| Question | Answer |
|---|---|
| This is where you would have to be on the Earth to see the North star straight above your head. | North Pole |
| This is where you would have to be on Earth to see all of the stars in the sky over the course of a year. | Equator |
| This is the term for the motion of the stars during the course of a day. | Diurnal Motion |
| This is the name for stars that appear to revolve around the North Star over the course of a night. | Circumpolar Stars |
| This is the path that the Sun moves across in the sky over the course of a year. | Eliptic |
| This is the reason the Earth has seasons. | The tilt of the earths axis |
| The Sun will appear furthest north in the sky on this day. | Summer solcist |
| This is the number of times the ecliptic and the celestial equator cross paths. | twice |
| The length of the day will be equal to the length of the night on these two days of the year. | equinoxes |
| If it is Summer in the northern hemisphere, then in the southern hemisphere it is this season. | Winter |
| The third quarter moon rises at this time. | midnight |
| The full moon will set at this time. | six AM |
| This phase of the moon will rise at sunrise. | new moon |
| The moon must be in this phase in order for a solar eclipse to occur. | new moon |
| The moon must be in this phase in order for a lunar eclipse to occur. | full moon |
| This is the best time to view a superior planet | opposition |
| This is the name for the motion of a planet when it appears to be moving backwards compared to the background stars. | retrograde motion |
| Kepler’s laws describe this in the solar system. | motion of the planets |
| Kepler’s second law states that a line joining a planet and the Sun will sweep out equal areas in equal this. | time |
| Kepler’s third law states this | Further a planet is away from the sun the longer it takes to go around it |
| This astronomer came up with the geocentric model of the solar system. | ptolemy |
| This astronomer was the first to propose the idea of a heliocentric model of the solar system. | cupernicus |
| This astronomer rejected the idea of a heliocentric model of the solar system because he couldn’t measure the distance to a nearby supernova using parallax. | Tycho |
| This astronomer was the first to realize that the planets orbit the Sun in ellipses. | Capler |
| This was the first astronomer to use a telescope to look at the sky. | Galelaou |
| This is the physicist who came up with the mathematical equation that describes the force of gravity between two objects. | Newton |
| Newton’s universal law of gravitation states that the force between two objects can be found from these two properties of the objects. | Mass/Distance |
| This is what will happen to the force between two objects if the distance between the objects increased. | Less force |
| This is the reason we have tides on the Earth. | The moon |
| This quantity of an object would change if it were brought from the Earth to the Moon. | Weight |
| This type of electromagnetic radiation that has the highest energy. | Gamma rays |
| This type of radiation has the longest wavelength. | Radio waves |
| This type of radiation generally measures the amount of heat given off by an object. | Infered |
| This form of electromagnetic radiation is higher in energy than radio waves but lower in energy than infrared. | Microwaves |
| This type of radiation is the next highest in energy after visible light. | Ultraviolet |
| When electrons jump from a lower energy level to a higher energy level this is what happens to a photon | absorbs light |
| When electrons jump from a higher energy level to a lower energy level to this is what happens to a photon. | Emits light |
| A blackbody will produce this type of spectrum | Continuous spectrum |
| A hot gas will produce this type of spectrum. | Emition spectrum |
| A cool gas in front of a blackbody object will emit this type of spectrum. | Abortion Spectrum |
| The two main types of optical telescopes are refracting and this type which is more commonly used in research. | Reflecting |
| This quantity of a telescope contributes to the most light gathering power AND the best angular resolution. | Bigger the mirror |
| This is what we see when white light passes through a prism or diffraction grating | Rainbow |
| This is the reason for using interferometry with several radio telescopes. | Better angular resolution |
| This is the reason for using interferometry with several radio telescopes. | Speed |
