Atlantic Ocean

Saint Kitts, officially Saint Christopher, is an island in the West Indies. The west side of the island borders the Caribbean Sea, and the eastern coast faces the Atlantic Ocean. Saint Kitts and the neighbouring island of Nevis constitute one country: the Federation of Saint Kitts and Nevis. Saint Kitts and Nevis are separated by a shallow 3-kilometre (2 mi) channel known as "The Narrows".

Saint Kitts became home to the first Caribbean British and French colonies in the mid-1620s. Along with the island of Nevis, Saint Kitts was a member of the British West Indies until gaining independence on 19 September 1983.

The Caribbean is a region in the middle of the Americas centered around the Caribbean Sea in the North Atlantic Ocean, mostly overlapping with the West Indies. Bordered by North America to the north and also the west through Central America, and South America to the south, it comprises numerous islands, cays, islets, reefs, and banks.

It includes the Lucayan Archipelago, Greater Antilles, and Lesser Antilles of the West Indies; the Quintana Roo islands and Belizean islands of the Yucatán Peninsula; and the Bay Islands, Miskito Cays, Archipelago of San Andrés, Providencia, and Santa Catalina, Corn Islands, and San Blas Islands of Central America. It also includes the coastal areas on the continental mainland of the Americas bordering the region from the Yucatán Peninsula in North America through Central America to the Guianas in South America.

The South American plate is a major tectonic plate which includes the continent of South America as well as a sizable region of the Atlantic Ocean seabed extending eastward to the African plate, with which it forms the southern part of the Mid-Atlantic Ridge.

The easterly edge is a divergent boundary with the African plate; the southerly edge is a complex boundary with the Antarctic plate, the Scotia plate, and the Sandwich Plate; the westerly edge is a convergent boundary with the subducting Nazca plate; and the northerly edge is a boundary with the Caribbean plate and the oceanic crust of the North American plate. At the Chile triple junction, near the west coast of the Taitao–Tres Montes Peninsula, an oceanic ridge known as the Chile Rise is actively subducting under the South American plate.

The Barbuda Highlands, referred to locally as The Highlands, are a range of hills located on the island of Barbuda in the Caribbean. It is named after the now-ruined Highland House. The Highlands includes Barbuda's highest point at 44.5 meters above sea level, and the hills are characterized by rocky outcroppings, scrub vegetation, cacti and a unique ecosystem that includes several species of endemic plants and wildlife. The Barbuda Highlands are a protected area, and are recognized for their environmental and geological significance. The highlands have many caves and are located on the Atlantic Ocean.

In France, an overseas collectivity (French: collectivité d'outre-mer, abbreviated as COM) is a first-order administrative division, on the same level as its regions, but have a semi-autonomous status. The COMs include some former French overseas colonies and other overseas entities with a particular status, all of which became COMs by constitutional reform on 28 March 2003. The COMs differ from overseas regions and overseas departments, which have the same status as metropolitan France but are located outside Europe.As integral parts of France, overseas collectivities are represented in the National Assembly, Senate and Economic and Social Council. Though some are outside the European Union, all can vote to elect members of the European Parliament (MEPs). (All of France became one multi-member EU constituency in 2019.) The Pacific COMs use the CFP franc, a currency pegged to the euro, whereas the Atlantic COMs use the euro itself. As of 31 March 2011, there were five COMs:

• French Polynesia became a COM in 2003. Its statutory law of 27 February 2004 gives it the designation of overseas country inside the Republic (French: pays d'outre-mer au sein de la République, or POM), but without legal modification of its status. French Polynesia has a great degree of autonomy, two symbolic manifestations of which are the title of the President of French Polynesia (Le président de la Polynésie française) and its additional designation as a pays d'outre-mer. The legislature is the Assembly of French Polynesia since 2004.
• Saint Barthélemy, an island in the Lesser Antilles. St. Barthelemy was separated from the overseas department of Guadeloupe in 2007. It has a territorial council and executive council, and in 2012 ceased to be part of the European Union.
• Saint Martin, the northern part of the island of Saint Martin in the Lesser Antilles. St. Martin was separated from the overseas department of Guadeloupe in 2007. It has a territorial council and executive council, and with separation remained a part of the European Union.
• Saint Pierre and Miquelon, a group of islands in the Atlantic Ocean off the coast of Newfoundland, Canada. It has a territorial council. It is the last remaining part of New France to be under French rule.
• Wallis and Futuna, three small islands in the Pacific Ocean has a high administrator and territorial assembly.

Lagos (/ˈleɪɡɒs/ LAY-goss; Yoruba: Èkó [èkó]), or Lagos City, is a large metropolitan city in southwestern Nigeria. As of November 2025, the size of the city's population has been estimated to stand between 17 and 21 million residents, making Lagos the largest city in Nigeria, the most populous urban area on the African continent, and one of the fastest-growing megacities in the world. Lagos was the national capital of Nigeria until the government's December 1991 decision to relocate its capital to Abuja, in the centre of the country. Apart from serving as a major African financial center, Lagos has also played a significant role in the national economy, serving as the economic hub of Lagos State and the entire country of Nigeria. The city has a significant influence on commerce, entertainment, technology, education, politics, tourism, art, and fashion in Africa. Lagos is also among the top ten of the world's fastest-growing cities and urban areas. A megacity, it has the second-highest GDP in Africa, and houses one of the largest and busiest seaports on the continent. Due to the large urban population and port traffic volumes, Lagos is classified as a Medium-Port Megacity.

