[EX Q]: Context: You are on vacation at the beach. You take your flip-flops off so you can go swimming. The sand is so hot it hurts your feet. You have to run to the water. Now imagine if it were hot enough for the sand to melt. Some places inside Earth are so hot that rock melts. Melted rock inside the Earth is called magma. Magma can be hotter than 1,000C. When magma erupts onto Earths surface, it is known as lava, as Figure 3.17 shows. Minerals form when magma and lava cool. Most water on Earth, like the water in the oceans, contains elements. The elements are mixed evenly through the water. Water plus other substances makes a solution. The particles are so small that they will not come out when you filter the water. But the elements in water can form solid mineral deposits. Fresh water contains a small amount of dissolved elements. Salt water contains a lot more dissolved elements. Water can only hold a certain amount of dissolved substances. When the water evaporates, it leaves behind a solid layer of minerals, as Figure 3.18 shows. At this time, the particles come together to form minerals. These solids sink to the bottom. The amount of mineral formed is the same as the amount dissolved in the water. Seawater is salty enough for minerals to precipitate as solids. Some lakes, such as Mono Lake in California, or Utahs Great Salt Lake, can also precipitate salts. Salt easily precipitates out of water, as does calcite, as Figure 3.19 shows. The limestone towers in the figure are made mostly of the mineral calcite. The calcite was deposited in the salty and alkaline water of Mono Lake, in California. Calcium-rich spring water enters the bottom of the lake. The water bubbles up into the alkaline lake. The Underground water can be heated by magma. The hot water moves through cracks below Earths surface. Hot water can hold more dissolved particles than cold water. The hot, salty solution has chemical reactions with the rocks around it. The water picks up more dissolved particles. As it flows through open spaces in rocks, the water deposits solid minerals. When a mineral fills cracks in rocks, the deposits are called veins. Figure 3.20 shows a white quartz vein. When the minerals are deposited in open spaces, large crystals grow. These rocks are called geodes. Figure 3.20 shows a geode that was formed when amethyst crystals grew in an open space in a rock. 
 Question: to come out of a solution as a solid
[EX A]: precipitate

[EX Q]: Context: Early one morning, a taxi pulls up at Tiffany & Co. on Fifth Avenue in New York City, from which elegantly dressed Holly Golightly (Audrey Hepburn) emerges. After looking into the shop's windows, she strolls home. Outside her apartment, she fends off Sid Arbuck (Claude Stroud), her date from the disastrous night before. Later, she is awakened by new neighbor Paul Varjak (George Peppard), ringing her doorbell to get into the building. The pair chat as she dresses to leave for her weekly visit to Sally Tomato (Alan Reed), a mobster incarcerated at Sing Sing prison. Tomato's lawyer, O'Shaughnessy, pays her $100 a week to deliver "the weather report". Audrey Hepburn as Holly Golightly As she is leaving for Sing Sing, Holly is introduced to Paul's "decorator", wealthy older woman Emily Eustace Failenson (Patricia Neal), whom Paul nicknames "2E". That night, Holly goes out onto the fire escape to elude an over-eager date (Mel Blanc). She peeks into Paul's apartment and sees 2E leaving money and kissing Paul goodbye. After 2E leaves, Holly enters Paul's apartment and learns that he is a writer who has not had anything published since a book of vignettes five years before. Holly, in turn, explains that she is trying to save money to support her brother Fred when he gets out of the Army. The pair fall asleep, but are awakened when Holly has a nightmare about Fred. She later buys Paul a typewriter ribbon to apologize and invites him to a party at her apartment. There, Paul meets her Hollywood agent, O. J. Berman (Martin Balsam), who describes Holly's transformation from country girl into Manhattan socialite. He is also introduced to Jose da Silva Pereira (Jose Luis de Vilallonga), a wealthy Brazilian politician, and Rusty Trawler (Stanley Adams), the "ninth richest man in America under 50." In the days that follow, Paul and Holly become closer. One day, 2E enters Paul's apartment, worried that she is being followed. Paul tells her that he will investigate and eventually confronts Doc Golightly (Buddy Ebsen), Holly's estranged husband. Doc explains that Holly's real name is Lula Mae Barnes. They married when she was 13, and he wants to take her back to Texas, as Fred will be returning. After Paul reunites Holly and Doc, she tells Paul the marriage was annulled. At the bus station, she tells Doc she is not going with him. Doc leaves broken-hearted. After drinking at a club, Paul and Holly return to her apartment, where she drunkenly tells him that she plans to marry Trawler for his money. A few days later, Paul learns that one of his short stories will be published. On the way to tell Holly, he sees a newspaper headline stating that Trawler has married someone else. Holly and Paul agree to spend the day together, taking turns doing things that each has never done before. At Tiffany's, Paul has the ring from Doc Golightly's box of Cracker Jack engraved as a present for Holly. After spending the night together, he awakens to find her gone. When 2E arrives, Paul ends their relationship. She calmly accepts, having earlier concluded that he and Holly are in love. Holly schemes to marry Jose for his money, which angers Paul. After Holly receives a telegram notifying her of Fred's death, she trashes her apartment. Months later, Paul has moved out. He is invited to dinner by Holly, who is leaving the next morning for Brazil to continue her relationship with Jose. However, they are arrested in connection with Sally Tomato's drug ring, and Holly spends the night in jail. The next morning, Holly is released on bail and finds Paul waiting, and they take a cab. He has her cat and a letter from Jose explaining he must end their relationship due to her arrest. Holly insists she will go to Brazil anyway, asks the cab to pull over, and releases the
