MET1010 TEST 1 STUDY GUIDE 1 A south wind Blows from the south 2 A towering cloud or cluster of clouds accompanied by thunder lightning and strong gusty winds is a Anticyclone 3 Almost all of the earth s weather occurs in the Troposphere 4 Areas of high atmospheric pressure are also known as Anticyclones 5 As a radiosonde balloon ascends through the atmosphere the balloon Burst 6 At night when the weather is extremely cold and dry Atmospheric pressure decreases with increasing attitude 7 At the 500 mb level the amount of oxygen inhaled in a single breath is of that inhaled at sea level About one half 8 Clouds often form in the Troposphere 9 Condensation is more likely to occur When the air cools 10 Generally weather in the middle latitudes tends to move from to West east 11 If you were to take a breath of pure oxygen from a tank you d be getting about the amount of oxygen you d get by taking a normal breath of our atmosphere Five times 12 In a temperature inversion Air temperature increases with increasing height 13 In a volume of air near the earth s surface occupies 78 percent and nearly 21 percent Nitrogen oxygen 14 In the atmosphere tiny solid or liquid suspended particles of various composition are called aerosols 15 In the middle latitudes of the Northern Hemisphere surface winds tend to blow and around an area of surface low pressure Counterclockwise inward 16 In the middle latitudes of the Northern Hemisphere surface winds tend to blow and around an area of surface high pressure Clockwise and outward 17 In the stratosphere the air temperature normally Increases with increasing height 18 Meteorology is the study of The study of the atmosphere and its phenomena 19 Most of the ionosphere is found in what atmospheric layer Thermosphere 20 Much of Tibet lies at altitudes over 18 000 feet where the pressure is about 500 mb At such altitudes the Tibetans are above roughly 50 percent of the air molecules in the atmosphere 21 On a weather map sharp changes in temperature humidity and wind direction are marked by Front 22 Ozone in the stratosphere Protects life from harmful ultraviolet radiation 23 Since the turn of this century CO2 in the atmosphere has Been increasing in concentration 24 The amount of force exerted over an area of surface is called Pressure 25 The atmospheric layer in which we live is called the Troposphere 26 The difference in altitude i e the thickness is greatest in the layer bounded by 1mb and 10mb 27 The earth s atmosphere is divided into layers based on the vertical profile of Air temperature 28 The electrified region of the upper atmosphere is called the Ionosphere 29 The gas responsible for the greenhouse effect on Venus is Carbon dioxide CO2 30 The gas that absorbs most of the harmful ultraviolet radiation in the stratosphere is Ozone 31 The gas that shows the most variation from place to place and from time to time in the lower atmosphere is which of the following Carbon dioxide CO2 32 The greenhouse gas that has been increasing in concentration at least partly due to deforestation is Carbon dioxide CO2 33 The hottest atmospheric layer is the Thermosphere 34 The instrument that measures temperature pressure and humidity at various altitudes in the atmosphere is the Radiosonde 35 The ionosphere is an atmospheric layer that contains a high concentration of ions An ion is An atom or molecule that has lost or gained an electron 36 The most abundant gases in the earth s atmosphere by volume are Nitrogen and oxygen 37 The most abundant greenhouse gas in the earth s atmosphere is Water vapor H2O 38 The number or mass of air molecules in a given space or volume is called Density 39 The only substance near the earth s surface that is found naturally in the atmosphere as a solid liquid and a gas is Water 40 The primary source of oxygen for the earth s atmosphere during the past half billion years or so appears to be Photosynthesis 41 The rate at which temperature decreases with increasing altitude is known as the Lapse rate 42 The temperature of the tropopause Is much colder than the temperature at the earth s surface 43 The wind direction is The direction from which the wind is blowing 44 There is a lot of mixing and overturning of air in which of the following atmospheric layers Troposphere 45 Typically water vapor occupies about what percentage of the air s volume near the earth s surface Less than 4 percent 46 Warming in the stratosphere is mainly caused by absorption of ultraviolet radiation by ozone 47 Where cold surface air replaces warm air the boundary separating the different bodies of air is A cold front 48 Which latitude belt best describes the middle latitudes 30o to 50o 49 Which of the following are NOT units of pressure Newtons 50 Which of the following equations is correct Weight mass X gravity 51 Which of the following is MOST likely associated with fair weather High pressure are 52 Which of the following is considered a variable gas in the earth s atmosphere Water vapor 53 Which of the following processes remove CO2 from the atmosphere Photosynthesis 54 Which of the following weather elements ALWAYS decreases as we climb upward in the atmosphere Pressure 55 holds a planet s atmosphere close to its surface Gravity 56 A good absorber of a given wavelength of radiation is also a good emitter of that wavelength This is a statement of Kirchhoff s law 57 A change of one degree on the Celsius scale is a change of one degree on the Fahrenheit scale Larger than 58 A red shirt Selectively scatters red wavelengths of visible light and absorbs the rest 59 According to Wein s displacement law the wavelength at which maximum radiation occurs Is inversely proportional to the temperature 60 An increase in albedo would be accompanied by in radiative equilibrium temperature A decrease 61 Charged particles from the sun that travel through space at high speeds are called Solar flares 62 Clouds infrared radiation and visible radiation Absorb reflect 63 Electromagnetic radiation with wavelengths between 0 4 and 0 7 micrometers is called Visible light 64 Energy of motion is also known as Kinetic energy 65 Evaporation is a process cooling 66 Heat is energy in the process of being transferred from Hot objects to cold objects 67 How do red and blue light differ Red has a higher wavelength and lower frequency blue has a lower wavelength 68 How much radiant energy will an object emit if its temperature is at absolute zero none 69 If the amount of energy lost by the earth
