It has certainly been a snow-filled year for many parts of the nation. Whether you got only a sprinkling of snow or an extreme downfall, test your winter knowledge skills to see how much you know about the frosty flakes!

Test Yourself!

1. If you have been out in the cold and are afraid that you have frostbite, you should rub the affected area with snow. True or False?

2. How many sides does a regular snow crystal have?
a. Four
b. Five
c. Six
d. Eight

3. Car A and Car B are traveling down ice-glazed roads at the same speed in two different locations. The temperature where Car A is traveling is 30 degrees Fahrenheit; the temperature where Car B is traveling is 0 degrees Fahrenheit. The drivers of both cars hit the brakes at exactly the same moment. If both the cars and the roads they travel are otherwise identical, which car will come to a stop first? (Hint: Hitting a tree doesn’t count.)

4. We’ve all heard of snow blindness, a condition caused by sunlight reflecting off snow. But what percentage of the Sun’s rays is actually reflected back from freshly fallen snow?

1. False. Frozen skin tissue can easily be damaged by rubbing. A better alternative is to heat the frostbitten area quickly in warm, but not hot, water.

2. c. Even if they look irregular, all snow crystals start with an underlying six-sided structure.

3. Car B will stop before Car A. The car driving on ice at 30 degrees Fahrenheit needs a braking distance twice as long as the car driving on ice at 0 degrees Fahrenheit, since ice is more slippery near the freezing point than at lower temperatures.

4. The albedo, or reflective property, of fresh snow is typically around 87 percent.
