s Land, the Antarctic Peninsula area,
and parts of Ross Island on McMurdo Sound; glaciers form ice shelves
along about half of the coastline, and floating ice shelves constitute
11% of the area of the continent
Elevation extremes:
lowest point: Indian Ocean 0 m
highest point: Vinson Massif 5,140 m
Natural resources: none presently exploited; iron ore, chromium,
copper, gold, nickel, platinum and other minerals, and coal and
hydrocarbons have been found in small, uncommercial quantities
Land use:
arable land: 0%
permanent crops: 0%
permanent pastures: 0%
forests and woodland: 0%
other: 100% (ice 98%, barren rock 2%)
Irrigated land: 0 sq km (1993)
Natural hazards: katabatic (gravity-driven) winds blow coastward from
the high interior; frequent blizzards form near the foot of the
plateau; cyclonic storms form over the ocean and move clockwise along
the coast; volcanism on Deception Island and isolated areas of West
Antarctica; other seismic activity rare and weak
Environment-current issues: in 1995 it was reported that the ozone
shield, which protects the Earth's surface from harmful ultraviolet
radiation, had dwindled to the lowest level recorded over Antarctica
since 1975 when measurements were first taken
Environment-international agreements:
party to: none of the selected agreements
signed, but not ratified: none of the selected agreements
Geography-note: the coldest, windiest, highest, and driest continent;
during summer, more solar radiation reaches the surface at the South
Pole than is received at the Equator in an equivalent period; mostly
uninhabitable
