Answer:
The laws of physics are the same for all observers in any inertial frame of reference relative to one another (principle of relativity). The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source.
Because temperature and pressure are directly proportional.
The lower you go in altitude, the less pressure there is in the Earth's atmosphere. As a result, as the gas in the atmosphere rises, it experiences less pressure, causing it to expand. When a gas expands, it produces energy. And if it's working, it's wasting energy; and if it's wasting energy, its temperature must fall, because temperature is defined as the average energy of the particles. As a result, if the particles' energy is lower, the temperature must be lower. That's why the temperature appears to drop with altitude.
