Answer to Question 2
In the most basic of terms, the greenhouse effect refers to the differential transmissivity of shortwave insolation and longwave terrestrial radiation. In other words, certain atmospheric gases and particulates are transparent to incoming radiation, but opaque to outgoing terrestrial radiation. As a result, this outgoing radiation is absorbed and reradiated to Earth's surface. However, the analogy to a greenhouse is not quite correct because the atmosphere doesn't trap the longwave radiation in the manner a greenhouse does. Rather, the passage of longwave radiation to space is delayed.
