WebThe official beginning of space is 100 km above the Earth’s surface. The gases that make up the Earth’s atmosphere thin out rapidly as height increases. If you were in a rocket travelling upwards, at a height of 11 km, you would have passed 77.5% of the Earth’s atmosphere. At 31 km, you would have passed 99%. WebMay 31, 2013 · The speed of sound through air or any other gas, also known as Mach 1, can vary depending on two factors. ... the speed required to break the sound barrier decreases higher in the atmosphere, ...

WebThe lowest portion of the atmosphere is the troposphere, a layer where temperature generally decreases with height. This layer contains most of Earth’s clouds and is the location where weather primarily occurs. The lower levels of the troposphere are usually strongly influenced by Earth’s surface.
