4 The Water Cycle Interactive USGS water cycle interactive - Hover over the keyword and answer the following questions. CONDENSATION: Condensation is the process by which water vapor is changed into what? Why does condensation happen? Does cold air or warm air contain more water vapor? PRECIPITATION: What does water vapor become in the upper atmosphere? When cloud droplets become heavier what types of precipitation will occur? Is precipitation necessary for the water cycle? EVAPORATION: Evaporation is the process by which water changes from what to what? Where is this water vapor (gas)? What is necessary for evaporation to occur? Does evaporation occur faster in warm or cold conditions? SUN : What does the sun have to do with the water cycle? Name two ways that the sun makes a difference in the water cycle RUNOFF: GROUNDWATER FLOW : What is surface runoff? Why is runoff important? TRANSPIRATION (EVAPORATION AND TRANSPIRATION) : Give an example of transportation Why is transpiration important to the water cycle? 4

5 ICE AND SNOW : How are ice and glaciers an important part of the water cycle? What percentage of freshwater is locked up in ice, snow and glaciers? OCEANS : What percent of water does the ocean hold? Why is the ocean one of the most important parts of the water cycle? ATMOSPHERE : What is the air in the atmosphere made up of? What does the water vapor miles high in the atmosphere form? RIVERS : How does the water get to the rivers? Why are rivers important to the water cycle? GROUNDWATER FLOW : What does infiltration mean? How does the water get underground? Now click on the advanced in the upper right corner and answer the following: WATER DROP : Where is 96% of the water found? What is the percentage of fresh water? CLOUDS : What are clouds made of? How does water vapor move? PLANT UPTAKE : How does water leave a leaf? 5

6 Water Cycle Notes Definition o The continuous movement of water above and below earth's surface o Movement is driven by the sun and gravity Importance o Responsible for climate changes o Provides water to all aspects of life (plants, animals, humans) Earth's Water Breakdown o 97.5% Salt Water o 2.5% Freshwater 68.7% Glaciers and icecaps 30.1% Ground Water 1.2% Surface and other freshwater Steps of Water Cycle o Evaporation / Transpiration o Condensation o Precipitation o Run Off Evaporation/Transpiration o Water moves from the ground (or in plants) to the air (water vapor) o Moves from Liquid to Gas o Driven by the Sun Condensation o Water moves from the air and forms clouds o Moves from a gas (water vapor) to a liquid (cloud droplets) o Driven by the Sun o Why are clouds important? They give us information about the wind speed and temp. They also used to be used to forecast weather This was important before we had TV s and phones o What do clouds tell us? Higher Clouds = Better weather (in general) Lower Clouds = More Precipitation (in general) Precipitation o Water moves from the air to the ground o Moves from a liquid (cloud droplets) to a liquid (larger droplets) o Driven by gravity Why is precipitation important? It provides our plants and reservoirs with water Indicates air temperature Type of precipitation varies based on air temperature Runoff o Water moves from the ground into streams, lakes, and oceans o Stays a liquid o Driven by gravity 6

7 Water Cycle Movement Background: Water covers about 75 percent of the Earth and is constantly moving. Energy from the Sun, which allows evaporation, and gravity are the driving forces that power the water cycle. The movement is greatly influenced by the contour of the land and geologic features such as mountains, valleys, and hills. While water does circulate from one state to another in the water cycle, the path it can take is variable. Procedure: 1. Pretend you are a water molecule. 2. Remove a strip of paper from the cup at your station and read it 3. Write the information in the table below o If water molecule stays in the same location you can place --- s for the part of the water cycle and what it's driven by o DO NOT GO RANDOMLY FROM STATION TO STATION 4. Put the strip back and follow the directions on the strip of paper and move to the station instructed 5. Repeat steps 1-5 until you have your entire table completed 6. Answer the analysis questions below Data: Station Description of event Part of Water Cycle (Evaporation, Condensation, Precipitation, Runoff, or ---) Driven by (Sun, Gravity, N/A, or ---) MOVE TO New Location EX 1 Cloud Falls as rain Precipitation Gravity Mountain EX 2 Mountain Roll down hill Runoff Gravity Lake

8 15. Analysis Questions: 1. What would happen if all of Earth s water stayed in the oceans? Provide 2 things 2. In the space below, draw the path YOU took as a water molecule with arrows and numbers from your table on page 6. YOUR DRAWING SHOULD LOOK DIFFERENT FROM EVERYONE ELSE!!! 8

9 Water Cycle Drawing In the space below, draw each step of the water cycle. Next to each step indicate the change in the state of matter and the process the step is driven by. 9

10 Guiding Questions 1. What forces move water through the water cycle? 2. What are the steps of the water cycle and how does water transform as it moves through it? Step of the Water Cycle Starting State of Matter (solid, liquid or gas) Ending State of Matter (solid, liquid or gas) 10
