Geology UNLEASHED
What is “Earth Science”?
The study of the Earth!
What is the lithosphere?
The upper 100 Km of Earth,
including the upper, rigid mantle.
What’s the difference between an observation & inference?
Observation = something you see/measure
Inference = An educated explanation for why you see what you see.
What are the 3 rock categories? How are each created?
1). Metamorphic
2). Igneous
3). Sedimentary
If it takes 50 seconds for the P-wave to arrive at Buffalo, about how long would it take for the S-wave from this same earthquake to arrive at Buffalo? [Refer to the Earth Science Reference Tables.]
About 50 seconds
Define Density, Volume, & Distance.
Density= amount of particles in a substance.
Volume =amount of space something takes up
Distance = length (in meters)
Describe the Earth’s Mantle
According to the Reference Table, how deep is it located?
Solid, but elastic in nature. Due to high temperatures and high pressure.
Mantle = 100-2900Km deep
What’s a scientific LAW vs Theory?
Law= something that is accepted/proven as an undisputed scientific fact. Can also be solved with an equation.
Theory= A heavily supported inference.
It’s “#so totally” true that rocks make up minerals…. like OMG.
TRUE or FALSE?
That statement is SO wrong...I don't even know what to say.
What does P & S Wave Stand for?
Are they related to plate tectonics in some way? How so…?
P Wave = Primary
S Wave = Secondary
Draw a Subduction Diagram Vs Divergence Vs Transform

The North America Plate and the European plate are moving ( ) from each other. This is an example of a ( ) plate boundary.
1). Away
2). Divergent
What is a topographic profile?
Represents the relief of selected terrain from point A to Point B.
What are the two most abundant elements by mass found in Earth's crust?
Oxygen /Silica
Aluminum ranks #3

42.4° N, 76.5° W
According to the Earth Science Reference Tables, which sedimentary rock would be formed by the compaction and cementation of particles 1.5 centimeters in diameter?
Conglomerate/Breccia
At which location will the highest altitude of the star Polaris be observed?
North Pole
Mr. Hawley has successfully “Hacked the Mainframe” in the Elder scrolls PC. He is now #1 in the world. Ms. Hallock tries to trick him by selling him a Diamond but Thomas claims it’s quartz. What are the properties of quartz?

Transparent/Translucent
Your friend is playing RuneScape (big time) and trolling all the “Noobs” with his “knowledge.” He/her tries to roast you by stating that the earth is round. But you say…
Oblate Spheroid
Volcanic activity like that which produced the Hawaiian Islands is usually closely correlated with
Earthquakes
According to the Earth Science Reference Tables, which sedimentary rock is composed of fragmented skeletons and shells of sea organisms compacted and cemented together?
Limestone
Difference between an “epicenter” and “focus”. Can these cause a tsunami?
Focus= Place in Earth where earthquake occurred
Epicenter = Place on surface of earth directly over focus
Tsunami?= Yes if it occurs under the ocean/body of water.
