Question

Thermosphere Between about 53 miles (85 km) and 375 miles (600 375m km) lies the thermosphere. This layer is known as the upper atmosphere. While still extremely thin, the gases of the thermosphere become increasingly denser as one descends toward the earth. 600km As such, incoming high energy ultraviolet and x-ray radiation from the sun begins to be absorbed by the molecules in this layer and causes a large temperature increase. 160km 00m Because of this absorption, the temperature increases with height. From as low as-184°F (-120°C) at the bottom of this layer, temperatures can reach as high as 3,600 F (2,000 °C) near the top. 140km 75m 20km However, despite the high temperature, this layer of the atmosphere would still feel very cold to our skin due to the very thin atmosphere. The high temperature indicates the amount of the energy absorbed by the molecules but with so few in this layer, the total number of molecules is not enough to heat our skin. 100km 50m 80km Exosphere This is the outermost layer of the atmosphere. It extends from the top of the thermosphere to 6,200 miles (10,000 km) above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth. At the bottom of the exosphere is the thermopause located around 375 miles (600 km) above the earth (NOAA) 60km 25m 40km 8Tor F: If you follow the temperature line in the graph above from the surface of the Earth to the top of the atmosphere, moving to your left represents a decrease in temperature, to your right represents an increase in temperature, and straight up represents a constant 20km temperature.

Explanation / Answer

8.True. Explanation: Refering the graph it can be seen that the temperature decreases to the left and increases to the right. 9.true explanation: temperature rises from -20 degree to 40degree. 10.true. Explanation: temperature decreases from 20 to -20. 11. True. Explanation: It is increasing and decreasing within different altitudes.
