Which compositional layer of the Earth is the thinnest?
What is the crust?
100
Most divergent boundaries lie under the world's oceans. Which of these is a process that occurs at divergent boundaries: subduction of old crust, formation of new crust, plates slide past each other, or continental collisions occur?
What is formation of new crust?
100

Scientists think continents were once a large single landmass that broke apart and then the continents slowly DRIFTED to their present locations. What is the name given to this theory?

What is continental drift?

100

What happens at a convergent tectonic plate boundary?

What are two tectonic plates collide with one another, causing subduction and or mountain building?

100

This wave travels faster, records a lower signal strength, first to arrive, and causes less damage.

What is the 'p' wave?

200
How is the outer core different than the inner core?
What is the outer core is liquid and the inner core is solid?
200
Subduction is one plate pushing underneath another plate. If an oceanic plate and a continental plate collide, which one will push underneath the other one and why.
What is the oceanic plate will push under because it is denser?
200
Tectonic plates puching into each other is what kind of boundary?
What is a convergent boundary?
200

Define epicenter.

What is the position on the Earth's surface where an earthquake begins.

200

This wave travels slower, records a stronger signal strength, is formed when "s" and "p" waves reach the surface and cause more damage due to the rolling motion. 

What are the 'L' waves.

300
Going from inner layer to outer layer, name the 3 compositional layers.
What is the core, the mantle, and the crust?
300

When an oceanic plate and a continental plate collide, what is formed on the continental plate.

What are volcanic mountains

300

What happens at a transform boundary?

What are two plates move horizontally past one another?

300

An Earthquake in City A registers 5.6, City B 7.8, and City C 6.8. Which city had the strongest earthquake?

What is City B?

300

How many seismographs are required to record the exact location of an earthquake epicenter? 

What is 3?

400
The Earth's core is made up of mainly two elements, name them.
What are nickel and iron?
400

Explain a convection current.

What is the transfer of energy from a region of lower temperature to a region of higher temperature?

400

Mountain Ranges that are not volcanic form due to what type of boundary movement? (Be Specific) 

What is the convergent boundary of continental and continual crust, due to no subduction?

400

What causes the plates to move?

What are convection currents in the mantle?

400

Which earthquake will be more violent? Earthquake A, which has a shallow focus and a ricter scale of 1.2, or Earthquake B, which has a deep focus and ricter scale of 1.2? 

What is Earthquake A, shallow focus and 1.2

500
This physical layer is divided into pieces called tectonic plates.
What is the lithosphere?
500
Describe a divergent boundary.
What is the plates seperate?
500

____ is the gravitational force pushing plate below the subduction zone, _____ is the force generated by the divergent boundary of new seafloor being generated pushing the crust outward.

What is slab-pull and ridge push? 

500

'P' waves are the primary waves and 's' waves are secondary waves. Explain why 's' waves are secondary.

"s" waves can not travel through liquid 

500

This type of seismic wave causes the most damage.

What are 'L' waves?
