A star with an azimuth of 180 degrees would be due south, and an altitude of 20 degrees would place it 20 degrees above the horizon. So, the star would be in the southern part of the sky, 20 degrees above the horizon.
Earth
It takes a rocket about 15-20 minutes to reach outer space, which begins at the Kármán line located 62 miles (100 kilometers) above Earth's surface. The exact time can vary depending on the rocket's speed and trajectory.

mesosphere
The stratosphere I think
The layer of the atmosphere that extends from 10-20 kilometers above the Earth's surface is the stratosphere. This layer is characterized by the presence of the ozone layer, which plays a crucial role in absorbing and filtering out harmful ultraviolet radiation from the sun.
troposhpere
The stratosphere's upper limit is about 20 miles above sea level.
The Troposphere is nearest and extends from the surface of the earth to approximately 10 thousand metres above the surface. This explains why the air is described as being 'thin' when at the top of some of the highest mountains of the World.Hope this helps.
Stratosphere is 10 - 20 miles above earth and contains the ozone layer.
You must be 20° above (north) the equator
Parts in the eastern side are 15 feet above sea level. Parts in the western side are 20 feet above sea level. 15' = evacuation C 20' = evacuation D
The mass of air in the stratosphere is approximately 20% of the total mass of Earth's atmosphere. This layer of the atmosphere extends from about 10 to 50 kilometers above the Earth's surface. The density of air in the stratosphere decreases with increasing altitude.
Approximately 27% of Earth's land mass is above 1000 ft in elevation.
The biosphere extends from about 8 kilometers above the Earth's surface to as deep as 11 kilometers below the ocean's surface. This depth range accounts for where living organisms can be found on Earth.
