    1. Vertical structure of the atmosphere Introduction to Meteorology Leila Carvalho

    2. Where is the upper boundary of the atmosphere?

    3. Well… There is no definite answer to this question. What happens is that air becomes thinner at higher altitudes. At an altitude of 16 km (10mi) the density of the air is only about 10% of that at the sea level and at 50km is only about 1% of that at the sea level At 100km (60mi) 99.99997 % of the atmosphere is below this height Most of the “action” or the “weather” that affects surface occurs below ~ 12km, the region we call ‘troposphere’ ( Greek "tropos" for "turning" or "mixing“)

    4. How can we explain these differences in density ? Answer: GRAVITY FORCE!