Lagos emerged as a home to the Awori people, an Ijebu subgroup of the Yoruba of West Africa, in the 15th century, which is contained across the present-day Local Government Areas (LGAs) of Lagos Island, Eti-Osa, Amuwo-Odofin, and Apapa. Before the 15th century, the Awori settled on a farmstead along the coastal line, in and around which they worked and lived. Farmstead translates to Ereko in Yoruba, from which comes the Lagos indigenous name Eko. The lands are separated by creeks, fringing the southwest mouth of Lagos Lagoon, while being protected from the Atlantic Ocean by barrier islands and long sand spits such as Bar Beach, which stretch up to 100 km (62 mi) east and west of the mouth. Due to rapid urbanisation, the city expanded to the west of the lagoon to include areas in the present-day Lagos Mainland, Ajeromi-Ifelodun, and Surulere. This led to the classification of Lagos into two main areas: the Island, which was the original city of Lagos, and the Mainland, which it has since expanded into. This city area was governed directly by the Federal Government through the Lagos City Council until the creation of Lagos State in 1967, which led to the splitting of Lagos city into the present-day seven Local Government Areas (LGAs), and the addition of other towns (which now make up 13 LGAs) from the then Western Region to form the state.

Angola, officially the Republic of Angola, is a country on the western coast of Southern Africa. It is the second-largest Portuguese-speaking (Lusophone) country after Brazil in both total area and population and is the seventh-largest country in Africa. It is bordered by Namibia to the south, the Democratic Republic of the Congo to the north, Zambia to the east, and the Atlantic Ocean to the west. Angola has an exclave province, the province of Cabinda, that borders the Republic of the Congo and the Democratic Republic of the Congo. The capital and most populous city is Luanda.

Angola has been inhabited since the Paleolithic Age. After the Bantu expansion reached the region, states were formed by the 13th century and organised into confederations. The Kingdom of Kongo ascended to achieve hegemony among the other kingdoms from the 14th century. Portuguese explorers established relations with Kongo in 1483. To the south were the kingdoms of Ndongo and Matamba, with the Ovimbundu kingdoms further south, and the Mbunda Kingdom in the east.

The Cape Peninsula (Afrikaans: Kaapse Skiereiland) of South Africa is a generally mountainous peninsula that juts out into the Atlantic Ocean at the south-western extremity of the African continent. At the southern end of the peninsula are Cape Point and the Cape of Good Hope. On the northern end is Table Mountain, overlooking Table Bay and the City Bowl of Cape Town, South Africa. The peninsula is 52 km long from Mouille point in the north to Cape Point in the south. The Peninsula has been an island on and off for the past 5 million years, as sea levels fell and rose with the ice age and interglacial global warming cycles of, particularly, the Pleistocene. The last time that the Peninsula was an island was about 1.5 million years ago. Soon afterwards it was joined to the mainland by the emergence from the sea of the sandy area now known as the Cape Flats. The towns and villages of the Cape Peninsula and Cape Flats, and the undeveloped land of the rest of the peninsula now form part of the City of Cape Town metropolitan municipality. The Cape Peninsula is bounded to the north by Table Bay, to the west by the open Atlantic Ocean, and to the east by False Bay in the south and the Cape Flats in the north.

The peninsula is mostly the mountainous remnant of very old durable sandstone formations with low dip, deposited unconformably on an ancient underlying granite peneplain. The climate is of the Mediterranean type, with predominantly winter rainfall and mild temperatures, and the natural vegetation is exceptionally diverse, with an unusually large number of endemic plant species for an area of this size, many of which are endangered, and threatened by human activity and encroachment, but are to some extent protected on the large part of the peninsula which is in Table Mountain National Park. The coastal waters include a major seaport in Table Bay, and a marine protected area in the two adjacent but significantly different marine ecoregions, which meet at Cape Point. Most of the lower lying coastal land of the central and northern peninsula has been developed as first agricultural, and later urban areas. The rocky uplands have historically avoided development because of difficult access, poor soils and steep slopes, and more recently have been legally protected as being of high ecological importance, but are threatened by illegal land invasion and informal settlement.

Guyana, officially the Co-operative Republic of Guyana, is a country on the northern coast of South America, that identifies with the Caribbean and was once part of the historic British West Indies. Georgetown is the capital of Guyana and is also the country's largest city. Guyana is bordered by the Atlantic Ocean to the north, Brazil to the south and southwest, Venezuela to the west, and Suriname to the east.

With a land area of 214,969 km (83,000 sq mi), Guyana is the third-smallest sovereign state by area in mainland South America after Uruguay and Suriname, and is the second-least populous sovereign state in South America after Suriname; it is also one of the least densely populated countries on Earth.

Canada has a vast geography that occupies much of the continent of North America, sharing a land border with the contiguous United States to the south and the US state of Alaska to the northwest. Canada stretches from the Atlantic Ocean in the east to the Pacific Ocean in the west; to the north lies the Arctic Ocean. Greenland is to the northeast with a shared border on Hans Island. To the southeast Canada shares a maritime boundary with France's overseas collectivity of Saint Pierre and Miquelon, the last vestige of New France. By total area (including its waters), Canada is the second-largest country in the world, after Russia. By land area alone, however, Canada ranks fourth, the difference being due to it having the world's largest proportion of fresh water lakes. Of Canada's thirteen provinces and territories, only two are landlocked (Alberta and Saskatchewan) while the other eleven all directly border one of three oceans.

Canada is home to the world's northernmost settlement, Canadian Forces Station Alert, on the northern tip of Ellesmere Island—latitude 82.5°N—which lies 817 kilometres (508 mi) from the North Pole. Much of the Canadian Arctic is covered by ice and permafrost. Canada has the longest coastline in the world, with a total length of 243,042 kilometres (151,019 mi); additionally, its border with the United States is the world's longest land border, stretching 8,891 kilometres (5,525 mi). Three of Canada's Arctic islands, Baffin Island, Victoria Island and Ellesmere Island, are among the ten largest in the world.
