Pak Exam MCQs
A. 60 km
B. 85 km
C. 75 km
D. 80 km
Answer & Solution
Option: B
Explanation : Earth’s atmosphere is divided into five main layers: Exosphere, Thermo-sphere, Mesosphere, Stratosphere and Troposphere.
Mesosphere starts at 31 miles (50 km) and extends to 53 miles (85 km) high. The top of the mesosphere, called the mesopause, is the coldest part of Earth’s atmosphere, with temperatures averaging about minus 130 degrees F (minus 90 C). Jets and balloons don’t go high enough, and satellites and space shuttles orbit too high.
