I think it's because of gravity.
Yes, the speed of sound does change with altitude. In general, the speed of sound increases with higher altitudes due to the decrease in air density.
The speed of sound increases with altitude due to the decrease in air density. This means that at very high altitudes, where air density is lower, the speed of sound will be faster compared to at sea level.
Wind speed generally increases with altitude. This is due to a decrease in surface friction and obstacles that slow down the wind closer to the ground. As air is less hindered by obstacles at higher altitudes, it can flow more freely and result in higher wind speeds.
Decrease
As altitude increases, air density decreases. This reduction in air density leads to lower aerodynamic drag on an aircraft, allowing it to achieve a higher stall speed (Vs) at higher altitudes. Therefore, Vs increases with altitude due to the decrease in air density.
Temperature decreases with altitude in the mesosphere due to the decrease in atmospheric pressure with height. This is because the mesosphere is above the stratosphere where the ozone layer absorbs incoming solar radiation, leading to a decrease in temperature as altitude increases.
The characteristics of altitude include a marked decrease in temperature along with a decrease in available oxygen. Altitude also offers increased amounts of snow and wind.
1,700-foot decrease.
You must buy a bicycle computer and attach it to your bike. They can calculate various things- speed, distance, RPM, time, tempertature, altitude, speed increase or decrease
Temperature will decrease as the altitude increases at all levels due to the thinning of atmospheric gasses.
Temperature will decrease as the altitude increases at all levels due to the thinning of atmospheric gasses.
As you go higher in altitude, the air becomes less dense, meaning there are fewer air molecules above you exerting pressure. This decrease in air density leads to a decrease in atmospheric pressure as you ascend in altitude on Earth.
