The Earth’s crust and upper mantle make up the mechanical layer known as the ___________.
LITHOSPHERE
100
What process causes rocks to simply break down into smaller pieces due to nature?
WEATHERING
100
What is last step of the scientific method?
COMMUNICATE or SHARE RESULTS
100
What tool would we need to use (along with a graduated cylinder) to measure the *rate* of water dripping out of a leaky faucet?
A TIMER (clock, stopwatch, etc) since we need to measure time (in addition to volume)
100
Tall mountains – like the Himalayas in Asia or the Andes in South America – typically form at which type boundary: divergent, convergent, or transform?
CONVERGENT
200
Beside location, what is one primary *difference* between the inner core and outer core?
OUTER CORE is liquid, cooler, and less dense (magnetic field) INNER CORE is solid, hotter, and more dense
200
Lava spewing out the top of a volcano (or flowing out of fissures) creates *which type* of igneous rock?
EXTRUSIVE (igneous)
200
The variable in an experiment that a scientist simply observes and records the effect of is called the ________________.
DEPENDENT (variable)
200
What TWO processes must occur to turn metamorphic rock into igneous rock?
MELTING, then COOLING
200
Metamorphic rock *without* distinct layers is called _______________.
NON-FOLIATED (metamorphic)
300
The tectonic plates float on top of which mechanical layer?
ASTHENOSPHERE
300
Rock made up primarily of broken pieces of rocks and minerals compacted and cemented together forms *which type* of rock?
SEDIMENTARY (Bonus 50 pts for "DETRITAL sedimentary")
300
True or False: "A good experiment has at least two independent variables"
FALSE - Good experiments always have only ONE independent variable
300
Evaluate the following statement: "The conclusion in an good experiment must always support the original hypothesis, otherwise the experiment was not properly conducted."
FALSE - A valid conclusion (once the experiment is completed) may or may not support the original hypothesis - but it can still have been a good experiment!

Density = mass / volume What two tools from our lab would you use to find the density of a super-sized rectangular box of Sour Patch Kids?
Triple Beam Balance (mass), and Ruler (volume = length x width x height)
400
How is the density of the Crust different than the other layers
CRUST has a lower density (rises to the top) Mantle, Outer Core, and Inner Core have a higher density (sinks)
400
The property of a mineral that allows it to "break along a smooth, flat surface" is called _____________.
CLEAVAGE
400
A graduated cylinder is the best way to measure the volume of liquids between 1 mL and 20 mL. However, what tool might you use to measure larger amounts (like 500 mL) of liquid?
BEAKER
400
What type of tectonic plate boundary exists below Hawaii?
NONE. No tectonic plate boundary exists - it's a hot spot.
400
Which layer of the Earth has the greatest effect on a compass?
OUTER CORE
500
A scientist measured how much two continental plates drifted apart during one year, but only wrote down “8” without recording her units. What should the units be for her observation?
CENTIMETERS
500
On the Mohs hardness scale... gypsum=2 fluorite=4 quartz=7 Which of these minerals could NOT scratch apatite (hardness =5)?
"GYPSUM and FLUORITE" (both less than 5)
500
Mike the zookeeper wants to know how to make elephants jump higher. He feeds one group extra high-protein food, and decides to also replace their water with vitamin water. The other group gets normal food and normal water. After observing both groups, Mike concludes that extra high-protein food makes them jump higher, and probably works on people, too. What is wrong with the way he set up his experiment?
TOO MANY INDEPENDENT VARIABLES. (He should only change ONE factor and leave the rest the same - can't change the food AND the water)
500
The Great Rift Valley in eastern Africa is formed from a divergent boundary. Scientists believe is likely that some of eastern Africa will eventually separate from mainland Africa and become its own continent in a few _________ years.
MILLION
500
What do we call the long string of volcanoes and subduction zones that surround the Pacific Ocean?
The RING OF FIRE
