Precipitation, Evaporation and Condensation.

less denser
Air pressure is caused by the weight of the atmosphere above an object. When one goes higher, there is less air above and so the pressure drops.
All of them.

Small meteors may burn up as they travel through the atmosphere, but larger ones do get through the atmosphere and land on the surface of the Earth.
One cannot hear sound on an asteroid since it has no atmosphere, but sound can travel though an asteroid's surface.
less denser
If you travel some 12. 5 miles into the sky, you will leave roughly 99 percent of the atmosphere behind. At 30 miles up, the density of the atmosphere is roughly one million times less than at the surface.
It gets colder as you travel up in the atmosphere.

Sound would travel in the moon's atmosphere if the moon had any atmosphere, but since it hasn't, it doesn't.
In summer the suns rays travel directly to the surface at a steep angle, so are still warm. In winter the rays strike at a shallower angle, and cool down rapidly as they travel a longer distance through the atmosphere before reaching the surface.
surface waves can only travel along the surface.
Sound can travel in the solid rocks of the moon but sound can not travel on the surface of the moon because there is no air for the sound to travel in.
The planet Mercury does not have an atmosphere in the same way that the Earth has an atmosphere; it has only a very thin layer of gases far above its surface. Because sound cannot travel in a vacuum, there would be no speed of sound on Mercury.
