Answer 1

a)

The Earth's atmosphere consists, from the ground up, of the troposphere (which includes the planetary boundary layer or peplosphere as lowest layer), stratosphere, mesosphere, ionosphere (or thermosphere), exosphere and the magnetosphere. Each of the layers has a different lapse rate, defining the rate of change in temperature with height.

Answer 2

I suggest you look at the Wikipedia article for "atmosphere". The purpose of these boards is to help people understand things, not provide the answers to random trivia questions.
