Mount Usborne
Mount Usborne ( es, Cerro Alberdi) is a mountain on East Falkland. At above sea level, it is the highest point in the Falkland Islands. It is only taller than Mount Adam, the highest peak on West Falkland. The mountain is referenced by Charles Darwin in Chapter 9 of '' Zoology of the Voyage of H.M.S. Beagle''. It is named after Alexander Burns Usborne, master's assistant on , the ship that took Darwin on his famous voyage. As one of the highest mountains of the Falklands, it experienced some glaciation. The remains of glacial cirques can be seen on the mountain. The handful of Falklands mountains over have: :''"pronounced corries with small glacial lakes at their bases, morainic ridges deposited below the corries suggest that the glaciers and ice dome Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors.

East Falkland
East Falkland ( es, Isla Soledad) is the largest island of the Falklands in the South Atlantic, having an area of or 54% of the total area of the Falklands. The island consists of two main land masses, of which the more southerly is known as Lafonia; it is joined by a narrow isthmus where the settlement of Goose Green is located, and it was the scene of the Battle of Goose Green during the Falklands War. The two main centres of population in the Falklands, Stanley and Mount Pleasant, which are both in the northern half of East Falkland, are home to three-quarters of the island's population. Geography East Falkland, which has an area of , a little over half the total area of the islands consists of two land masses of approximately equal size. The island is almost bisected by two deep fjords, Choiseul Sound and Brenton Loch-Grantham Sound which are separated by the wide isthmus that connects Lafonia in the south to the northern part of East Falkland. The island's coastline h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falkland Islands
The Falkland Islands (; es, Islas Malvinas, link=no ) is an archipelago in the South Atlantic Ocean on the Patagonian Shelf. The principal islands are about east of South America's southern Patagonian coast and about from Cape Dubouzet at the northern tip of the Antarctic Peninsula, at a latitude of about 52°S. The archipelago, with an area of , comprises East Falkland, West Falkland, and 776 smaller islands. As a British overseas territory, the Falklands have internal self-governance, but the United Kingdom takes responsibility for their defence and foreign affairs. The capital and largest settlement is Stanley on East Falkland. Controversy exists over the Falklands' discovery and subsequent colonisation by Europeans. At various times, the islands have had French, British, Spanish, and Argentine settlements. Britain reasserted its rule in 1833, but Argentina maintains its claim to the islands. In April 1982, Argentine military forces invaded the islands. British a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Mount Adam, Falkland Islands
Mount Adam (Spanish: "Monte Independencia/Monte Beaufort") is a mountain on West Falkland, part of the Hill Cove Mountains range. It is the highest mountain on West Falkland and is the second highest in the islands. It has the remains of glacial cirques on it, and is only lower than Mount Usborne, the highest peak of the Falkland Islands on East Falkland. Its summit is at . It is south west of Mount Edgeworth. The closest settlements are Hill Cove to the North, and Chartres to the South. As one of the highest mountains of the Falklands, it experienced some glaciation. The handful of mountains over have: :''"pronounced corries with small glacial lakes at their bases, morainic ridges deposited below the corries suggest that the glaciers and ice domes were confined to areas of maximum elevation with other parts of the islands experiencing a periglacial climate''"Strange, Ian (1983) ''The Falkland Islands'' References * Stonehouse, B (ed.)

West Falkland
West Falkland ( es, Isla Gran Malvina) is the second largest of the Falkland Islands in the South Atlantic. It is a hilly island, separated from East Falkland by the Falkland Sound. Its area is , 37% of the total area of the islands. Its coastline is long. Population The island has fewer than 200 people, scattered around the coastline. The largest settlement is Port Howard on the east coast, which has an airstrip. Other settlements include Albemarle, Chartres, Dunnose Head, Fox Bay, Fox Bay West, Hill Cove, Port Stephens, and Roy Cove, most of which are linked by road and also have airstrips and harbours. In 1986, the population was 265, in 2001, it had fallen to 144 and rose to 160 in 2016. Because West Falkland is outside Stanley or RAF Mount Pleasant on East Falkland it is considered part of the "camp", a Falklander term for the area outside the main settlement. Geography and wildlife West Falkland is hillier on the side closest to East Falkland. The principal mounta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoology Of The Voyage Of H
Zoology ()The pronunciation of zoology as is usually regarded as nonstandard, though it is not uncommon. is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and made use of this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. The Greek physician Galen studied human anatomy and was one of the greatest surgeons of the ancient world, but after the fall of the Western Roman Empire a ...

Glaciation
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period ...

Cirque
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the down ...

Glacial Lake
A glacial lake is a body of water with origins from glacier activity. They are formed when a glacier erodes the land and then melts, filling the depression created by the glacier. Formation Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. This is apparent in the Lake District in Northwestern England where post-glacial sediments are normally between 4 and 6 metres deep. These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations and chatter marks. These lakes are clearly visible in aerial photos of landforms in regions that were glaciated during the last ice age. The formation and characteristics of glacial lakes vary between location and can be classified into glacial erosion lake, ice-bloc ...
