Other gases, such as carbon dioxide, water vapor, methane, oxides of nitrogen, ozone, and ammonia, are considered trace gases. Although relatively unimportant in terms of their absolute volume, they have significant effects on the Earth's weather and climate.\n\n2. A gas found in very small amount in the atmosphere, such as water vapor, carbon dioxide, methane, and ozone. These gases while small in volume have major impacts on Earth's weather and climate.",
