Question 1
When a solid changes to a liquid, we say it's melting. What do we call it when a gas changes into a liquid?
-
ASolidification
-
BVaporization
-
CLiquidation
-
DCondensation
Condensation
The reverse of vaporization is condensation, the change of the physical state of matter from a gas into a liquid. This phenomenon occurs when water droplets form due to cooling air, such as those that we see on a cold drink on a hot day.
Question 2
As of October 2008, there are 193 known moons orbiting planets in our Solar System. Discovered on October 10, 1846, Triton is the largest moon of what planet?
-
AEarth
-
BNeptune
-
CPluto
-
DMercury
Neptune
Jupiter's moon Ganymede may be the largest moon in the Solar System, but with a diameter 5.5% that of Neptune, Triton is the largest moon relative to its planet in terms of diameter.
Question 3
We're all familiar with the mosquito trapped in amber in the movie 'Jurassic Park', but what was that amber made from?
-
AResin
-
BSap
-
CCoal
-
DBark
Resin
Amber is a result of the fossilized resin from ancient forests. In response to destruction or injury, plants secrete aromatic resins for their protective benefits. These resins often trap various debris such as seeds, leaves, feathers, and insects.
Question 4
Grains are deeply embedded in the history of human diets, but which one takes the cake for the highest level of worldwide production by weight?
-
AWheat
-
BRice
-
CCorn
-
DPotatoes
Corn
As of the 2018/2019 census, corn was the most heavily produced grain at a whopping 1.09 billion metric tons. Despite being a staple in recipes around the world, most grain in the U.S. is used as animal feed.
Question 5
They say that our eyes are the windows to our soul, but what do we call the most attractive, pigmented part of the eye?
-
ALid
-
BRetina
-
CPupil
-
DIris
Iris
The iris is a thin, circular structure in the eye that not only gives our eyes their distinctive colors but also controls the amount of light reaching the retina. Under super bright conditions, the iris contracts to block the amount of light entering the eye.
Question 6
In terms of weather, cirrus, cumulus, and stratus are all different types of what?
-
ATornadoes
-
BLightning Strikes
-
CClouds
-
DRain Patterns
Clouds
Cirro-form clouds are wispy, white-ish and exist high in the sky while cumulo-form appear as white fluffy cotton balls and strato-form create a blanket-like cover.
Question 7
Sometimes referred to as plant science, plant biology, or phytology, the branch of biology focused on plant life is called what?
-
AAnatomy
-
BBotany
-
CZoology
-
DGeology
Botany
Botany is the scientific study of plants, and if that doesn't sound interesting, consider the fact that some plants are actually carnivores! That's right - certain species gain their nutrients by eating various small insects and spiders.
Question 8
Many are partial to one temperature scale over the other, but there is one spot where the two exist in harmony. At what temperature are both the Celsius and Fahrenheit scales the same?
-
A96 degrees
-
B0 degrees
-
C-32 degrees
-
D-40 degrees
-40 degrees
Celsius, or centigrade, is equal to Fahrenheit at -40 degrees based on the simple algebra of setting ºF = ºC and solving for one side. It's nice that they found that mutual ground, but I don't think anyone wants to hang out and celebrate in -40 degrees.
Question 9
No, that's not a star - it's the brightest planet in the night sky! Do you know which one it is?
-
AVenus
-
BMars
-
CSaturn
-
DJupiter
Venus
Next time you look up at the sky shortly after sunset or right before sunrise, you'll see Venus as the brightest object in the night sky other than the moon. It's not only the brightest planet to us on Earth, but Venus is also the brightest planet in the Solar System.
Question 10
The genetic information held in DNA is responsible for the development, functioning, growth, and reproduction of all known organisms. What do we call a single piece of coiled DNA?
-
ARNA
-
BChromosome
-
CBackbone
-
DMitochondrion
Chromosome
Chromosomes are threadlike structures made from nucleic acids and protein, which carry genetic information in the form of genes. In the 46 chromosomes of most humans, there are roughly 30,000 genes!
Question 11
Deserts are diverse landscapes filled with unique plants and wildlife not found anywhere else on Earth, but what hot desert is larger than all the others?
-
ASahara
-
BGobi
-
CKalahari
-
DNile
Sahara
Spanning over an astounding 9,200,000 square kilometers, the Sahara Desert is the largest and hottest desert on Earth. To put that number into perspective, the United States covers 9,826,675 square kilometers.
Question 12
These days, people are very conscious of the food they eat, and luckily, there are plenty of methods for ensuring safe consumption. What is the name of the process which involves heating a liquid or food to kill pathogenic bacteria?
-
ASanitation
-
BBoiling
-
CDetoxification
-
DPasteurization
Pasteurization
Pasteurization is the process by which certain liquids and foods are treated with mild heat to destroy pathogens and extend shelf life. We most commonly associate pasteurization with dairy products, but many beers, syrups, canned foods, and juices are also pasteurized.
Question 13
Punchbowl, Horsetail, Chutes, Cascades, and Block are all different types of what natural water feature?
-
ARiver
-
BWaterfall
-
CPool
-
DLake
Waterfall
Depending on the way they descend, waterfalls are classified in 10 different types including Punchbowl, Horsetail, Chutes, Cascades, and Block. Technically speaking, a waterfall is a place where water flows over a steep drop in the course of a stream or river.
Question 14
Despite the efforts made by wildlife conservationists, many plants and animal species remain at risk. In biology, what is the term for the death of an entire species?
-
ARejuvenation
-
BExtinction
-
CEndangerment
-
DPreservation
Extinction
Extinction is the termination of an organism or of a group of organisms under natural or human-induced circumstances. Experts estimate that between 0.01 and 0.1% of all species become extinct each year. To put the low number into perspective, that means between 200 and 2,000 extinctions occur every year based on the roughly 2 million different species on our planet.
Question 15
Variations in hair, eyes, and skin color bring beautiful uniqueness to the human race. What substance do we have to thank for our differing pigments?
-
AKeratin
-
BMelanin
-
CBiotin
-
DEstrogen
Melanin
Melanin is the pigment which gives human skin, hair, and eyes their different colors. Depending on how much a population has been exposed to the sun historically, the levels of melanin will be higher or lower.
Question 16
Freedom of speech wouldn't exist without the highly-evolved voice box that allows humans to speak their minds. What's another name for our voice box?
-
ALarynx
-
BTrachea
-
CEsophagus
-
DValve
Larynx
The larynx is a hollow, muscular organ that creates an air passage to the lungs while holding the vocal cords. Our larynx actually works quite similarly to a reed instrument as air rushes through the vocal cords to produce sound.

-
AExplorer
-
BSputnik
-
CChallenger
-
DSkylab
Sputnik
Sputnik 1, launched by the Soviet Union on October, 4 1957, was the first artificial Earth satellite. The satellite orbited the Earth for three weeks before its batteries died, then it slowly made its way back into the atmosphere.

We all know how to flip a switch and turn on a light, but how do we typically measure that electric power?
-
AJoules
-
BTime
-
CWatts
-
DVolts
Watts
Named in honor of James Watt, the inventor of the steam engine, a watt is the unit of electrical power equal to 1 ampere under the pressure of 1 volt. 1,000,000 watts is called a megawatt and is used to denote how much electricity is needed by large towns or cities.
