• Antarctica: The least populated continent, Antarctica is primarily a research region with extreme weather conditions and vast ice formations.

Oceans

The Earth’s surface is covered by approximately 71% water, primarily oceans. There are five major oceans:

• Pacific Ocean: The largest and deepest ocean, it spans between Asia and Australia to the west and the Americas to the east.
• Atlantic Ocean: The second-largest ocean, known for its historical significance in trade and exploration.
