1. On Paper

2. Hot-air balloons are a fun way to travel around the globe. (5 points)

A. In what layer can a hot-air balloon travel? (2 points)
Stratosphere
B. Why can't a hot-air balloon go to higher layers? (3 points)
As they go higher in the atmosphere, the air becomes cooler







3. The Concorde jet was a supersonic plane created in 1976 to speed transportation across the ocean. It traveled at twice the speed of sound, shortening a normal seven- to eight-hour transatlantic trip to three and a half hours. However, the Concorde still had to fly in the same atmospheric conditions as every other plane. Given this information, answer the following questions (15 points):

A. In which layer of the atmosphere did the Concorde cruise? (5 points)
Stratosphere
B. What are the characteristics of this layer that make it the ideal layer for the Concorde to travel? (5 points)
The temperature increases with weight
C. Why wouldn't it travel higher? (3 points)
It will most likely burn up
D. Why wouldn't it travel lower? (2 points)
the troposphere wouldn't carry the Concorde. The Concorde would hit buildings and other things flying so low







4. For humans to travel safely into space, we have developed high-tech space shuttles. (10 points)

A. What are two characteristics of the thermosphere that make it necessary for us to use a space shuttle to get through it? (6 points)
Heat and Gravity
B. What happens when a space shuttle reenters the atmosphere? (4 points)
It becomes very hot and will probably burn up







5. The mesosphere is found at 50 to 85 km above Earth’s surface. (5 points)

A. What temperatures would you expect in the mesosphere? (3 points)
-90 Degrees Celsius
B. What type of clothing would you need to wear if you could visit the mesosphere? (2 points)
Winter clothing








6. Water is one of the most important molecules on Earth. (5 points)

A. Which layer of the atmosphere contains 90 percent of Earth's water vapor? (3 points)
Troposhere
B. What two characteristics of this layer make it possible to retain this much water vapor? (2 points)
Gravity and Oxygen
