Overview of the Atlantic Ocean and Its Islands
The Atlantic Ocean stretches approximately 41,100,000 square miles (106,460,000 square kilometers), making it the second-largest ocean basin on Earth. It is bordered by the Americas to the west, Europe and Africa to the east, and connects to the Arctic Ocean in the north and the Southern Ocean in the south. Within this vast body of water lie hundreds of islands, many of which are of volcanic origin, while others are continental fragments or coral atolls.
These islands can be categorized based on their geographical location, geological origin, and cultural heritage:
- Macaronesia (including the Azores, Canary Islands, Madeira, and Cape Verde)
- The British and Irish Isles (e.g., the British Isles, Ireland)
- The Caribbean Islands (e.g., Bahamas, Puerto Rico)
- South Atlantic Islands (e.g., Falkland Islands, Saint Helena)
- Other notable islands scattered across the Atlantic basin

Geological Origins of Atlantic Islands
The islands of the Atlantic map are primarily volcanic in origin, formed by tectonic activity and hotspot activity. Their geological origins influence their landscapes, ecosystems, and development.
Volcanic Islands
Most Atlantic islands, such as the Canary Islands, Azores, and Cape Verde, are volcanic. They formed from eruptions of magma that cooled and built up over millions of years.
Characteristics:
- Steep, rugged terrains
- Presence of volcanic cones and craters
- Rich mineral deposits
Continental Fragments
Some islands, like the British Isles and Ireland, are remnants of ancient continental landmasses. They have more complex geological histories involving glaciation and erosion.
Coral Atolls
Certain islands like the Bahamas are formed from coral reefs that build up over submerged volcanic bases, creating low-lying atolls with rich marine life.
