This map shows location of 52 cities. Draw isotherms at 5° intervals, beginning with the 0° isotherm in the upper right corner.

Use the chart to plot the points on the graph to determine and select the correct graph from the options below (1-4):

Does the density of the atmosphere increase or decrease with increasing altitude?

Fill in the blanks to answer the following question most accurately: Explain on a molecular level why temperatures increase in the Stratosphere as altitude increases?

_________absorbs and becomes energized by UV radiation which increases molecular movement, increasing_________.

Fill in the blanks to answer the following question most accurately: Explain on a molecular level why temperatures increase in the Thermosphere?

The closer the molecules are to the_____________, the more radiation they absorb; this causes___________molecular movement and increases temperature.

Why doesn't it feel hot in the Thermosphere?

Fill in the blanks to answer the following question most accurately: Explain in detail, on a molecular level, how CFC's are impacting the ozone layer.

As more CFC's get released into the atmosphere, they continue to get broken down by________- this causes the________to get liberated. This liberated molecule interacts with O3, breaking it into O and O2, effectively thinning the ozone layer.

Identify which of the following lines (A, B, C) best illustrate the data points for the altitude of the noon Sun on the 22nd day of each month.

(a) Which of the three latitudes would receive the highest and the lowest insolation on 6/22? (Highest first)

(b) Which of the three latitudes would receive the highest and lowest insolation on 12/22? (Highest first)

Identify which of the following lines (A, B, C) best illustrate the data points for the average daily insolation at the top is the atmosphere (in W/m2) for the 22nd day of each month.

(a) During a year, which of the three latitudes experiences the least variation in average daily insolation at the top of the atmosphere?

(b) During a year which of the three latitudes experiences the greatest variation in average daily insolation at the top of the atmosphere?

(a) In which month does the top of the atmosphere at 45°N receive its highest average daily insolation?

In the same month, does the top of the atmosphere at the equator receive higher or lower average daily insolation than at 45°N?

During the year, at the top of the atmosphere the equator experiences two periods (six months apart) of maximum average daily insolation and two periods (six months apart) of minimum average daily insolation.

(a) When do the two maximums occur?

During the year, at the top of the atmosphere the equator experiences two periods (six months apart) of maximum average daily insolation and two periods (six months apart) of minimum average daily insolation.

(b) When do the two minimums occur?
