Amapá in the context of "Coastline of Brazil"

The Amazon Delta (Portuguese: delta do Amazonas) is a vast river delta formed by the Amazon River and the Tocantins River (through the Pará River distributary channel) in northern South America. It is located in the Brazilian states of Amapá and Pará and encompasses the Marajó Archipelago, with Marajó Island as its largest island. The main cities located in the vicinity are Belém and Macapá, each with its respective metropolitan area.

The Amazon Delta has a tropical climate with high humidity and high temperatures. It has a wet season with frequent flooding and a dry season where the delta dries out. These seasons shape the environment of the Amazon Delta and the life in it, such as the water buffalo for which Marajó Island is well known, three-toed sloth, capybara, giant anteater, giant otter, jaguar and pink river dolphins.

The Oyapock or Oiapoque (/ˈɔɪ.əpɒk, ˌɔɪ.əˈpoʊki/ OY-ə-pok, OY-ə-POH-kee; French: Fleuve Oyapock [flœv ojapɔk]; Portuguese: Rio Oiapoque [ˈʁi.u ojaˈpɔki]) is a 403-kilometre (250 mi) long river in South America that forms most of the border between the French overseas department of French Guiana and the Brazilian state of Amapá.

Pará (Brazilian Portuguese: [paˈɾa] ) is a state of Brazil, located in northern Brazil and traversed by the lower Amazon River. It borders the Brazilian states of Amapá, Maranhão, Tocantins, Mato Grosso, Amazonas and Roraima. To the northwest are the borders of Guyana and Suriname, to the northeast of Pará is the Atlantic Ocean. The capital and largest city is Belém, which is located at the Marajó bay, near the estuary of the Amazon river. The state, which is home to 4.1% of the Brazilian population, is responsible for just 2.2% of the Brazilian GDP.

Pará is the most populous state of the North Region, with a population of over 8.6 million, being the ninth-most populous state in Brazil. It is the second-largest state of Brazil in area, at 1.2 million square kilometres (460,000 sq mi), second only to Amazonas upriver. Its most famous icons are the Amazon River and the Amazon rainforest. Pará produces rubber (extracted from rubber tree groves), cassava, açaí, pineapple, cocoa, black pepper, coconut, banana, tropical hardwoods such as mahogany, and minerals such as iron ore and bauxite. A new commodity crop is soy, cultivated in the region of Santarém.

The Marajó Archipelago (Portuguese: arquipélago do Marajó) is the largest fluvial-maritime archipelago on Earth. Located in the Brazilian states of Amapá and Pará, the island group has approx. 2,500 islands.

The main island of the archipelago also has the name of Marajó, having about 42,000 km² of area, considered, due to its size, as the largest coastal island in Brazil, extending from the mouth of the Amazon River, between the Line of the Equator and the parallel 1.55º south latitude and, in the E/W direction between the meridians 47º and 53º west longitude, until the Atlantic Ocean.

Macapá (Brazilian Portuguese pronunciation: [makaˈpa] ) is a city in Brazil with a population of 512,902 (2020 estimate), and is the capital of Amapá state in the country's North Region, located on the northern channel of the Amazon Delta near its mouth on the Atlantic Ocean. The city is on a small plateau on the Amazon in the southeast of the state of Amapá. The only access by road from outside the province is from the overseas French department of French Guiana, although there are regular ferries to Belém, Brazil. Macapá is linked by road with some other cities in Amapá. The equator runs through the middle of the city, leading residents to refer to Macapá as "The capital of the middle of the world." It covers 6,407.12 square kilometres (2,473.80 sq mi) and is located northwest of the large inland island of Marajó and south of the border with French Guiana.
