Part A
Carefully look at the relationship between altitude and temperature in the atmosphere. Describe how temperature changes when moving from sea level upward in the atmosphere.



Answer :

To describe how temperature changes when moving from sea level upward in the atmosphere, we will analyze the given data and describe the observed trend in temperature with increasing altitude. Here is a step-by-step description of the temperature changes:

1. From 5,000 meters to 10,000 meters:
- At 5,000 meters, the temperature is -17.47 °C.
- At 6,000 meters, the temperature drops to -23.96 °C. The temperature decreases by 6.49 °C.
- At 7,000 meters, the temperature further drops to -30.45 °C, a decrease of 6.49 °C.
- At 8,000 meters, the temperature continues to drop to -36.94 °C, another decrease of 6.49 °C.
- At 9,000 meters, the temperature decreases to -43.42 °C, a decrease of 6.48 °C.
- Finally, at 10,000 meters, the temperature decreases to -49.90 °C, a decrease of 6.48 °C.

Observation: In this range, the temperature decreases almost linearly, with an average drop of approximately 6.49 °C per 1,000 meters.

2. From 10,000 meters to 20,000 meters:
- At 15,000 meters, the temperature is -56.50 °C. The temperature drops by 6.60 °C from 10,000 to 15,000 meters.
- At 20,000 meters, the temperature remains constant at -56.50 °C, with no change in temperature.

Observation: There is a significant drop from 10,000 to 15,000 meters, followed by a stabilization where the temperature remains constant at -56.50 °C from 15,000 to 20,000 meters.

3. From 20,000 meters to 30,000 meters:
- At 25,000 meters, the temperature increases to -51.60 °C, an increase of 4.90 °C.
- At 30,000 meters, the temperature rises to -46.64 °C, an increase of 4.96 °C.

Observation: In this range, the temperature starts to increase as the altitude increases. The increase is approximately 4.93 °C per 5,000 meters.

4. From 30,000 meters to 50,000 meters:
- At 40,000 meters, the temperature sharply rises to -22.80 °C, an increase of 23.84 °C.
- At 50,000 meters, the temperature increases further to -2.50 °C, an increase of 20.30 °C.

Observation: There is a significant increase in temperature in this altitude range. The temperature increases by approximately 22.07 °C per 10,000 meters.

5. From 50,000 meters to 80,000 meters:
- At 60,000 meters, the temperature decreases to -26.13 °C, a decrease of 23.63 °C.
- At 70,000 meters, the temperature drops further to -53.57 °C, a decrease of 27.44 °C.
- Finally, at 80,000 meters, the temperature falls to -74.51 °C, a decrease of 20.94 °C.

Observation: This range shows a dramatic decrease in temperature again, with an average drop of approximately 24.00 °C per 10,000 meters.

Conclusion:
- From sea level up to 10,000 meters, the temperature decreases steadily.
- Between 10,000 to 20,000 meters, the temperature initially drops then stabilizes.
- From 20,000 to 30,000 meters, the temperature begins to increase.
- From 30,000 to 50,000 meters, there is a significant rise in temperature.
- Beyond 50,000 meters up to 80,000 meters, the temperature drops sharply again.

The temperature changes in the atmosphere exhibit varying trends at different altitude ranges.
