Meteorology
| Question | Answer |
|---|---|
| You can see this only when the sun is at your back and it is raining in front of you | rainbow |
| Phenomenon that makes objects appear higher or lower than they actually are | mirage |
| The time after sunset or before sunrise when the sky is illuminated | twilight |
| Another name for diffuse light | scattered light |
| A ring of light encircling and extending outward from the sun or moon | halo |
| Beams of light shining downward through breaks in clouds | crepuscular rays |
| A white ring surrounding the shadow of an observer's head on a dew-covered lawn | Heiligenschein |
| Colored rings around the shadow of an aircraft | glory |
| A vertical streak of light extending above (or below) the sun | sun pillar |
| A ring of light that appears to rest on the moon or sun | corona |
| This can be seen near the upper rim of the sun at sunrise or sunset | green flash |
| The apparent twinkling of a star | scintillation |
| Formation of crepuscular rays | scatterring |
| Formation of inferior mirage | refraction |
| Formation of glory | diffraction |
| Formation of halo | refraction |
| Formation of blue skies | scatterring |
| Formation of tangent arc | refraction |
| Formation of cloud iridescence | diffraction |
| Formation of sundog | refraction |
| Formation of sunpillar | reflection |
| Formation of corona | diffraction |
| Formation of white clouds | scatterring |
| Formation of star scintillation | refraction |
| Formation of broken bow | diffraction |
| Formation of hazy skies | scatterring |
| Formation of blue moons | scatterring |
| Formation of wet looking pavement on a clear, dry, hot day | refraction |
| Formation of circumzenithal arc | refraction |
| Formation of Fata Morgana | refraction |
| If there was no atmosphere surrounding the Earth, the sky during the day would appear what color? | black |
| When sunlight strikes an object and the light is sent in all directions, the light is said to be | scattered |
| The bending of light as it moves through an object is | refraction |
| The breaking up of white light by selective refraction is | dispersion |
| The type of mirage that makes objects appear higher than they actually are is | superior mirage |
| The bending of light as it passes around an object is called | diffraction |
| For halos,tangent arcs, and sun pillar to form this must be present | ice crystals |
| If you were standing on the moon, the color of the sky would be | black |
| Which of the following processes must occur in a raindrop to produce a rainbow? | refraction, reflection, and dispersion of sunlight |
| As light passes through ice,___ light is bent the least and is, therefore observed on the __ of halos and sundogs. | red, inside |
| On a foggy night it is usually difficult to see the road when the high beam lights are on because of the __ light | scattering |
| If you looked in the general direction of the sun you would not be able to see a | rainbow |
| If the setting sun appears red you amy conclude that | only the longest waves of visible light are striking yur eye |
| Clouds in the tropics tend to move from east to west. Consequently, which rhyme best describes a rainbow seen in the tropics? | rainbow at the brak of dawn/ means, of course, the rain is gone |
| When distant mountains appear blue, it is mainly due to the __ of light | scattering |
| Rainbows form in much the same way as a mirage (T/F) | F |
| At sunrise in the middle latitudes, a sundog would appear in the west(T/F) | F |
| The Fata Morgana is actually a type of mirage(T/F) | T |
| When a star appears near the horizon, its actual position is slightly higher(T/F) | F |
| The best time of day to see a rainbow is around noon(T/F) | F |
| If the Earth had no atmosphere, the stars would be visible all the time(T/F) | T |
| Small suspended salt particles, volcanic ash, and small suspended dust particles are all capable of producing red sunrises and sunsets(T/F) | T |
| Secondary rainbows occur when two internal reflections of light occur in raindrops(T/F) | T |
| The Heiligenschein is most easily seen at night(T/F) | F |
| The best time of day to see the green flash is around noon when the sun's rays are most intense(T/F) | F |
| The formation of a circumzenithal arc is similar to that of a rainbow(T/F) | F |
