The Geography Portal[[Image:|200px|Settlement geography]] Geography is the science that studies the lands, the features, the inhabitants, and the phenomena of the Earth. A literal translation would be "to describe or write about the Earth". The first person to use the word "geography" was Eratosthenes (276–194 BC). Four historical traditions in geographical research are the spatial analysis of the natural and the human phenomena (geography as the study of distribution), the area studies (places and regions), the study of the human-land relationship, and research in the Earth sciences. Modern geography is an all-encompassing discipline that foremost seeks to understand the Earth and all of its human and natural complexities—not merely where objects are, but how they have changed and come to be. Geography has been called "the world discipline" and "the bridge between the human and the physical science". Geography is divided into two main branches: human geography and physical geography.

Surtsey (Icelandic, meaning "Surtr's island") is a volcanic island off the southern coast of Iceland. At 63°18′11″N 20°36′17″W / 63.303°N 20.6047°WCoordinates: 63°18′11″N 20°36′17″W / 63.303°N 20.6047°W Surtsey is the southernmost point of Iceland. It was formed in a volcanic eruption which began 130 metres (426 ft) below sea level, and reached the surface on 15 November 1963. The eruption lasted until 5 June 1967, when the island reached its maximum size of 2.7 km2 (1.0 sq mi). Since then, wind and wave erosion have caused the island to steadily diminish in size: as of 2002, its surface area was 1.4 km2 (0.54 sq mi). The new island was named after Surtr, a fire jötunn or giant from Norse mythology. It was intensively studied by volcanologists during its eruption, and afterwards by botanists and biologists as life forms gradually colonised the originally barren island. The undersea vents that produced Surtsey are part of the Vestmannaeyjar (Westmann Isles) submarine volcanic system, part of the fissure of the sea floor called the Mid-Atlantic Ridge. Vestmannaeyjar also produced the famous eruption of Eldfell on the island of Heimaey in 1973. The eruption that created Surtsey also created a few other small islands along this volcanic chain, such as Jólnir and other, unnamed peaks. Most of these eroded away fairly quickly.

Things you can doFeatured biographyAlfred Russel Wallace was a British naturalist, explorer, geographer, anthropologist, and biologist. He is best known for independently proposing a theory of natural selection which prompted Charles Darwin to publish on his own theory. Wallace did extensive fieldwork, first in the Amazon River basin and then in the Malay Archipelago, where he identified the Wallace Line that divides Indonesia into two distinct parts, one with animals more closely related to those of Australia and the other with animals more closely related to those found in Asia. He was considered the 19th century's leading expert on the geographical distribution of animal species and is sometimes called the "father of biogeography". Wallace was one of the leading evolutionary thinkers of the 19th century who made a number of other contributions to the development of evolutionary theory besides being co-discoverer of natural selection. These included the concept of warning colouration in animals, and the Wallace effect, a hypothesis on how natural selection could contribute to speciation by encouraging the development of barriers against hybridization. An account of his observations, The Malay Archipelago, is regarded as probably the best of all journals of scientific exploration published during the 19th century.

It is one of the world's largest river deltas—from Alexandria in the west to Port Said in the east, it covers 240 km of Mediterranean coastline—and is a rich agricultural region. From north to south the delta is approximately 160 km in length. The Delta begins slightly down-river from Cairo. Selected quoteArticles
