Diffraction of a wave depends on wave and speed
The speed of sound is slower at higher altitudes because the air temperature is lower. The greater the amplitude, the louder the sound. It is your perception of the energy of a sound. What two factors affect the loudness of a sound
Speed of Sound and frequency
Speed and direction.
The two things that affect the gravitational force is Mass and Distance.
Diffraction of a wave depends on wave and speed
speed = distance / time, that's the most basic formula that uses two things to get value for speed

The 2 things are speed and distance.
force and speed
Speed of Sound and frequency
Too light and too close to the 1/6 rule in escape speed from earth's gravity. A gas must be withing 1/6 of the escape speed from earth's escape speed for it's gravity to be easily retained in the earth's atmosphere. These two gases are heated too easily. are too light and too close to the escape speed to hang around unfixed, or untrapped in the atmosphere.
