Trace gas causes its strong absorption of infrared radiation. Below is a table of some of the major greenhouse gases with man-made sources and their contribution to the enhanced greenhouse effect. Key Greenhouse Gases and Sources In contrast, the most abundant gases in the atmosphere are not greenhouse gases. The main reasons is because they cannot absorb infrared radiation as they do not have vibrations with a dipole moment. For instance, the triple bonds of atmospheric dinitrogen make for a highly symmetric molecule that is very inert in the atmosphere. The residence time of a trace gas depends on the abundance and
Most common words in Spanish (CREA), a text corpus compiled by the Real Academia Española (RAE). The RAE is Spain's official institution for documenting, planning, and standardising the Spanish language. A "word form" is any of the grammatical variations of a word. The second table is a list of 100 most common lemmas found in a text corpus compiled by Mark Davies and other language researchers at Brigham Young University in the United States. A "lemma" is the primary form of a word—the one that would appear in a dictionary. The Spanish infinitive "tener" ("to have") is a lemma, while "tiene" ("has")—which is a conjugation
