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 Output:
water that falls from clouds to Earths surface


Ex Input:
Woody lives in a slum on the edge of the city, and is exasperated at his bills. He wishes aloud that he were rich. At that moment, a four-leaf clover appears in the floorboards. Woody takes it, hoping it will bring him good luck. To his surprise, it transforms into a leprechaun woodpecker. Speaking with an Irish brogue, it names itself as O'Toole, and demonstrates its seemingly endless magical abilities to Woody. It then grants him three wishes. An excited Woody immediately wishes for immense wealth.The leprechaun takes Woody to "the end of the rainbow", where Woody indeed finds himself swimming in money. He takes a bag of cash and runs out. At that moment, an alarm goes off. He turns around, and realizes he has just robbed from the First National Bank. He is immediately confronted by a police officer with an Irish brogue. While Woody attempts to deflect the blame onto the leprechaun, the police officer does not believe him. At that moment, the leprechaun woodpecker jumps in and saves Woody by bashing the officer over the head with a club.A lengthy chase ensues between the officer and Woody. The leprechaun continually helps Woody to escape from tight situations, until Woody is finally caught and handcuffed to two other officers. The leprechaun appears, and Woody tells it his second wish-- to be transported home safely. The leprechaun frees Woody, and replaces him with a skunk. The horrified officers run off down the street, trying to break away from the handcuffs without luck.Once Woody is back home, the leprechaun reminds him that "a wish is not what pays the rent", and goes to leave. However, Woody reminds the leprechaun that he still has one wish left, and angrily screams at it, "GO TO BLAZES!" The leprechaun, having no choice, jumps and plummets through the floor into Hell, where he came from. The Devil, also a woodpecker with an Irish brogue, laughs and welcomes the leprechaun back. Iris out.

What does Woody set off when he exits through the bank door?
