evidence: About 400 million years ago, some of the rocks that make up the Falkland Islands were part of the supercontinent of Gondwana, crunched between southern Africa and what is now Queen Maud Land, Antarctica. When tectonic forces tore Gondwana apart, the Falkland Islands were left behind like crumbs as a massive geologic cookie was split into pieces. Today, the islands are situated about 600 kilometers (400 miles) east of Argentina and 1,350 kilometers (850 miles) north of the Antarctic Circle. There are 778 islands in this territory of the United Kingdom, but just two large islands—East Falkland and West Falkland—comprise the bulk of the Connecticut-sized landmass. The Falkland Islands have a cool, moist climate that varies minimally throughout the year. Average annual temperatures are about 5.6°C (42°F). Temperatures reach as high as 24°C (76°F) in summer and as low as -5°C (22°F). Rainfall is comparatively low and evenly distributed throughout the year, averaging 625 millimeters (25 inches) in Stanley, the capital city.
