Atmosphere & Water Cycle

The Water CycleNational Science Foundation Water Cycle Matching Connect the term to the best description.(Tip: If you can't see all the terms at once, you can try dragging the line to a random option in the opposite column and then scroll your page up or down. Then go back and grab the end of the line to drag it to the correct answer.) Transpiration process of vapor being given off by plants Condensation phase change of water vapor to a liquid Evaporation phase change of liquid water to a gas Water Cycle Repeated patter of water moving between the Earth and the atmosphere Precipitation Water falling from sky to the Earth Hydrosphere All the water on Earth Runoff Precipitation that is not absorbed by the soil and flows into rivers, lakes, and the ocean Use the drop down menu to select the appropriate word to complete the sentence. In the water cycle, there is no beginning or end to the flow of water. It is simply transferred from one form or location to another. The amount of water on Earth has stayed the same for eons. There are two types of water on Earth: freshwater and saltwater. Most water on Earth is saltwater. Most of Earth's freshwater is locked up in glaciers or ice caps; the second greatest abundance of freshwater is located underground. What Makes Humidity Feel So Hot? How hot a day feels is largely dependent upon the atmosphere's Dew point Absolute humidity Relative humidity Air temperature Matching Pair the term with its definition. Humidity Amount of water vapor in the air Capacity Amount of water something can hold Saturated Air Holds all the water it possibly can at a given temperature (can't hold anymore) Specific Humidity Actual amount of water vapor in the air Relative Humidity Amount of water vapor in the air compared to its capacity Sling psychrometer Instrument used to measure relative humidity Sling Psychrometer Demonstration Use the relative humidity chart to respond to the questions in the next sections. Relative Humidity The sling psychrometeris the tool used to measure relative humidity. The wet bulb will get cooler when spun because of the process of evaporation. When the wet-bulb depression is 0, that means the air is saturated and the relative humidity is 100%. If the dry bulb measures 20C and the wet bulb measures 18C, the wet-bulb depression is 2and the relative humidity is 83%.
