Ice Storm Warnings are issued when at least _____ of ice accumulation is expected.
Correct Answer
B. 1/4 inch
Explanation
Ice Storm Warnings are issued when at least 1/4 inch of ice accumulation is expected. This is because when ice accumulates to this extent, it can cause significant damage to power lines, trees, and infrastructure. It also poses a serious threat to transportation and can make roads and walkways extremely hazardous.

____ are raindrops that have drozen in mid-air
Correct Answer
A. Sleet pellets
Explanation
Sleet pellets are raindrops that have frozen in mid-air. When rain falls through a layer of freezing air, the raindrops become supercooled and freeze into ice pellets before reaching the ground. These pellets are smaller than hailstones and have a translucent or clear appearance. Snowflakes, on the other hand, are ice crystals that form directly from the freezing of water vapor in the atmosphere and fall to the ground as delicate, intricate shapes. Therefore, the correct answer is sleet pellets.

When the wind chill reaches -35°F, how quickly does frostbite occur?
Correct Answer
A. 10 minutes
Explanation
When the wind chill reaches -35°F, frostbite can occur within 10 minutes. Frostbite is a condition that occurs when the skin and underlying tissues freeze due to extreme cold temperatures. The wind chill factor takes into account the combination of temperature and wind speed, which can accelerate the freezing process. In extremely cold conditions like -35°F, the body's exposed skin can freeze rapidly, leading to frostbite in as little as 10 minutes. It is crucial to protect exposed skin and limit exposure to extreme cold to prevent frostbite.

Shoveling snow is easier on the body if you...
Correct Answer
D. All of the Above
Explanation
Shoveling snow is easier on the body if you push small amounts of snow, use your legs instead of your back, and take frequent breaks. Pushing small amounts of snow reduces the strain on your muscles and prevents excessive exertion. Using your legs instead of your back helps to engage the larger muscles in your lower body, reducing the risk of back injuries. Taking frequent breaks allows your body to rest and recover, preventing fatigue and overexertion. Therefore, all of the above options contribute to making shoveling snow easier on the body.

If you experience frostbite, you should...
Correct Answer(s)
A. Seek medical care
B. Put affected areas in warm water
Explanation
If someone experiences frostbite, it is important for them to seek medical care as soon as possible. Frostbite is a serious condition that can cause damage to the skin and underlying tissues. Putting the affected areas in warm water can help to gradually warm them up and alleviate some of the symptoms.

Where do winter storms typically develop?
Correct Answer
D. Colorado
Explanation
Winter storms typically develop in Colorado. This is because Colorado is located in the central part of the United States and is known for its high elevation and mountainous terrain. These geographical features create ideal conditions for the formation and intensification of winter storms, as cold air masses from the north and moisture from the Pacific can collide and interact over the Rocky Mountains. This leads to the development of heavy snowfall, strong winds, and other winter weather phenomena in Colorado.

Lake effect snow occurs when ____ air moves over ____ water.
Correct Answer
A. Cold, warm
Explanation
Lake effect snow occurs when cold air moves over warm water. As the cold air passes over the warmer water, it picks up moisture and heat from the water surface. This causes the air to become saturated with moisture, leading to the formation of snow clouds and eventually lake effect snow. The temperature difference between the cold air and warm water is crucial for this phenomenon to occur.
