THIS plate boundary is where plates are moving AWAY from each other
Divergent
100
This is the main mechanism responsible for the movement of the crustal tectonic plates
Convection in the asthenosphere (upper mantle)

The Richter Scale is a much more reliable rating system compared to the Mercalli Scale. Why is this true?
The Mercalli Scale can be subjective because it is based on human experiences. The Richter scale is based on data

What is the spreading rate at the Southeast Indian Ocean Ridge?
7.4 cm/year

What NFL team won the first ever Super Bowl?
The Green Bay Packers
200
TRUE or FALSE: All earthquakes occur along plate boundaries
FALSE! MOST, not ALL
200
Fossils of this organism have been found in Africa, India, and Antarctica. These landmasses are vast distances apart, some with large bodies of water in between them. Explain with evidence how these fossils can be found in these various locations
The landmasses used to be TOGETHER before the plates moved them to the locations they are in today
200
THIS form of seismic energy arrives at a seismic station first, and can travel through solids, liquids, and gases
Primary Waves (P-waves)
200
What plate boundary is found between the Philippine Plate and the Pacific Plate?
Convergent
200
This country star founded a non-profit organization to benefit public schools in Tennessee?
Dolly Parton
300
This plate boundary is where plates slide past each other, grinding and building up energy and pressure
Transform
300
The age of oceanic crust located near a mid-ocean ridge is YOUNGER than crust farther away from a ridge. Explain why this is true.
Plates are diverging, with new crust forming in the center of the ridge. New crust=younger
300
Earthquakes and volcanoes are common in this are of South America - Chile. Provide evidence for this claim.
Located on a plate boundary/subduction zone
300
Describe the motion of the plates at the boundary between the North American Plate and the Pacific Plate near California.
Transform boundary = slide past each other
300
How many flavors are in a box of Froot Loops?
ONE
400
When two crustal plates of EQUAL density converge, what can form as a result?
Mountains
400
The movement of the tectonic plates are often compared to what human experience over one year?
Fingernail growth
400
Outpouring of lava over a widespread area accumulates over many years to form this type of volcano. One of the largest in the world can be found in Hawaii!
Shield Volcano
400
State a location where new crust is being formed
vary
400
What is the common name for the third and final set of molars that most people develop?
Wisdom Teeth
500
Explain in your own words how a SUBDUCTION ZONE is formed in terms of density, movement of the tectonic plates, etc.
As plates of different densities move towards each other at a convergent plate boundary, the MORE dense plate goes underneath the other plate.

This is a fossil of a palm tree branch that was found in Antarctica. How is this possible?
Antarctica used to be in a different location, closer to the equator/tropical region - allowing plants like this to be able to grow on this landmass
500
This is seismograph data from three different stations at three different locations. Which station is the CLOSEST to the epicenter of the earthquake. How do you know?
Top - waves arrive first, more intense waves, P and S waves close together
500
The Arabian Plate and the African Plate boundary is diverging. Describe what might happen here a few million years into the future.
Move apart, open up the land, rift, new ocean, etc
500
The largest desert on earth is located here
Antarctica
