The Geography Portal
Geography (from Greek γεωγραφία, geographia, literally "earth description") is a field of science devoted to the study of the lands, the features, the inhabitants, and the 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 the Earth and its human and natural complexities—not merely where objects are, but how they have changed and come to be.
Geography is often defined in terms of the two branches of 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.
The four historical traditions in geographical research are: spatial analyses of natural and the human phenomena, area studies of places and regions, studies of human-land relationships, and the Earth sciences. Geography has been called "the world discipline" and "the bridge between the human and the physical sciences".
Lake Burley Griffin
is a lake
in the centre of Canberra
, Australia's federal capital city
. It was created in 1963 after the Molonglo River
, which runs through the city centre
, was dammed
. Named after Walter Burley Griffin
, the architect
who won the design competition for the city of Canberra, the lake is located in the approximate geographic centre of the city, according to Griffin's original designs. Numerous important institutions, such as the National Gallery of Australia
, National Museum of Australia
, National Library of Australia
, and the High Court of Australia
lie on its shores, and Parliament House
is a short distance away. Its surrounds are also quite popular with recreational users, particularly in the warmer months. Though swimming in the lake is uncommon, it is used for a wide variety of other activities, such as rowing
, and sailing
. The lake's flow is regulated by the 33 metre tall Scrivener Dam, which is designed to handle a once in 5000 year flood event, and in times of drought, water levels can be maintained through the release of water from Googong Dam
. The lake is an ornamental body with a length of 11 kilometres (6.8 mi); at its widest, it measures 1.2 kilometres (0.75 mi). It has an average depth of 4 metres (13 ft) and a maximum depth of about 18 metres (59 ft) near the Scrivener Dam

. Boone is most famous for his exploration and settlement of what is now the U.S. Commonwealth of Kentucky
, which was then beyond the western borders of the Thirteen Colonies
. Despite resistance from American Indians
, for whom Kentucky was a traditional hunting ground, in 1775 Boone blazed the Wilderness Road
through the Cumberland Gap
and into Kentucky. There he founded Boonesborough
, one of the first English-speaking settlements beyond the Appalachian Mountains
. Before the end of the 18th century, more than 200,000 European people migrated to Kentucky and Virginia by following the route marked by Boone. He was a legend in his own lifetime, especially after an account of his adventures was published in 1784, making him famous in America and Europe. After his death, he was frequently the subject of tall tales and works of fiction. His adventures—real and legendary—were influential in creating the archetypal Western hero of American folklore. In American popular culture, he is remembered as one of the foremost early frontiersmen, even though the mythology often overshadows the historical details of his life.
