Continents Crossed by the Equator: South America & Africa (Ordered by Size)

The equator crosses two continents:

1. South America (Ecuador, Colombia, Brazil)
2. Africa (Gabon, Congo, DR Congo, Uganda, Kenya, Somalia, São Tomé & Príncipe)

Ordered by land area (largest to smallest):

1. Africa — 30.37 million km²
2. South America — 17.84 million km²

Note: The equator also crosses Asia (Indonesia — islands of Sumatra, Borneo, Sulawesi, Halmahera; and territorial waters of Maldives, Kiribati). However, by standard continental definitions (landmasses), it crosses the Asian continental shelf but not the mainland. Most geographic authorities list three continents (South America, Africa, Asia) or two (excluding Asia's island portions). The question's premise ("those in order") implies two; Africa is larger than South America.
