Geography (from Greek γεωγραφία, geographia, literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first person to use the word γεωγραφία was Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be.

Geography is often defined in terms of two branches: human geography and physical geography. Human geography deals with the study of people and their communities, cultures, economies, and interactions with the environment by studying their relations with and across space and place. Physical geography deals with the study of processes and patterns in the natural environment like the atmosphere, hydrosphere, biosphere, and geosphere.

Dawson Creek
Dawson Creek is a small city in northeastern British Columbia, Canada. It covers an area of 20.66 square kilometres (7.98 sq mi)* in the dry and windy prairie land of the Peace River Country. The city is in the British Columbia Peace Lowland ecosection of the Canadian Boreal Plains ecozone on the continental Interior Platform. Located in the Cordillera Climatic Region, it lies at the southern end of a subarctic climate. The 1941 census, the first to include Dawson Creek as a defined subdivision, counted 518 residents. In 2011 the city had a population of 11,583. Growth slowed in the 1960s, with the population reaching its all-time high in 1966, although since 1992 the city has grown and undergone several boundary expansions. Dubbed "The Capital of the Peace", it is a service centre for the rural areas south of the Peace River and the seat of the Peace River Regional District. Once a small farming community, Dawson Creek became a regional centre when the western terminus of the Northern Alberta Railways was extended there in 1932. The community grew rapidly in 1942 as the US Army used the rail terminus as a transshipment point during construction of the Alaska Highway. In the 1950s the city was connected to the interior of British Columbia via a highway and railway through the Rocky Mountains.

Featured biography

Alfred 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.
