The altitude would be less than shown
Air temperature is regulated partly by the percentage of carbon dioxide in the air. Which of the following statements is correct?
The carbon dioxide content of the air is decreasing due to the burning of fossil fuels
What is the primary reason New York State is warmer in may than in February?
The insolation in New York is greater in May

The following diagram represents a portion of earth's surface that is receiving insolation. Positions a,b,c, and d are located on earth's surface. At which position would the intensity of insolation be greatest
4-D
The factor that contributes most to the seasonal temperature changes during a year in New York State is the changing

Which line represents the equator?
BF
Six months after the date indicated by the diagram, which point would receive the sun's vertical rays at noon?
C
Which point on earth's surface is receiving the greatest intensity of isolation?
C
If dust particles are added to the atmosphere, the amount of insolation reaching the ground will probably
Decrease
Between the years 1850 and 1900, records indicate that Earth's mean surface temperature showed little variation. This would support the inference that
Earth was in heat balance
A heating of the normally cold ocean waters of the eastern Pacific Ocean off the coast of South America is called
El niño
What is the usual cause of the drop in temperature that occurs between sunset and sunrise at most New York locations?
Ground radiation
The most logical conclusion that can be made from the relationship between the altitude of the sun throughout the day and the amount of insolation is that, as the sun's altitude
Increases, the insolation increases
Which form of electromagnetic energy is radiated from earth's surface with the greatest intensity?
Infrared rays
Electromagnetic energy that reaches earth from the sun is called
Insolation
On which two dates could all locations on earth have equal hours of day and night?
March 21 and September 23
