[EX Q]: Water is a simple chemical compound. Each molecule of water contains two hydrogen atoms (H2 ) and one oxygen atom (O). Thats why the chemical formula for water is H2 O. If water is so simple, why is it special? Water is one of the few substances that exists on Earth in all three states of matter. Water occurs as a gas, a liquid and a solid. You drink liquid water and use it to shower. You breathe gaseous water vapor in the air. You may go ice skating on a pond covered with solid water ice in the winter. Earth is often called the water planet. Figure 13.1 shows why. If astronauts see Earth from space, this is how it looks. Notice how blue the planet appears. Thats because oceans cover much of Earths surface. Water is also found in the clouds that rise above the planet. Most of Earths water is salt water in the oceans. As Figure 13.2 shows, only 3 percent of Earths water is fresh. Freshwater is water that contains little or no dissolved salt. Most freshwater is frozen in ice caps and glaciers. Glaciers cover the peaks of some tall mountains. For example, the Cascades Mountains in North America and the Alps Mountains in Europe are capped with ice. Ice caps cover vast areas of Antarctica and Greenland. Chunks of ice frequently break off ice caps. They form icebergs that float in the oceans. Did you ever wonder where the water in your glass came from or where its been? The next time you take a drink of water, think about this. Each water molecule has probably been around for billions of years. Thats because Earths water is constantly recycled. Water is recycled through the water cycle. The water cycle is the movement of water through the oceans, atmo- sphere, land, and living things. The water cycle is powered by energy from the Sun. Figure 13.3 diagrams the water cycle. Water keeps changing state as it goes through the water cycle. This means that it can be a solid, liquid, or gas. How does water change state? How does it keep moving through the cycle? As Figure 13.3 shows, several processes are involved. Evaporation changes liquid water to water vapor. Energy from the Sun causes water to evaporate. Most evaporation is from the oceans because they cover so much area. The water vapor rises into the atmosphere. Transpiration is like evaporation because it changes liquid water to water vapor. In transpiration, plants release water vapor through their leaves. This water vapor rises into the atmosphere. Condensation changes water vapor to liquid water. As air rises higher into the atmosphere, it cools. Cool air can hold less water vapor than warm air. So some of the water vapor condenses into water droplets. Water droplets may form clouds. Precipitation is water that falls from clouds to Earths surface. Water droplets in clouds fall to Earth when they become too large to stay aloft. The water falls as rain if the air is warm. If the air is cold, the water may freeze and fall as snow, sleet, or hail. Most precipitation falls into the oceans. Some falls on land. Runoff is precipitation that flows over the surface of the land. This water may travel to a river, lake, or ocean. Runoff may pick up fertilizer and other pollutants and deliver them to the water body where it ends up. In this way, runoff may pollute bodies of water. Infiltration is the process by which water soaks into the ground. Some of the water may seep deep under- ground. Some may stay in the soil, where plants can absorb it with their roots. In all these ways, water keeps cycling. The water cycle repeats over and over again. Who knows? Maybe a water molecule that you drink today once quenched the thirst of a dinosaur.

[EX Q]: C.D. "Charlie" Bales, the fire chief of the small American ski town of Nelson, Washington, is intelligent, humorous, charismatic, athletic and skilled. Bales is sensitive about his large nose, which many in town have learned to not mention. He is unable to have it surgically altered because of a dangerous allergy to anesthetics. He is close to many in town, especially his godsister, Dixie, who owns the town diner and several rental homes. He becomes immediately attracted to beautiful newcomer Roxanne Kowalski, an astronomy student renting from Dixie while searching for a new comet. She adores Bales, but only as a friend, preferring Chris, a handsome but dim fireman. Roxanne goes to Bales for help when Chris fails to advance their relationship further than curious glances. Through a turn of events, she falsely believes Chris is deeply intelligent. When Bales informs Chris of Roxanne's interest, Chris gets sick, intimidated by intelligent women. Chris starts to write her a letter, but takes all day with little result. He convinces Bales to write the letter, with prose that soon bowls over Roxanne. When informed that Roxanne wants to meet him, Chris again gets sick and refuses to meet until Bales comes up with a plan to allow him to be as brilliant as his letter makes him appear. Chris arrives at Roxanne's house with a hunter's cap on, hiding the earphones that relay Bales' words. When the equipment fails, Chris bungles the meeting by speaking his own crass thoughts. After Roxanne storms back into the house furious, Chris begs Bales to fix his mess again. At first he repeats what he is told from under a tree beneath Roxanne's window, but soon also ruins that. Then they switch jackets and hats so Bales can speak the words as Chris. They achieve their goal, and she invites Chris in to make love. Roxanne gets word about the comet and has to go out of town for a week. Since she can't find Chris, she gives Bales the address of her hotel and asks him to tell Chris to write to her. Bales writes her several times a day, each letter more incredible than the last. They affect Roxanne so deeply that she returns early. Bales is writing a new letter to her in Dixie's diner when he finds out that Chris (who knows nothing about the letters) is on his way to see Roxanne. He arrives at her home and warns Chris that Roxanne would be mentioning some letters that he supposedly wrote. She tries to get Chris to be the man in the letters, revealing that his looks are only secondary to her. Knowing that his looks are all he has, Chris runs out, leaving her confused. Dixie puts the last letter under her door and after reading it, Roxanne calls Bales over. Chris prepares to leave town with a bartender, Sandy, whom he met while Roxanne was away. When she asks if he has told Roxanne (the women are acquaintances), he replies that he will write her a letter since he has a history of it. Bales arrives, unaware that Roxanne knows the truth. She asks him to read one of the letters and then to look at the back, which shows that Dixie revealed its true author. She explodes in anger that he lied to her. He retorts that he simply wanted to tell her how he felt about her, but she was only interested in Chris's face and body. When he reminds her that it only took a few nice words for Chris to get her into bed, she punches him in the face and throws him out. As he prepares to say more he stops and sniffs the air. He slowly walks back to the firehouse and alerts his team, who then "follow his nose" until they find and extinguish the fire. During their celebration afterwards, someone mentions his nose and although everyone thinks he will get upset, he doesn't. Back home, sitting on his roof, Bales hears someone speaking his words to him. It's Roxanne, declaring that she realizes that it was everything from Bales that she loved, not Chris'
