WebThe main cloud deck is formed of three layers. All of them are quite tenuous—an observer in even the densest cloud regions would be able to see objects at distances of several kilometres. The opacity of the clouds varies rapidly with space and time, which suggests a high level of meteorologic activity. WebIt might be surprising to find out that the three main greenhouse gases – carbon dioxide, methane and nitrous oxide – comprise just a tiny fraction of Earth’s atmospheric gases. … WebMar 31, 2024 · Greenhouse gases are gases in Earth’s atmosphere that trap heat.
