WEAX 201 Module 3 Study Guide Latent heat When water changes phase, it transfers _________which play an important role in energy exchange between the ocean and atmosphere and in convective weather development. 60% Water in gas form (water vapor) is the most abundant atmospheric greenhouse gas and accounts for _____of the atmospheric greenhouse effect. Evaporation Water vapor enters the atmosphere via _______ and transpiration by plants over land. Clouds Once in the atmosphere, water vapor can condense into liquid, or deposit to ice, to form ________. Precipitation Water leaves the atmosphere via ________. Water _____exists in all three phases in the earth's atmosphere: liquid water, ice, and water vapor. Condensation Water molecules leave the water surface via evaporation, and attach to the surface via ________. Exceeds When evaporation _______condensation, the air over the water surface is unsaturated. Equals When evaporation _______condensation, the air over a water surface is saturated. Expanding or contracting The parcel's pressure always adjusts to that of the environment by___________. Unsaturated Air not at its maximum capacity for water vapor is _______ atmospheric conditions allow for water molecules to remain as a vapor. Saturated Air at its maximum capacity for water vapor is ________ atmospheric conditions do not allow water to remain in vapor form, and water molecules start to condense into liquid. Temperature Air's capacity for water vapor is highly ______ dependent. Increases As air temperature ________, water vapor molecules move faster, and are more likely to stay in vapor form and less likely to condense to liquid. Cooled Saturation (and thus condensation) becomes more likely as air is _______. Warm, cold _____ air has a greater capacity for water vapor than ______ air. More Warm air can contain ______ water vapor molecules without becoming saturated, compared to cold air. Humidity
