 3 differences between DNA and RNA.
57
Final Jeopardy Answer RNA: -1 strand -Uracil instead of thymine -3 different types -shorter -Ribose instead of Deoxyribose
