Marajó Archipelago
Marajó Archipelago ('' pt, arquipélago do Marajó'' is the largest fluvial-maritime archipelago on Earth. Located in the states of Amapá and Pará, in Brazil, it is formed by about 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. The aquatic and forming limits of the archipelago are: the Atlantic Ocean (north); the Marajó Bay (east); the Pará River estuary complex (south), and; the Amazon delta (west). Most important islands The largest and most important islands include: *Marajó Island: the largest and most populated of the islands; * Grande de Gurupá Island; * Island of Franco; * Island of Brique; * Island of Fla ...

Mouths Of Amazon Geocover 1990
In animal anatomy, the mouth, also known as the oral cavity, or in Latin cavum oris, is the opening through which many animals take in food and issue vocal sounds. It is also the cavity lying at the upper end of the alimentary canal, bounded on the outside by the lips and inside by the pharynx. In tetrapods, it contains the tongue and, except for some like birds, teeth. This cavity is also known as the buccal cavity, from the Latin ''bucca'' ("cheek"). Some animal phylum, phyla, including arthropods, molluscs and chordates, have a complete digestive system, with a mouth at one end and an anus at the other. Which end forms first in ontogeny is a criterion used to classify bilaterian animals into protostomes and deuterostomes. Development In the first Multicellular organism, multicellular animals, there was probably no mouth or gut and food particles were engulfed by the cells on the exterior surface by a process known as endocytosis. The particles became enclosed in vacuoles in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equator
The equator is a circle of latitude, about in circumference, that divides Earth into the Northern and Southern hemispheres. It is an imaginary line located at 0 degrees latitude, halfway between the North and South poles. The term can also be used for any other celestial body that is roughly spherical. In spatial (3D) geometry, as applied in astronomy, the equator of a rotating spheroid (such as a planet) is the parallel (circle of latitude) at which latitude is defined to be 0°. It is an imaginary line on the spheroid, equidistant from its poles, dividing it into northern and southern hemispheres. In other words, it is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles. On and near the equator (on Earth), noontime sunlight appears almost directly overhead (no more than about 23° from the zenith) every day, year-round. Consequently, the equator has a rather stable daytime temperature throug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caviana
Caviana Meridional, the Ilha Caviana Meridional, is a river island belonging to the Marajó Archipelago, it is located opposite the north coast of Marajó Island in the delta lowlands at the mouth of the Amazon in the state of Pará, Brazil. The island forms part of the low-lying ''marajó várzea'', the inundated land in and around the mouth of the Amazon River. The island is an excellent place to observe the tidal bore called the '' pororoca'', where the Amazon river waters meet the incoming Atlantic tides and form a standing wave In physics, a standing wave, also known as a stationary wave, is a wave that oscillates in time but whose peak amplitude profile does not move in space. The peak amplitude of the wave oscillations at any point in space is constant with respect ..., and is a birdwatchers' haven.

Bailique
Bailique is a district in the Brazilian municipality of Macapá, in the state of Amapá. Bailique is an archipelago of islands in the Amazon River. It consists of eight major islands. The district is limited to the north by the Araguari River, to the south by Canal do Norte, and to the east by the Atlantic Ocean. In 1936, the islands became a district of the capital Macapá. Islands The islands of the archipelago are: * Ilha de Bailique * Ilha do Brigue * Ilha Curuá * Ilha do Faustino * Ilha do Franco * Ilha dos Marinheiros * Igarapé do Meio * Ilha Parazinho, an unhabitated island which nowadays contains Parazinho Biological Reserve. The majority of settlements are rural villages made of stilt houses along the rivers and coast. The infrastructure on the islands is limited. There are several primary schools, and one high school, but there are no clinics, no clean drinking water, and no ferry to the mainland. The archipelago is positioned at a location where different biomes mee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pará River
The Pará River (), also called Parauaú River, Jacaré Grande River, Marajó River Channel, Macacos River Channel, Ribeirão Santa Maria, Santa Maria River Channel and Bocas Bay, is a watercourse and immense Estuary, estuarine complex that functions as a canal between the rivers Amazon River, Amazon (Amazon delta), Tocantins River, Tocantins, Campina Grande (or Pacajá River, Portel Bay) and Marajó Bay, in addition to numerous other smaller rivers. It can also be considered a distributary channel of the Tocantins River. It is located in the state of Pará, Brazil. It presents muddy and turbid waters, rich in sediments originating from its source rivers. Runs for approximately , around the west and south of the island of Marajó. Belém, the state capital of Pará, is located near the south bank of the river. Previously academic research has come to consider this watercourse as a distributary channel of the Amazon River.

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Amazon River
The Amazon River (, ; es, Río Amazonas, pt, Rio Amazonas) in South America is the largest river by discharge volume of water in the world, and the disputed longest river system in the world in comparison to the Nile. The headwaters of the Apurímac River on Nevado Mismi had been considered for nearly a century as the Amazon basin's most distant source, until a 2014 study found it to be the headwaters of the Mantaro River on the Cordillera Rumi Cruz in Peru. The Mantaro and Apurímac rivers join, and with other tributaries form the Ucayali River, which in turn meets the Marañón River upstream of Iquitos, Peru, forming what countries other than Brazil consider to be the main stem of the Amazon. Brazilians call this section the Solimões River above its confluence with the Rio Negro forming what Brazilians call the Amazon at the Meeting of Waters ( pt, Encontro das Águas) at Manaus, the largest city on the river. The Amazon River has an average discharge of about – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as Stream#Creek, creek, Stream#Brook, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to Geographical feature, geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "Burn (landform), burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle.

Marajó
Marajó () is a large coastal island in the state of Pará, Brazil. It is the main and largest of the islands in the Marajó Archipelago. Marajó Island is separated from the mainland by Marajó Bay, Pará River, smaller rivers (especially Macacos and Tajapuru), Companhia River, Jacaré Grande River, Vieira Grande Bay and Atlantic Ocean. From approximately 400 BC to 1600 AD, Marajó was the site of an advanced Pre-Columbian society called the Marajoara culture, which may have numbered more than 100,000 people at its peak. Today, the island is known for its large water buffalo population, as well as the ''pororoca'' tidal bore periodically exhibited by high tides overcoming the usual complex hydrodynamic interactions in the surrounding rivers. It is the second-largest island in South America, and the 35th largest island in the world. With a land area of Marajó is comparable in size to Switzerland. Its maximum span is long and in perpendicular width. Geography Maraj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
