Exam 3: Seasonal and Daily Temperatures

Hypothermia is most common in ____.

The north-facing side of a hill in a mountainous region in the United States tends to be a better location for a ski run than the south-facing side.

Explain why runners on a clear, windless, summer afternoon may experience air temperatures of over 50 degrees Celsius (122 degrees Fahrenheit)at their feet and only 32 degrees Celsius (90 degrees Fahrenheit)at their waist.

Describe the seasons that you would experience in Australia in comparison to those in Germany.

The wind-chill factor ____.

Even though the poles have 24 hours of sunlight during the summer, the average summer temperature there is nonetheless below 0 degrees Fahrenheit.

In the Northern Hemisphere, south-facing mountain slopes normally have a smaller diurnal range in temperature than north-facing slopes.

In some years around the middle of autumn, there is an unseasonably warm spell, especially in the eastern two-thirds of the United States. This warm period is commonly referred to as ____________________.

Another name for an infrared sensor is ____.

The combination of heating and cooling degree days gives a practical indication of the energy requirements over the year.

Explain why experts sponsored by the World Meteorological Organization declared the temperature of 134 degrees Fahrenheit, in year 1913, to be the world's hottest officially measured temperature.

The Sun is directly overhead at Mexico City (latitude 19 degrees N)____.

The ____________________ branches of a fruit tree are most susceptible to damage in cold weather.

Because air temperatures normally decrease with increasing height, trees found on the cooler north-facing side of mountains are often those that usually grow ____.

If it is winter and January in New York City, the season in Sydney, Australia is ____________________.

The first sign of hypothermia is ____.

During the Northern Hemisphere's summer, the daylight hours in northern latitudes are ____________________ than in middle latitudes.

This type of thermometer has a glass bulb attached to a sealed, graduated tube about 25 cm (10 in.)long. A very small opening, or bore, extends from the bulb to the end of the tube. A liquid in the bulb (usually mercury or red-colored alcohol)is free to move from the bulb up through the bore and into the tube. When the air temperature increases, the liquid in the bulb expands, and rises up the tube. When the air temperature decreases, the liquid contracts, and moves down the tube. Hence, the length of the liquid in the tube represents the air temperature.

In the Northern Hemisphere, summers are warmer than winters, because Earth is closer to the Sun in July.

Cold, rainy days often feel warmer than dry days because air conducts heat away from the body better than water.
