Atmospheric composition and stability

Question 1

How does temperature change with altitude?

Answer 1

For every 1,000 ft in altitude gained, temperature decrease 2 degrees Celsius.

Question 2

How does pressure change with temperature?

Answer 2

Pressure decreases 1 inch every 1,000 ft of altitude gained.

Question 3

Stability of the atmosphere?

Answer 3

• depends on the ability for it to resist vertical motion
• a stable atmosphere makes vertical movement difficult
• instability can lead to significant turbulence, clouds with vertical movement, and severe weather.
