Explain why the top of the mesosphere is colder than the top of the troposphere?
Think about the characteristics of both of these layers to decide. Use the words density and air pressure in your explanation.
Make the distinction that the particles are far apart in the mesosphere so they can’t transfer energy – question 15 on quiz – not fewer gasses but spread out
