"The Earth's atmosphere is like an obstacle course for incoming solar radiation. About 30% of it is reflected away by the atmosphere, clouds, and surface."
"In summary, the Earth's atmosphere is like a very thin blanket in which the sun's rays pass through at different angles."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
