The Amazon River is the largest river in the world in terms of its flow rate. In addition, it is the second longest river, measuring 6,575 km (4,086 mi) [3] from its source to the mouth of the Atlantic Ocean [4] after the Nile River which is considered to be the longest river in the world (see Source of the Nile River), although there is some dispute.

The continental shelf is relatively smooth and shallow, with a drop on the shelf about half-way to the north. The deepest point is −2,047 metres (−6,716 ft), and the average is −49 metres (−161 ft).
The Pororoca (Portuguese pronunciation: [pɔɾɔˈɾɔkɐ], [poɾoˈɾɔkɐ]) is a tidal bore, with waves up to 4 m (13 ft) high that travel as much as 800 km (500 mi) inland upstream on the Amazon River and adjacent rivers. Its name might come from the indigenous Tupi language, where it could translate into "great roar".
