QUES: Flowing water causes sediment to move. Flowing water can erode both rocks and soil. You have already learned that materials can dissolve in water. With enough time, even rocks can be dissolved by water. This process happens really slowly. It may take over a million years to dissolve a rock. It doesnt matter how big the rock is. With enough time, flowing water can dissolve it. Moving water also has the ability to move small pieces of rock and soil. How can water move a rock? Doesnt it need energy? Of course, water gets its energy because it is moving. Moving water has kinetic energy. Things that have more energy can do more work. When water stops moving it will have no energy. It will no longer be able to move the rock and soil. When this happens the rock and soil will settle to the bottom of the calm water. Scientists call this process deposition.

MY QUESTION: How long might it take for water to dissolve a rock?

QUES: Over the centuries, the living here has always been easy enough to attract a steady stream of immigrants. Bountiful food sources might have made Malaysia an inviting place for the contemporaries of Java Manin 230,000 b.c. But thus far, the country's earliest traces of homo sapiens, found in the Niah Caves of northern Sarawak, are fragments of a skull dating to 40,000 b.c. On the peninsula, the oldest human-related relics (10,000 b.c. ) are Stone Age tools of the Negritos. These small, dark Melanesians are related in type to Australian aborigines and are confined today to the forests of the northern highlands. By 2,000 b.c. , these timid, gentle nomads hunting with bow and arrow were driven back from the coasts by waves of sturdy immigrants arriving in outrigger canoes equipped with sails. Mongolians from South China and Polynesian and Malay peoples from the Philippines and the Indonesian islands settled along the rivers of the peninsula and northern Borneo. They practiced a slash-and-burn agriculture of yams and millet, a technique that exhausted the soil and imposed a semi-nomadic existence from one jungle clearing to another. Families lived in wooden longhouses like those still to be seen today among the Iban peoples of Sarawak. Another unit was added on to the communal dwelling each time a marriage created a new family. Other tough migrants from the South Seas settled along the coastssailors, fishermen, traders (for the most part pirates)known euphemistically as orang laut (sea people).

MY QUESTION: What peoples practiced slash and burn agriculture techniques?

QUES: We waited for half an hour, watching the smoke curling over the house, and then, judging that the Indians had made off for fear of being ambushed, we crossed the clearing. It took but a glance to read the story. The women had been washing by the little brook before the cabin, with the children playing about them, when the Indians had come up and with a single volley killed them all except the child we had heard crying. They had swooped down upon their victims, torn the scalps from their heads, looted the house, and set fire to it. We dragged out the body of the woman which had been thrown within, in the hope that a spark of life might yet remain, but she was quite dead. Beneath the warrior Spiltdorph had shot we found the child. It was a boy of some six or seven years, and so covered with blood that it seemed it must be dead. But we stripped it and washed it in the brook, and found no wounds upon it except in the head, where it had been struck with a hatchet before its scalp had been stripped off. The cold water brought it back to life and it began to cry again, whereat Spiltdorph took off his coat and wrapped it tenderly about it.

QUES: Before the mysterious disappearance of one of its passenger jets this month, Malaysia wasn't a country used to finding itself dominating headlines around the world. Some of its Southeast Asian neighbors, including Indonesia and the Philippines, have suffered devastating natural disasters in recent years and are all too familiar with the media frenzy that accompanies a major crisis. But Malaysia has largely managed to stay out of the international spotlight since its independence from British colonial rule more than half a century ago. "It is one of these countries, because of its geography, that doesn't have earthquakes," said Ernest Bower, senior adviser for Southeast Asia studies at the Center for Strategic and International Studies. "It doesn't have tsunamis. It hasn't been tested with a disaster like this." The disappearance of Malaysia Airlines Flight 370 has thrust the government into the dazzling glare of worldwide attention. And it hasn't emerged with very good grades. "I think on a stress test, they're failing," Bower told CNN's Jake Tapper, pointing to the government's coordination of different agencies and communication with other countries. China among critics Criticism and complaints have come from other countries involved in the search for the missing plane, including China and Vietnam, and from the relatives of passengers. Malaysian officials have created confusion by issuing contradictory statements on key aspects of the investigation. The majority of the people on board the plane were Chinese, and Beijing has increasingly voiced its displeasure with the search, especially after Malaysia announced over the weekend that evidence suggested the plane had been deliberately flown west into the Indian Ocean, away from its last confirmed location over the South China Sea. "The new information means the intensive search in the South China Sea for the whole past week was worthless and would never bear fruit," said a commentary published by China's state-run news agency Xinhua. "Even worse, the golden time for saving possible survivors, if any, was generously wasted."
