If you dig down until the density is 4.9 g/cm3, what layer did you reach?
How deep have humans been able to dig into the Earth?
How do we know what Earth's interior looks like?
By studying earthquakes
By studying the way the Moon's gravity pulls on each layer
By pointing an x-ray machine at the ground
By observing rock samples from each layer
What is the density of the inner core?
Why did Earth's interior separate into layers?
Differences in Mass
Influence from the Moon's Gravity
Differences in Density
Differences in Air Pressure

Alfred Wegener believed that all of Earth's continents were once a single landmass but have since broken apart. What is this theory called?
The Big Bang
What do we call the large landmass that existed when all of the continents were joined together?
What causes Earth's plates to move?
Convection Currents in the Mantle
The Dharma Initiative
What do we call the sudden, rapid shaking of Earth?
Where do earthquakes typically occur?
Along plate boundaries
At the borders of different countries
In the Mesophere
Along coastal regions
What do we call the vibrations given off when an earthquake occurs?
Why does California experience more earthquakes than New York?
California is located on a plate boundary and NY is not
NY is located on a plate boundary and NY is not
California's bedrock is weaker than NY's
NY's bedrock is weaker than California's
What is the "Ring of Fire"?
Area around the Pacific Ocean that experiences a lot of volcanic and seismic activity
The outermost of Saturn's rings that showers meteors on the surrounding area
The boundary that separates Earth's Plastic Mantle from the Stiffer Mantle
One ring to rule them all, one ring to find them, one ring to bring them all, and in the darkness bind them
The area near the Equator that receives the most direct insolation from the Sun

When a continental plate converges with an oceanic plate, which one will be pushed down?
Oceanic Plate, because it is more dense
