Answer :
In the given statements:
1. False
Explanation: In the troposphere, the temperature generally decreases with altitude due to the decrease in air pressure as you move higher up, not because gases absorb little solar radiation.
2. True
Explanation: The ozone layer is indeed located in the stratosphere, not the mesosphere, and it absorbs the sun's ultraviolet radiation, playing a crucial role in protecting life on Earth from harmful UV rays.
3. False
Explanation: As altitude increases from the Earth's surface, air pressure decreases due to the decreasing density of air molecules at higher altitudes.
4. False
Explanation: It is hard to breathe in high mountains not because many molecules are present in the air but because the air pressure decreases at higher altitudes, leading to lower oxygen levels, making it harder to breathe.
5. False
Explanation: The atmosphere is divided into different layers based on temperature variation and composition, not solely on temperature. Temperature is a significant factor, but other aspects like pressure and composition also play a role in defining the layers of the atmosphere.
