Input: You may wonder if there are other examples of static discharge. The answer is yes. Lightning is a form of static discharge. It is much more dramatic than what happens between you and the door knocker, but it is the same principle. You can see how it occurs in the following diagram and animation. You have no doubt seen lightning in a rainstorm. What does lighting have to do with static electricity? As it turns out, everything! During a rainstorm, clouds develop regions of different charges. This happens due to the movement of air molecules, water drops, and ice particles. The negative charges are concentrated at the base of the clouds. The positive charges are concentrated at the top. The negative charges repel electrons on the ground below. The ground then becomes positively charged. Over time the differences increase. Eventually the electrons are discharged. This is what we see as lightning. You can watch an awesome slow-motion lightning strike below.

Does the response "Wind motion" correctly answer the question "Are there other examples of static discharge?"?

The inhabited history of the Las Vegas Valley stretches to 23,000 b.c. , when much of the area was covered by a prehistoric lake. During this period, the indigenous people lived in caves, hunting the mammals that gathered at the shoreline. The landscape of the valley changed dramatically over the next 200 centuries. The glaciers feeding the lake melted away and the lake evaporated. Fossils tell an obscure story of man's slow and sporadic development. Around 3000 b.c. , native Archaic Indians began to develop a lasting hunting and gathering culture. By this time, the valley was in much the same geographic state as it exists in today, with one exceptionthe presence of artesian springs that bubbled to the surface in several areas. These springs fed a network of streams draining through the Las Vegas Wash to the Colorado River. The areas surrounding the springs were desert oases: sprawling collections of grasses, trees, and wildlife. Many springs lay in areas that would eventually become the center of the modern Las Vegas metropolis. For about 4000 years, the Archaics thrived in a culture that included many signs of early civilization. Signs of even more advancement appeared halfway through the first millennium a.d. , when the Anasazi Indians inhabited the valley. Far more progressive than the Archaics, the Anasazi utilized such formal agricultural techniques as irrigation to assist their harvest. This permitted the Anasazi to achieve a benchmark of advanced societythe ability to live in permanent shelters year-round without need to follow wildlife. Mysteriously, the Anasazi vanished from the valley around a.d.

I am very hungry. I look for my mother. When is dinner? I ask. Dinner is at six, my mother says. What can we eat? I ask. We can pick food from our garden, she says. I help her pick corn, beans, and peas. The corn is yellow and white. The beans are small and brown. The peas are green and round. I put the beans in a basket. I put the peas in a bowl. Mother brings the corn. We go inside. I have dirty hands. I wash my hands with soap and water. The water is warm. My hands are now clean. Mother lets me stir the beans. I fill a pot with water. Mother puts the corn into the pot. She puts the pot on the stove. The water boils. Mary is my sister. Mary puts four plates on the table. Each plate is blue. We each eat two pieces of meat. I eat more corn than Mary. Mary eats more beans than our mother. What did you learn today? Mary asks. I can spell ten new words, I say. Mary can only spell two words.

Question: "Why do I look for my mother?"

Response: "To collect corn, beans and peas"

The White Rajahs of Borneo: In the 19th century, Borneo remained relatively undeveloped. Balanini pirates, fervent Muslims, disputed the coast of northeastern Borneo (modern Sabah) with the sultanate of Brunei. Sarawak's coast and jungle interior were controlled by the IbanSea Dayak pirates and Land Dayak slash-and-burn farmers. (The Dayaks practiced head-hunting, a ritual that was believed to bring spiritual energy to their communities. ) The region was unproductive and without great resources, except for the Sarawak river valley, where the Chinese mined for gold and antimony. Brunei chiefs traded the metals through Americans in Singapore. In 1839, the governor of Singapore sent James Brooke (18031868) to promote trade links with the Sultan of Brunei. He had been an audacious cavalry officer in the Anglo-Burmese wars and now exploited the situation for his own benefit. In exchange for helping the regent end a revolt of uppity Malay chiefs, Brooke was made Rajah of Sarawak in 1841, with his capital in Kuching (founded by the Malays just 11 years earlier). He tried to halt the Dayaks' piracy and head-hunting while defending their more "morally acceptable" customs. His attempts to limit the opium trade met with resistance by the Chinese in Bau, who revolted. His counter-attack with Dayak warriors drove the Chinese out of Bau and across the Sarawak border. Thereafter, Chinese settlement was discouraged and did not achieve the commercial dominance it enjoyed on the peninsula. In 1863, Brooke retired to Britain, handing Sarawak over to his nephew Charles. More reserved and remote but a better administrator and financier than his uncle, Charles Brooke imposed on his men his own austere, efficient style of life. He brought Dayak leaders onto his ruling council but favored the time-honored colonial practice of divide-and-rule by pitting one tribe against another to keep the peace. Northeast Borneo (Sabah) was "rented" from the Sultan of Brunei by British businessman Alfred Dent. Dent was operating a royal charter for the British North Borneo Companya charter similar to that of the EIC.
