What are the geographical factors that led to Argentina invading Falkland islands?

Argentina has claimed sovereignty over the Falkland Islands since 1833, arguing that the islands are geographically part of the South American continental shelf. The islands are located about 500 kilometers east of Argentina's mainland and 1,200 kilometers west of the African coast. Their geographical isolation has caused some to refer to them as "Britain's loneliest outpost." Here are some key geographical factors that contributed to Argentina's invasion of the Falkland Islands in 1982:

-Proximity to Argentina:

The proximity of the Falkland Islands to Argentina, which makes up part of their strategic importance to the continental South American nation; and

-Location on South American continental shelf:

The Falklands rest over Argentine oil drilling spots with an estimated 60 billion dollars of unrefined crude.
