question:
Most sedimentary rocks form from sediments. Sediments are small pieces of other rocks, like pebbles, sand, silt, and clay. Sedimentary rocks may include fossils. Fossils are materials left behind by once-living organisms. Fossils can be pieces of the organism, like bones. They can also be traces of the organism, like footprints. Most often, sediments settle out of water (Figure 4.13). For example, rivers carry lots of sediment. Where the water slows, it dumps these sediments along its banks, into lakes and the ocean. When sediments settle out of water, they form horizontal layers. A layer of sediment is deposited. Then the next layer is deposited on top of that layer. So each layer in a sedimentary rock is younger than the layer under it. It is older than the layer over it. Sediments are deposited in many different types of environments. Beaches and deserts collect large deposits of sand. Sediments also continuously wind up at the bottom of the ocean and in lakes, ponds, rivers, marshes, and swamps. Avalanches produce large piles of sediment. The environment where the sediments are deposited determines the type of sedimentary rock that can form. Sedimentary rocks form in two ways. Particles may be cemented together. Chemicals may precipitate. Over time, deposited sediments may harden into rock. First, the sediments are compacted. That is, they are squeezed together by the weight of sediments on top of them. Next, the sediments are cemented together. Minerals fill in the spaces between the loose sediment particles. These cementing minerals come from the water that moves through the sediments. These types of sedimentary rocks are called clastic rocks. Clastic rocks are rock fragments that are compacted and cemented together. Clastic sedimentary rocks are grouped by the size of the sediment they contain. Conglomerate and breccia are made of individual stones that have been cemented together. In conglomerate, the stones are rounded. In breccia, the stones are angular. Sandstone is made of sand-sized particles. Siltstone is made of smaller particles. Silt is smaller than sand but larger than clay. Shale has the smallest grain size. Shale is made mostly of clay-sized particles and hardened mud. Chemical sedimentary rocks form when crystals precipitate out from a liquid. The mineral halite, also called rock salt, forms this way. You can make halite! Leave a shallow dish of salt water out in the Sun. As the water evaporates, salt crystals form in the dish. There are other chemical sedimentary rocks, like gypsum. Table 4.1 shows some common types of sedimentary rocks and the types of sediments that make them up.

question:
What could make Michael Jordon, one of the greatest basketball players in history, shed tears? It was when he became a member of the Basketball Hall of Fame on September 11. The hall is in Springfield, Massachusetts and honors the best basketball players, greatest coaches and other contributors to the game. "The game of basketball has been everything to me ," said Jordan, 46. "It is the place I have always gone when I needed to find comfort and peace." Jordan retired twice in his 15-year career, finishing with 32292 points, the third highest total points in NBA history behind Kareem Abdul-Jabbar and Karl Malone. His average of 30.12 points a game is the best in the League. "One day you might look up and see me playing the game at 50," Jordan said. "Because limits, like fears, are often just an illusion." In other words, it was motivation that made Jordan such a success.. A great career did not mean a smooth one. His high school coach cut him from the team in favor of a taller player when Jordan was in 10thgrade. His college coach wouldn't allow him on the cover of Sports Illustration in 1981 with North Carolina's four other players because Jordan was a freshman. In his first NBA All-Star game, older NBA stars wouldn't throw him the ball because of jealousy. "That burned me up," Jordan said. "But _ don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it."
answer:
Who scored the highest total points in NBA history?

question:
When we are unfamiliar with something,we may feel nervous and fearful.The assistance of others is a good way to help us pull through. I write for a big newspaper, and I wanted to write a story about parachute jumping.To make it a realistic as well as exciting story,I decided that I first had to make a jump myself. Unfortunately,I am not good at any sports of any kind,let alone parachute jumping. My friend Mr. Smith was willing to give me a hand.He took me to a ground school.The first day's training included several hours of instruction but not my first drop from an airplane For this,I had to wait until the following morning. The next morning,after a hurried,anxious breakfast,I was taken to the airfield.There,two heavy parachutes were put on my back,and an orange helmet was pushed down onto my head.Then I was asked to make my way to a small plane which had just stopped slowly on the runway. Once on board,the plane was soon climbing.I began to feel nervous.As we reached one thousand metres,Harry,my teacher, hooked a line from my parachute to a steel ring inside the plane.The line was to pull my parachute open after I jumped. "Get ready, Henry,"Harry said.I moved carefully to the door.I wanted to cry,"No,no,no!"But no word came. "Jump!"Harry called loudly."Jump!" To my surprise,kicking like a frog I did jump.Away from the plane,and down,down I fell,arms stretched.It worked! The air seemed to hold me up.All at once I was very happy. Then I felt a quick pull.My big parachute had opened! It was the best surprise I ever had. I looked down.There were rivers,trees,fields and houses.I heard the soft sound of the air This was fun !
answer:
How did the writer feel after he jumped out of the plane?
