Density & Stuff
What is the formula to solve for density?
D = m/V
(Density equals mass divided by volume.)
This is the formula for a rate of change.
What is... ROC = (change in value)/time ...?
(What is: The rate of change is the change in that problem's value, divided by the amount of time?)
This type of plate boundary is most responsible for earthquakes felt on the surface (for example, at the San Andreas Fault).
What is a transform boundary?
Every layer of the Earth (not counting surface water) is part of this "sphere" of the Earth.
What is the geosphere?
This is what we call lava that is underground before it is exposed to air or water.
What is magma?
If you are asked about which is heavier, a kilogram of platinum or a kilogram of wings, this would be a good follow-up question.
What is: Aren't both the same mass/weight?
(Or something like that.)
[Densities are very different.]
This is what is typically plotted on the y-axis of a graph.
What is the dependent variable?
Divergent boundaries are responsible for this two-word phenomenon at the bottom of a large body of water, such as an ocean.
What is seafloor spreading?
The Earth's core is mostly made of these two metals.
What are iron & nickel?
This is the density range for the mantle.
What is 3.4-5.6 g/cm3?
It's the density of water at 3.98 degrees Celsius.
What is 1.0 g/mL?
(What is 1 g/cm3?)
This is the rate of change for a car that travels 100 miles between 9 AM and 11 AM.
What is 50 mph?
This type of boundary is present at/above subduction zones.
What is a convergent boundary?
These two layers comprise the lithosphere.
What are the crust and rigid mantle?
This kind of zone happens at an oceanic-continental convergent boundary, in which old seafloor is recycled.
What is a subduction zone?
This is the density of a sample with a volume of 3 mL and a mass of 6 grams.
What is 2 g/mL?
This is a graphing relationship that involves the independent variable increasing while the dependent variable remains the same.
What is a static relationship?
Between the North American Plate and the Juan de Fuca Plate, this plate is the one that is subducting.
What is the Juan de Fuca Plate?
This layer is also called the plastic mantle.
What is the asthenosphere?
Tectonic plates moving over these specific points in the asthenosphere can cause volcanic eruptions.
What are hot spots?
Given a density of 20 g/cc, and a volume of 10 cc, what is the sample's mass (in kg)?
What is 0.2 kg?
(In grams, it's 200 g)
This is the strange request that the Regents Exam will have when you plot line graphs by hand.
What is putting circles around data points?
These are usually formed / "built" as a result of a continental-continental convergence.
What are mountain ranges?
Between granitic continental crust and basaltic oceanic crust, this is the denser type of crust.
What is oceanic crust?
Yes or No: Humans have been able to dig to the center of the earth.
What is NO?
(That is the plot of many fictional movies and TV shows, including The Core.)
