[EX Q]: Context: Weathering changes solid rock into sediments. Sediments are different sizes of rock particles. Boulders are sedi- ments; so is gravel. At the other end, silt and clay are also sediments. Weathering causes rocks at the Earths surface to change form. The new minerals that form are stable at the Earths surface. It takes a long time for a rock or mountain to weather. But a road can do so much more quickly. If you live in a part of the world that has cold winters, you may only have to wait one year to see a new road start to weather (Figure Mechanical weathering breaks rock into smaller pieces. These smaller pieces are just like the bigger rock; they are just smaller! The rock has broken without changing its composition. The smaller pieces have the same minerals in the same proportions. You could use the expression a chip off the old block to describe mechanical weathering! The main agents of mechanical weathering are water, ice, and wind. Rocks can break apart into smaller pieces in many ways. Ice wedging is common where water goes above and below its freezing point (Figure 9.2). This can happen in winter in the mid-latitudes or in colder climates in summer. Ice wedging is common in mountainous regions. This is how ice wedging works. When liquid water changes into solid ice, it increases in volume. You see this when you fill an ice cube tray with water and put it in the freezer. The ice cubes go to a higher level in the tray than the water. You also may have seen this if you put a can of soda into the freezer so that it cools down quickly. If you leave the can in the freezer too long, the liquid expands so much that it bends or pops the can. (For the record, water is very unusual. Most substances get smaller when they change from a liquid to a solid.) Abrasion is another type of mechanical weathering. With abrasion, one rock bumps against another rock. Gravity causes abrasion as a rock tumbles down a slope. Moving water causes abrasion it moves rocks so that they bump against one another (Figure 9.3). Strong winds cause abrasion by blasting sand against rock surfaces. Finally, the ice in glaciers cause abrasion. Pieces of rock embedded in ice at the bottom of a glacier scrape against the rock below. If you have ever collected beach glass or pebbles from a stream, you have witnessed the work of abrasion. Sometimes biological elements cause mechanical weathering. This can happen slowly. A plants roots grow into a crack in rock. As the roots grow larger, they wedge open the crack. Burrowing animals can also cause weathering. By digging for food or creating a hole to live in the animal may break apart rock. Today, human beings do a lot of mechanical weathering whenever we dig or blast into rock. This is common when we build homes, roads, and subways, or quarry stone for construction or other uses. Mechanical weathering increases the rate of chemical weathering. As rock breaks into smaller pieces, the surface area of the pieces increases. With more surfaces exposed, there are more places for chemical weathering to occur. Lets say you wanted to make some hot chocolate on a cold day. It would be hard to get a big chunk of chocolate to dissolve in your milk or hot water. Maybe you could make hot chocolate from some smaller pieces like chocolate chips, but it is much easier to add a powder to your milk. This is because the smaller the pieces are, the more surface area they have. Smaller pieces dissolve more easily. Chemical weathering is different than mechanical weathering. The minerals in the rock change. The rock changes composition and becomes a different type of rock. Most minerals form at high pressure or high temperatures deep within Earth. But at Earths surface, temperatures and pressures are much lower. Minerals that were stable deeper in the crust are not stable at the surface. Thats why chemical weathering happens. Minerals that formed at higher temperature and pressure change into minerals that are stable at the surface. Chemical weathering is important. It

[EX Q]: Context: When once-wealthy string magnate Rudolf Smuntz (William Hickey) dies, he leaves his outdated string factory and a run-down mansion to his two sons, Lars (Lee Evans) and Ernie (Nathan Lane). When Lars refuses a proposal by representatives from the large Zeppco conglomerate to purchase their string factory, his wife April (Vicki Lewis) throws him out. Meanwhile, Ernie serves Mayor McKrinkle (Cliff Emmich) at his restaurant in anticipation of becoming a famous chef for serving such a high-profile guest. However, the mayor is poisoned by a cockroach (which came from Rudolf's old box of Cuban cigars that Ernie took for himself) and suffers two heart attacks, with the latter fatal. As a result, Ernie's restaurant is closed down by the Board of Health. Finding blueprints of the mansion that they decide to live in, Ernie and Lars discover that it is a lost masterpiece designed by famous architect Charles Lyle LaRue. LaRue collector Alexander Falko (Maury Chaykin) makes a proposal, but Ernie refuses under the belief they can make a larger profit by restoration and auction. However, the brothers have already realized that the house has one stubborn occupant: a tiny and treacherous mouse. When a single mousetrap proved to be useless against the mouse, Ernie and Lars cover the entire kitchen floor with a number of mousetraps, but end up trapped in the kitchen when the door is locked. The mouse slips through the maze of traps with ease and drops a cherry, setting off the mousetraps in a dominoes effect. The brothers attempt to kill the mouse with a vacuum cleaner, but are covered with sewage. The brothers purchase a monstrous cat named "Catzilla" to deal with the mouse. Catzilla chases the mouse throughout the house while destroying everything, but gets tricked onto the house's dumbwaiter as the mouse sends him on a one-way trip down to his demise. They then hire an eccentric exterminator named Caesar (Christopher Walken) to handle the mouse, though he is severely injured and hospitalized. Later, Ernie chases the mouse up a chimney and gets stuck, and Lars attempts to light a match while the mouse starts a gas leak, creating an explosion that blasts Ernie out of the chimney and into the lake. Ernie takes a shotgun to fire at the mouse, accidentally shooting a compressed can of pesticide that Caesar left behind, making a large hole. After the two recover, Lars throws an orange at Ernie, but accidentally knocks the mouse unconscious. Unable to finish him off, they instead seal the mouse in a box and mail him to Fidel Castro in Cuba. The brothers reconcile again and finish renovating the house. When the night of the auction arrives, Lars discovers the mouse's box in the snow returned due to insufficient postage and with a big hole gnawed through it. Lars and Ernie panic upon seeing the mouse return, but attempt to maintain their composure as the auction continues. The mouse also devours Rudolf's "lucky string," which he gave to the brothers before his death, making their vendetta even more personal. The brothers desperately attempt to flush out the mouse by feeding a hose into the wall. As the auction reaches a record $25 million bid, the house rapidly floods through the walls and the floors, causing everyone to be washed out of the house as it promptly collapses. The brothers' only consolation is the fact that the mouse must finally be dead as their father's "lucky string" is found in the wreckage. With nowhere else to go, the brothers return to the factory and fall asleep, with only a single chunk of cheese for food. Having followed them, the mouse restarts and feeds the cheese into the machinery inventing the world's first string cheese, which inspires Ernie and Lars. Ernie and Lars end their war with the mouse and have successfully rebuilt the factory as a novelty string cheese company. Lars has begun a relationship with one of the two sisters Hilde, and Ernie puts his culinary skill to work in developing new cheese flavors with the mouse as his personal taste-tester.
