Lesson 01 -- Space Science Exam

"Seasons of the Earth"

A Product of the Virtual- Interactive-Visual Applications (VIVA) Project at Los Angeles Trade Tech College, Dr. Miguel Moreno and Prof. Auciello, co-directors.

First in a series of Science amd Technology Tests by Dr. Moreno and Prof. Auciello. The first 25 students scoring 90% or higher on this quiz will receive a "Letter of Commendation" by email.

This is a college-level astronomy quiz.  Don't guess -- No credit is given for incorrect choices.  Partial credit is given for correct choices.  90% is passing: therefore evaluate each choice carefully as "True" or "False",  and  review  answers at least once before hitting the "Submit" button.

Topics covered:  Axis of Rotation, Solstices, Equinoxes,  Celestial Equator, Tropic Zones,  Kepler's 2nd law, and Newton's 3rd law.

The chart on the left provides a visual frame of reference.   You may re-take the test as many times as you like!

1. Which of the following statements are true about Seasons?
  the Earth's distance from the Sun changes a negligible amount, though  
       this does not cause the change in seasons.
  the Earth's distance from the Sun causes the change in seasons.  
  they are caused by the  Earth's rotation axis being tipped so that first   
       one hemisphere and then the other receives Sunlight more  directly. 
  days are much longer than the nights during the summer.     
  Summer is warmer than winter (in each hemisphere) because the Sun's
       rays hit the Earth at a more direct angle during summer than during winter.        
2. On December 21 the Earth's rotation is tipped so that _________  
it is straight up and down (perpendicular) to the Earth's orbit.  
the North Pole is tipped most nearly to the Sun.   
the North Pole is tipped most strongly away from the Sun.
the Sun reaches its most southern position in the sky.  
the Sun shines exactly down on the equator.    
 
3. Which of the following are true about the Winter Solstice In the Northern Hemisphere. _________
It occurs between December 21 and December 22.  
It marks the shortest day of the year.   
The Sun appears at its lowest point in the sky.  
The Sun shines directly over the tropic of Capricorn. 
All of the above.  
None of the above.   
 
4. Which of the following are true about the Summer Solstice In the Northern Hemisphere?
In the Northern Hemisphere, it occurs around March 21st of each year.  
The Sun crosses directly over the equator.   
Day and night are of equal length.    
Highest angle of sunís ray at noon recorded in places North of Tropic of Cancer.  
None of the above.   
All of the above.  
 
5. At the summer solstice in the Northern Hemisphere ____. 
day and night are of equal length.   
longest day of the year in Northern Hemisphere and longest night in Southern Hemisphere.
the Sun is the farthest North of the celestial equator that it gets.  
the sun crosses the celestial equator.  
traditional "summer" begins in Northern Hemisphere.
 
 
6. At the Vernal Equinox ________.    
the Sun rises directly in the East and sets directly in the West.  
It is the beginning of Spring in the Northern Hemisphere.     
day-time and night-time are each approximately 12 hours at all location on Earth. 
All of the above.   
None of the above. 
 
 
7. The Earth is nearest to the Sun during our winter season in the Northern Hemisphere. From this fact and by applying Kepler's second law, we can deduce that the shortest season in the Northern Hemisphere is:  
summer  
spring 
winter
fall
each season is exactly quarter of a year.   
 
8. During which season does the Sun's rays strike the Earth at the most direct angle?
spring 
summer   
fall 
winter
depends on what hemisphere you are in  
 
9.

Which of the following statements are true about 
(1) Vernal Equinox,      (2) Summer Solstice,   
(3) Autumnal Equinox, (4) Winter Solstice:                        
(1) day and night of equal duration, (2) longest summer day, 
      (3) longest night of the year,            (4) shortest winter day,   
(1) day and night of equal duration, (2) longest summer day, 
      (3) day and night of equal duration, (4) shortest winter day,
They mark the beginning of the traditional seasons.   
(1) longest winter day in Northern Hemisphere,  (2) day and night of equal duration,
      (3) shortest summer day,                                     (4) day and night of equal duration.  
The angle of the Earth's tilt is at one of 3 positions.   

 
10. You are an astronaut taking a spacewalk to fix your spacecraft with a set of tools, including a hammer. Your life-line breaks and the jets on your backpack are out of fuel. How would you return to your spaceship safely (without the help of someone else.) 
kick your feet in a cyclic pattern. 
throw the hammer away from the spaceship. 
throw the hammer in disgust at the spaceship. 
fling your arms around in circles.  
kiss your spacecraft goodbye.
