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 hypothesis?
What is continental drift?
100
What happens at a convergent tectonic plate boundary?
What is two tectonic plates collide with one another, causing subduction and or mountain building?
100
How do volcanoes form at convergent plate boundaries? 

When the subducting plate (one that goes under usually oceanic) melts and the pressure causes magma to rise to the surface: creating a volcano. 

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 pushing 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

Where and how does a volcano form at a divergent plate boundary. 

When two plates move away from each other magma from the mantle rises causing volcanic activity under the ocean at mid-ocean ridges. Is this also referred to as sea floor spreading. 

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 coninental plate collide, what is formed on the continental plate.
What are mountains (probably volcanic arc)?
300
What happens at a transform boundary?
What is 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
What will happen to the graph of the 'p' and 's' waves the further the recording station is from the epicenter.
What is the distance between them on the graph will increase?
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 recion of lower temperature to a region of higher temperature?
400

What would be the major reason there are no major earthquakes recorded in the interior of the continent of Africa?

What is the entire continent of Africa is located on a single continental tectonic plate?

400
What causes the plates to move?
What are convection currents in the mantle?
400

What determines that viscosity of lava or magma? 

What is the amount of silica ?

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

How do continents move?

What is continents move along with the plate they are part of?

500

Explain what a fault line is and its relationship to plate boundaries and earthquakes.

Not all fault lines are plate boundaries. However, all plate boundaries are fault lines. A fault line is a crack in the crust where earthquakes occur.

How does amount silica in lava and magma affect volcanic eruptions? 

Lava and magma high in silica will have thicker magma/lava causing more violent and explosive eruptions whereas lava/magma lower in silica will move more freely like water and have less violent and explosive eurptions.
