EATS 1011 3.0 Introduction to Atmospheric Science 1. Condensation trails that form from aircraft exhaust high in the troposphere a. consist of smoke particles formed by the mixing of the aircraft exhaust and the upper air. b. consist of condensed water vapour due to the mixing of two air masses with very different temperatures but similar relative humidities . c. consist of nitrogen oxide particles spewed out from the exhaust. d. are formed from the unburnt fuel freezing in the cold upper troposphere. e. are formed when the aircraft flies through a cloud. 2. The Earth/atmosphere/ocean system has an average albedo of 30%. a. This means that that 70% of the energy incident on the Earth is absorbed in the surface and atmosphere. b. This means that that 30% of the energy incident on the Earth is reflected back to space. c. The Earth’s albedo is smaller than that of Venus. d. Clouds make up a large fraction of the reflectivity. e. All of the above are true. 3. The saturation vapour pressure of H 2 O a. is only a function of temperature. b. is the pressure of the vapour in equilibrium with a plane water liquid surface. c. is equal to atmospheric pressure when water boils. d. increases with temperature. e. all of the above are correct. 4. The greenhouse effect a. concerns the warming of the atmosphere and surface due to IR active gases. b.
