Answer:
11. TRUE
12. TRUE
13. FALSE
14. TRUE
15. FALSE
Explanation:
11. True, The troposphere is the lowest layer of our atmosphere. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. We humans live in the troposphere, and nearly all weather occurs in this lowest layer.
12. True, Auroras are found in thermosphere
13. False, Located between about 50 and 80 kilometers (31 and 50 miles) above Earth's surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit)
14. True, The exosphere is the most distant atmospheric region from Earth's surface.
15. False, In the mesosphere, temperature decreases as altitude increases, to as low as −93°C.
