Web6. 1-3 The trace gases present in the earth's almosphere Answer: The remaining 0.1% of the atmosphere consists of the trace constituents. These include water vapor, carbon dioxide, ozone, methane, various oxides of nitrogen, neon, and helium. They are called trace gases because they exist in small amounts. Explanation: Pa brainles po God bless WebArgon makes up about 1% of the atmosphere and comes mostly from the decay of potassium in the Earth’s crust. It is an inert gas, which means that it does not react with other chemicals. Water Vapor. Water is cycled through all of Earth’s systems in each of its three phases: solid, liquid, or gas. Water vapor in the atmosphere is a ...
