Name: ______________________________ Date: ____________ Study Guide: Chapters 17 & 18 – Atmosphere & Clouds Circle or Underline the correct choice. What gas makes up 78% of our atmosphere? – hydrogen, nitrogen or oxygen What type of cloud develops or moves vertically? – cumuliform or stratiform What type of heat energy can travel through the emptiness of space? – conduction, convection, or radiation What process provided earth’s early atmosphere with free oxygen? - cellular respiration or photosynthesis During what time of year is the angle of insolation near 90 o in Fleetwood? – summer or winter What instrument is used to measure relative humidity? – anemometer, barometer, or psychrometer What prefix is given to clouds that form in the middle altitudes (2000-7000m)? Alto, cirro, or strato What is the state of matter of water at 15oC? – solid, liquid or gas Which has the ability to hold more water vapor? – cold air or warm air What is it called when water changes from a liquid state to a gaseous state? – condensation, evaporation, or sublimation What type of fog occurs as moist, warm air circulates above a cold surface? advection fog or radiation fog What is created by freezing dew? – freezing rain, frost, or sleet What heat transfer method explains why hot air rises and cool air sinks? – conduction, convection, or radiation What compounds are taken in by plants during photosynthesis and given off by animals during cellular respiration? carbon dioxide & glucose carbon dioxide & water oxygen & glucose oxygen & water What are solid particles in the atmosphere that water vapor condenses on to form clouds? – vaporizers, attractants, or condensation nuclei Is this statement True or False? True or False The tropopause occurs at higher altitudes near the equator. True or False The United States did not sign the Kyoto Protocol, an international agreement for the reduction of greenhouse gas emissions. True or False More rain will fall on the cooler, windward side of a mountain. True or False Dry air cools at a slower rate than humid air. True or False Air temperature in the thermosphere decreases with altitude. Will this property reflect (R) or absorb (A) more solar radiation? _____ Plants _____ Carbon Dioxide _____ Volcanic Ash _____ Polar Ice _____ Greenhouse Gases _____ Water Vapor _____ Clouds _____ Ozone Match each cloud with its description. ______ cirrus A. low, layered clouds ______ cumulus B. fluffy clouds with flat bases ______ nimbus C. high, feathery clouds ______ stratus D. dark, rain clouds Assign a layer of the atmosphere to each of the following facts. Mesosphere (M), Stratosphere (S), Thermosphere (TH), Troposphere (TR) _____ Nearest the surface: 0-12 km _____ ozone layer _____ Clear, dry layer: 12-40 km _____ auroras _____ Second highest layer: 40-80 km _____ weather events _____ Highest layer of different gases: 80-120 km _____ ionosphere _____ Most of the Earth’s water vapor _____ highest density Match each form of pollution with its description. _____ Acid Rain A. airborne sulfur dioxide mixed with water _____ Air pollution B. protective region damaged by CFC’s from aerosols _____ Global warming C. gas concentration high enough to harm humans _____ Ozone layer D. ground level ozone produced by car exhaust _____ Smog E. the effect of fossil fuel usage on Earth’s climate Match each frozen form of precipitation with its description. ______ frozen raindrops that fall in summer A. drizzle ______ rain that freezes on the earth’s surface B. freezing rain ______ rain that freezes while falling C. hail ______ fine drops of rain that fall slowly D. sleet Explain the difference between heat and temperature. Explain why water warms and cools more slowly than land.
