• Samuel Hearne 1745-1792 Samuel Hearne, dès la deuxième moitié du XVIIIe siècle, ouvrit à l'exploration de la race blanche les territoires stériles qui terminent le continent américain sur les rives de l'océan Glacial.

  possibilités alimentaires étaient en grande partie subordonnées aux déplacements des caribous arctiques. Lorsque Samuel Hearne quitta le Fort Churchill, en novembre 1769, l'hiver était trop avancé déjà, et les animaux avaient déserté les Barren Grounds. Les Indiens (Chipewyan) qui devaient guider l'expédition se découragèrent rapidement et faussèrent compagnie à l'explorateur, ne lui laissant d'autre alternative que de renoncer momentanément à son projet. En février 1770, il en tenta de nouveau...

• Valley.

  Except in mountainous terrain, rivers are almost always flanked by floodplains. Floodplains are flat wide deposits of alluvium, river-deposited sediment, on either side of the river channel. During floods, a river overflows its banks and spreads out the sediment near the river to form a floodplain. Floodplains of large rivers, such as thoseof the Mississippi River, can be flat areas tens of kilometers across. River channels migrate back and forth across their floodplains as alluvium is repeate...

  Yangtze Gorges, ChinaThe Yangtze Gorges, also known as the Three Gorges, once drew many tourists with their scenic beauty. However, the Three GorgesDam that was constructed in the early 21st century raised the level of the Yangtze River upstream, forming a deep reservoir thatflooded the gorges.Dean Conger/Corbis The Yangtze originates in the mountains of southwestern Qinghai Province, located in the northern Tibetan Plateau. The river has three headwaters, the highest of whichdescends from an el...

• Valley - geography.

  B Longitudinal Profile A graph of the slope of a river channel at each point along its course is called a longitudinal profile . In most cases, the slope of a river becomes less steep as it flows from its headwaters to the ocean. Slopes as high as 200 m/km (1000 ft/mi) can be found in mountainous terrain, but slopes of about 2 m/km (10 ft/mi) are more typical in themiddle section of such valleys. Slopes as low as 2 cm/km (1 in/mi) can be found in rivers close to the ocean. In most rivers there...

Hector’s recumbent body is seen in front of a chariot.Chris Hellier/Corbis Achilles fought many battles during the Greeks’ ten-year siege of Troy. When the Mycenaean king Agamemnon sei...

• Hippopotamus - biology.

  hippo backs up to its droppings and uses its tail as a paddle, flicking the dung through the air. This creates a pile that can become several meters wide over time. Male river hippos start to establish territories when they are in their early 20s, and they may eventually control more than 250 m (820 ft) of the water's edge.Subordinate males come and go freely, but a rival male will spark a confrontation if it tries to intrude. The territory owner and intruder face each other open-mouthedand, if...

• Yangtze - Geography.

  A Agriculture and Industry Today about 400 million people, or about one-third of the population of China, live in the Yangtze Basin. Many are engaged in agriculture. The basin contributes nearlyhalf of China’s crop production, although only one-quarter of the basin is arable. The most fertile areas for farming are the Sichuan Basin, the plains between theYangtze and its tributary the Han, and the plains of the lower basin. In all about 40 percent of the cereals, more than 30 percent of the cott...

• Idaho - geography.

  Idaho-Montana state line in the southern part of the Bitterroot Mountains. Consequently, nearly all the rivers in the state drain toward the Pacific. Most of Idaho lieswithin the drainage basin of the Columbia River system. The Snake River, which is the chief river in southern and central Idaho, follows a crescent-shaped course forabout 790 km (about 490 mi) across southern Idaho. It then swings northward along the Idaho state line and joins the Columbia River in Washington. Major tributariesof...

• Northwest Territories - Geography.

  million years ago by the severe bending (folding) and faulting (breaking) of sedimentary rock that was once part of the Interior Plains. During the Wisconsin Ice Age,alpine glaciers covered the Cordillera, and the movement of the glaciers created razor-sharp peaks and ridges in these mountains. The moving glaciers also createdbroad U-shaped valleys. To the east of the Interior Plains, the ancient rocks of the Canadian Shield are exposed at the Earth’s surface, resulting in a rough, rolling terra...

• Portland - geography.

  In the 19th century Portland had large Chinese, Scandinavian, and Italian immigrant communities. Today, however, little remains of these early communities, and the cityhas relatively small minority populations. According to the 2000 census, whites made up 77.9 percent of the population, blacks 6.6 percent, Asians 6.3 percent, NativeAmericans 1.1 percent, and Native Hawaiians and other Pacific Islanders 0.4 percent. People of mixed heritage or not reporting race were 7.7 percent of the population...

• Nile - Geography.

  The Nile is also a source of hydroelectric power ( see Waterpower), although the river’s potential as a source of electricity has yet to be fully exploited. Dams to provide hydroelectricity (and control flooding) have been constructed along the Nile in Egypt, Sudan, and Uganda. Additional hydroelectric projects are planned.

• Missouri - geography.

  Saint Francois Mountains, at the eastern end of the crest of the dome. Only in these mountains have the sedimentary rocks been sufficiently eroded away so that theunderlying igneous rocks are exposed. They form the rounded, knoblike peaks of an old mountain range. The peaks project, in isolation or in clusters, between 230 and300 m (750 and 1,000 ft) above the surrounding sedimentary basins. One of these knobs, Taum Sauk Mountain, reaches 540 m (1,772 ft) above sea level and is thehighest point...
