What is the "greenhouse effect" as applied to Earth's atmosphere? How is Earth similar and different than a greenhouse?
What will be an ideal response?
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.
