What is the Richter Scale?
A scale used to show the amount of energy released by an earthquake
100
Who came up with the theory of Continental Drift?
Alfred Wegener
100
What was the name of the boat commissioned to map the Atlantic Ocean with sonar?
Glomar Challenger
100
How many major tectonic plates are there?
Bonus Question (only for the team who gets the question right): What are the names of the major plates?
7
North American, South American, Pacific, African, Eurasian, Australian, and Antarctic plate.
100
What type of plate boundary is this?
Divergent plate boundary
200
What is a Tsunami?
Tidal waves that form from movement of the ocean floor during an earthquake
200
How long ago did Pangea exist?
Roughly 225 - 300 Million years ago
200
What are Mid Ocean Ridges?
Underwater mountain ranges formed at plate oceanic-oceanic divergent plate boundaries.
200
What type of Plate boundary is this?
Convergent
200
What kind of plate boundary is this?
Strike Slip
300
What is an Earthquake?
A sudden release of energy in the Earth's crust as materials slide along a fault, creating seismic waves
300
Why was Alfred Wegener's theory of Continental Drift not widely accepted by the scientific community?
Wegener had no proof or source to back up his theory.
300
Sea Floor Spreading is what type of tectonic plate boundary?
Oceanic-Oceanic Divergent
300
What two theories were combined to make the new accepted theory of Plate Tectonics?
Continental drift + Sea Floor Spreading
300
Where on this map would you find a convergent plate boundary?
South America - Nazca plate
Indian Plate - Eurasian Plate
Caribbean plate - Cocos plate
Pacific plate - north american plate
400
What is the Focus (of an earthquake)?
The location within the Earth where the slippage occurs
400
Even though Alfred Wegener did not have direct proof to back up his theory of the continents spreading, he did have three pieces of evidence that backed up his theory. What are those three pieces of evidence?
The continents fit together like a puzzle (pangea), Rock record, fossil record.
400
In relation to Earth Science, what did humans find during World War II and how?
Underwater mountains with sonar installed in submarines.
400
What happens to a tectonic plate that gets subducted and goes downward into the earth at a congergent plate boundary?
That tectonic crust will melt and become magma
400
Where on this map would you find a strike slip plate boundary?
California, west coast of north american plate
500
What is the Epicenter (of an earthquake)?
The location on the surface of the Earth that is directly above the focus
500
Have one or several members of your group come up the board and draw Sea Floor Spreading. You must label magma rising, oceanic plates, rift valley, mid ocean ridge and label with arrows which was the magma is moving and which way the plates are moving.
500
There is a wealth of evidence to support Sea Floor Spreading. List 4 pieces of evidence.
Rift Valleys, Pillow Basalts, Black Smokers, Rocks are younger (newer) at mid ocean ridges, sediments are thinner at mid ocean ridges, the rocks at mid ocean ridges alternate from pointing to north and south magnetic poles.
500
What is the only type of plate boundary that does not exist on Planet Earth?
Oceanic - Continental Divergent
500
Where on this map would you find a divergent plate boundary?
South American - African plate
Pacific Plate - Antarctic plate
