200

What is the summer solstice or June 21?
The sun rises in the northeast and sets in the northwest at this time of the year for those in the Northern Hemisphere (you and me!).

200

What is radiation inversion?

200

What is C?
One would expect the lowest temperatures to be found next to the ground on a ____________________ night. A. clear, damp, windy night B. cloudy night C. clear, dry, calm night

300

What is isotherm?
Lines connecting points of equal temperature.

300

What is increases?
The length of day (increases, decreases, does not change) between Christmas and New Year's at middle latitudes in the Northern Hemisphere.

300

What is an equinox?
Days and nights of equal length. The noon sun is directly overhead at the equator. The earth is not tilted toward nor away from the sun.

300

What is near sunrise?
At this time during a 24 hour day, radiation temperature is best developed. (at sunset, near sunrise, toward the end of morning)

300

What is 40?
The number of heating degree days for day with a maximum temperature of 30 degrees F and a minimum of 20 degrees F.

400

What is heating degree day?
Determined by subtracting the mean temperature for the day from 65 degrees F.

400

What is the angle of the sun and the length of day?
Our seasons are caused by these two things.

400

What is the southern hemisphere has more water [over 80% of the SH is covered with water]?
The reason why summers in the southern hemisphere are not warmer than summers in the northern hemisphere.

400

What is A (time of maximum solar radiation and time of maximum temperature)?
The lag in daily temperature refers o the time lag between the A. time of max solar radiation and time of max. temperature B. time of min. temperature and time of max solar radiation C. min. and max. temperature for the day

400

What is 15?
The number of cooling days for a day with a maximum temperature of 95 degrees F and a minimum temperature of 65 degrees F.

500

What is a thermograph?
A thermometer that measures temperature and records it on a piece of chart paper.

500

What is more than 12 hours and getting shorter?
In July at middle latitudes in the Northern Hemisphere, the day is ________ long and is _________ with each passing day. (less than 12 hours, more than 12 hours, getting longer, getting shorter)

500

What is D?
Northern latitudes experience 24 hours of sunlight on June 22, but they are not warmer than southern latitudes. The reason for this is: A. solar energy is spread over a larger area in northern latitudes B. some of the sun's energy is reflected by snow and ice in the north C. increased cloud cover reflects solar energy in the northern latitudes D. all of these

500

What is D?
Assuming the night will remain clear, calm and unsaturated, the predicted minimum temp is 32 degrees F. Suddenly, the wind speed increases and remains gusty throughout the night. The min. temperature will most likely be A. about the same as predicted B. higher than predicted due to release of latent heat C. much lower than predicted due to radiational cooling D. higher than predicted due to mixing

500

What is 40?
Peas are planted in Indiana on May 1. If the peas need 1200 growing days before they can be picked, and if the mean temperature for each day during May and June is 70 degrees F, the peas will be ready to pick in this many days.
