Mention the characteristic features of the
Great Dividing Range in respect to its altitude
and gradient
?
Answers
Answer:
At some high hill passes the range provides cool sites appropriate for vineyards.[16]
Railways Edit
A number of scenic railways, such as this one at Katoomba, climb various shorter routes along the range
The engineers of early rail passages across the Great Dividing Range needed to find low sections of the range to cross, as well as suitable, "low" gradient paths up the mountains on either side. Rail passages include:
Townsville-Mt Isa
Rockhampton-Winton
Brisbane–Toowoomba (1867) (2.0% gradient)
Newcastle–Tamworth (c 1870), summit at Ardglen Tunnel (2073' HASL)
Sandy Hollow to Maryvale Railway Line started in the 1930s to Maryvale (Main Western Railway Line), completed the 1980s to Gulgong (Sandy Hollow–Gulgong Section), summit just west of Ulan - (500M / 1640') The lowest, 4th & last crossing in NSW.
Sydney–Lithgow (1869), crossing the range via the Blue Mountains (summit near Bell 3507' HASL) (3.00% gradient) [17]
Sydney–Goulburn (1869), though the divide is actually a few kilometres further west near the crossing with Parkesbourne Road near Cullerin. The next 300 km descending to Wagga Wagga was originally fast, but regrading in the 1920s introduced many curves.
Melbourne–Seymour, crossing the range near Heathcote Junction (1872) (2.08% gradient)
Melbourne–Bendigo, crossing the range near Woodend (1862) (1093' HASL)
Melbourne–Ararat (1875) via Ballarat
Road transport Edit
Many of Australia's highways such as the Alpine Way, Great Alpine Road, Hume Highway, Northern Highway, Melba Highway, Maroondah Highway, Sunraysia Highway, Federal Highway, Great Western Highway, Capricorn Highway, Cunningham Highway, New England Highway, Bruxner Highway, Oxley Highway, Warrego Highway, Waterfall Way, Thunderbolts Way, the Calder Highway, the Western Highway, and the Murray Valley Highway traverse parts of the range.
The Great Dividing Range, or the Eastern Highlands, is Australia's most substantial mountain range and the fifth longest land-based range in the world. It runs roughly parallel to the East Coast of Australia and stretches more than 3,500 kilometres (2,175 mi) from Dauan Island in the Torres Strait off the northern tip of Cape York Peninsula, Queensland, running the entire length of the eastern coastline through New South Wales, then into Victoria and turning west, before finally fading into the central plain at the Grampians in western Victoria.
