This is the phase of the moon where the right half is lit, and the other half is dark.
First quarter moon

Name all of the terrestrial planets and jovian planets in order. Tell which ones are terrestrial and jovian.
Terrestrial: Mercury, Venus, Earth, Mars Jovian: Jupiter, Saturn, Uranus, Neptune

Stars are organized based upon size, temperature, and this term: which means how much energy it emits.
Luminosity

Which phases of the moon do you have to be in to experience the highest tides of the month?
New moon and full moon.

What are the two terms that mean Earth is furthest and closest to the Sun? Which means which?
Perihelion: closest Aphelion: furthest
200
This is the name of the moon phase between new moon and first quarter.
Waxing crescent

Earth is said to be in the habitable zone. What does this mean?
Area where liquid, solid, and gaseous phases of water can exist. Area where life is supported. Not too hot, not too cold.

Stars are grouped by roman numeral based on their size. Using the terms: supergiant, giant, and main sequence, explain which star is what roman numeral. Also, which stars last longer and why?
Supergiant: I Giant: III Main sequence: V Main sequence dies slowest because it doesn't burn through its fuel very quickly.
200
Why are the tides much higher in the Bay of Fundy (Canada) than in the Gulf of Mexico?
The Bay of Fundy has a narrow channel which doesn't allow the water to be spread out. The only way is up, therefore water would rise extremely high. Gulf of Mexico is large and the height increase isn't as significant.

Describe the relationship between a planet's increased distance from the Sun and orbital velocity?
As you get further away from the Sun, a planet's orbital velocity decreases. It takes longer to go around the Sun.
300
This is the term that is added to moon phases to say that the moon is becoming lighter (more is visible).
Waxing

How did Saturn get it's rings and why can we see them clearly from Earth compared to the other planets?
Moon and space debris crashed together forming the ring system. Saturn had enough gravity to hold onto it. Ice reflects off light back to our eyes. The other planets do not reflect as much light.

Star A emits 10,000 times more energy than star B, but star B looks brighter. This is because of distance. We discussed two types of magnitude. Which star has which type?
Star A: absolute magnitude 10,000 times more than B Star B: apparent magnitude, looks brighter even though dim

A man goes outside during the day and observes a solar eclipse, but hears on FOX News that the moon phase for that day was a full moon. Is the man losing his mind or is the news station incorrect? Explain.
The man is not losing his mind. A solar eclipse can only occur during a new moon phase, therefore FOX News is completely incorrect in their reporting.
300
Give two pieces of evidence that liquid water may have once existed on Mars?
Ripple marks. Deltas. Polar ice caps melting.
400
Why can't you see the new moon during the day? Draw a diagram to explain this.
Because all of the sunlight is hitting the backhalf of the moon facing away from you.
400
Name a planet that is undergoing a runaway greenhouse effect. Explain what the greenhouse effect is, what causes it, and draw a diagram to support your explanation.
Venus or Earth. Solar light comes in and gets trapped in the atmosphere heating it up. Pollution of gases causes the atmosphere to become thicker, trapping in the heat.
400
What is stellar equilibrium? Must be specific.
A star creates fusion in its core which produces energy that pushes out on the star. The gravity from the star is pulling inward, wanting to crush the star. If both are balanced (pressure pulling in = energy pushing out), it is said to be in stellar equilibrium.
400
There are two types of eclipses: Lunar and Solar. Explain which moon phases corresponds to each type of eclipse. Also, break down Solar eclipses into the three subtypes and explain how they occur.
Lunar: full moon. Partial and Total. Go into Earth's shadow. Solar: new moon. Partial, Total, Annular. Partial doesn't quite cover the Sun all of the way. Total covers the Sun all of the way. Annular covers the Sun but leaves a little ring on the outside.

Put the electromagnetic spectrum in order of longest wavelength to shortest wavelength. Explain which one has the most and least energy.
Radio, microwaves, infrared, visible, ultraviolet, xray, gamma Radio has has the least energy Gamma has the highest energy

If today is October 10th and it is a waxing gibbous moon, what date will it be during a waning crescent?
October 24th

Using the formula p2 = a3, answer the following question. If planet Dinosaur is 4.2 AU away from the Sun, how many days does it take to revolve around the Sun.
3141 days

If you analyze a star's spectrum of light and find out that it's shifting toward the blue end of the spectrum, is that star moving closer or further away from you? Also, if that star was emitting a low frequency of microwaves, what color would it appear to be?
Star is moving closer to you. Blueshift. It would appear to look red. Longer wavelengths = redder
500
Using the terms perigee and apogee, explain how an annular eclipse and total eclipse occur? Also, what is happening to the moon that will make annular and total eclipses rare?
When the moon is at apogee, it is furthest away and looks smaller. This is why you have an annular eclipse. You get a total eclipse during perigee (closest) because it blocks out the sun completely. Moon is moving further away so it will look real small no matter how close or far away it is. Eclipses won't happen.
500
A planet is 39 AU away from the Sun. How many miles is that and how many years does it take to orbit the Sun?
3,627,000,000 miles 243 years to orbit, using p2=a3 formula THIS IS PLUTO!
