North America, the third largest continent, extends from the tiny Aleutian Islands in the northwest to the Isthmus of Panama in the south. The continent includes the enormous island of Greenland in the northeast and the small island countries and territories that dot the Caribbean Sea and western North Atlantic Ocean.

fourth largest of the world’s continents. The continent is compact and roughly triangular in shape, being broad in the north and tapering to a point—Cape Horn, Chile—in the south. South America is bounded by the Caribbean Sea to the northwest and north, the Atlantic Ocean to the northeast, east, and southeast, and the Pacific Ocean to the west. In the northwest it is joined to North America by the Isthmus of Panama, a land bridge narrowing to about 50 miles (80 km) at one point. Drake Passage, south of Cape Horn, separates South America from Antarctica.

Europe is the western part of the continent of Eurasia, often thought of as its own continent. It is separated from Asia by the Ural Mountains in Russia and the Bosporus strait in Turkey.Europe is bordered by water on three sides. On the west is the Atlantic Ocean. To the north is the Arctic Ocean. The Mediterranean Sea separates Southeastern Europe from Africa. On the eastern border of Europe are the Ural River and Ural Mountains.

Africa is the second largest continent in the world. It makes up about a fifth of the world’s land. It is surrounded by large areas of water. There are 54 fully recognised and independent countries in Africa, and 14.7% (1.216 billion) of the world’s population lives there.

The Middle East is, very generally speaking, an arid region in Southwest Asia and part of North Africa stretching from the Mediterranean Sea to the Persian Gulf, bounded by the Black and Caspian Seas in the north and the Sahara Desert and Indian Ocean in the south.

Largest continent, situated in the Eastern Hemisphere, bounded by the Arctic, Pacific, and Indian oceans, and separated from N Europe by the Ural Mountains: it includes, in addition to the nations on the land mass, Japan, the Philippines, Taiwan, Malaysia, & Indonesia
