The Great Barrier Reef and the Great Australian Desert are two notable features of Australia.

Formation of Continents and Oceans

Millions of years ago, all continents formed a single supercontinent called Pangaea.
Over time, Pangaea split into pieces, which drifted away from each other.
The space between the pieces filled up with water, forming continents and oceans.

Oceans

There are five oceans in the world: Pacific, Atlantic, Indian, Arctic, and Southern.

The Pacific Ocean

The Pacific Ocean is the largest and deepest ocean in the world, almost circular in shape.
It separates the Americas from Asia and Australia.
The Mariana Trench, the world's deepest trench (10,994 m), lies in the Pacific Ocean.

The Atlantic Ocean

The Atlantic Ocean is the second largest ocean, shaped like the letter 'S'.
It separates North and South America from Europe and Africa.
The Mid-Atlantic Ridge, a submerged mountain range, is a unique feature of the Atlantic Ocean.

North America is the third-largest continent, stretching from the Arctic Circle to the southern border of Panama.
South America is the fourth-largest continent, connected to North America by the Isthmus of Panama.
Antarctica is the fifth-largest continent, surrounded by the Southern Ocean and covered in ice throughout the year.
Europe is the sixth-largest continent, located in the northern hemisphere and sharing borders with Asia.
Australia is the smallest continent, also an island, and is located entirely in the southern hemisphere.

The Atlantic Ocean is the second-largest ocean, separating North and South America from Europe and Africa.
The Indian Ocean is the third-largest ocean, located between Asia, Australia, and Africa.
