$100 Exploration Question
What percentage of the ocean is unexplored?
3
$100 Answer 95%
4
$200 Exploration Question
What directions do latitude and longitude measure, respectively?
5
Latitude measures North-South Longitude measures East-West
$200 Answer Latitude measures North-South Longitude measures East-West
6
$300 Exploration Question
What scientific innovation from the Chinese improved navigation for explorers?
7
$300 Answer Magnetic Compass
8
$400 Exploration Question
What are the three reasons humans began exploring the ocean?
9
$400 Answer Food Trade New Land
10
$500 Exploration Question
What is John Harrison best known for? How is their contribution important for ocean exploration?
11
$500 Answer Inventing the chronometer, which allows accurate navigation of longitude. Explorers can now navigate the oceans more precisely
12
$100 Earth’s Layers Question
In the order from the most dense to the least dense, what are the earths layers based on their composition?
13
$100 Answer Inner Core Outer Core Mantle Crust
14
$200 Earth’s Layers Question
What is heating the internal layers of the earth?
15
Radiation/ Radioactive decay from the earth’s inner core
$200 Answer Radiation/ Radioactive decay from the earth’s inner core
16
$300 Earth’s Layers Question
What rigid layer “floats” on top of the asthenosphere? What is this layer composed of?
17
Lithosphere (Crust +rigid upper mantle)
$300 Answer Lithosphere (Crust +rigid upper mantle)
18
$400 Earth’s Layers Question
What is two differences between oceanic crust and continental crust?
19
$400 Answer Continental Oceanic Made of granite Made of Basalt Less dense Most dense Thick crust Thin Crust
20
$500 Earth’s Layers Question
How do scientists indirectly measure the layers of the earth? Why does this measurement work?
21
$500 Answer Scientists measure earthquakes via seismographs to determine the earths layers. The seismic waves travel through different liquids in different ways, which can be measured scientifically.
22
$100 Continental Drift Question
Who is credited for the idea of Continental Drift? Was their idea widely accepted by scientists at that time?
23
-No, his idea of Continental drift was thought to be “Crank”
$100 Answer Alfred Wagner -No, his idea of Continental drift was thought to be “Crank”
24
$200 Continental Drift Question
Which force was first proposed as a mechanism for Continental Drift?
25
$200 Answer Centrifugal force
26
$300 Continental Drift Question
What is the energy that drives the movement of the lithospheric plates?
27
$300 Answer Convection Currents
28
$400 Continental Drift Question
What are two evidences that supports continental drift?
29
Continents appear to fit together like a puzzle
$400 Answer Continents appear to fit together like a puzzle Fossil Records are found on now-separated Continents
30
$500 Continental Drift Question
What is one supporting evidence for seafloor spreading?
31
$500 Answer Radiometric dating of rocks shows a relationship between the age of rocks and their location on earth Geomagnetic anomalies: the magnetic poles switch Hot Spots
32
$100 Plate Tectonics Question
Plate tectonics involves what two scientific ideas?
33
$100 Answer Continental Drift And Seafloor Spreading
34
$200 Plate Tectonics Question
What ocean feature on Earth is an example of a divergent boundary?
35
Mid-Atlantic Ridge Mid-Ocean Ridge
$200 Answer Mid-Atlantic Ridge Mid-Ocean Ridge
36
$300 Plate Tectonics Question
Crust is neither created or destroyed at what type of plate boundary?
37
$300 Answer Transform Boundary
38
$400 Plate Tectonics Question
What kind of feature is formed with the collision of two continental plates?
39
$400 Answer Mountain Ranges Ex: Himalayan mountains formed with collision of india plate and Eurasia plate
40
$500 Plate Tectonics Question
Describe the main features of plate tectonics
41
$500 Answer Earth is covered in lithospheric plates that float on the asthenosphere Oceans are constantly moving via seafloor spreading Plates move along earth via convection currents: heat from the mantle
