A tropical marine climate is a tropical climate that is primarily influenced by the ocean. It is usually experienced by islands and coastal areas 10° to 20° north and south of the equator. There are two main seasons in a tropical marine climate: the wet season and the dry season. The annual rainfall is 1000 to over 1500 mm (39 to 59 inches).
Many tropical areas have both a dry and a wet season. The wet season, rainy season or green season is the time of year, ranging from one or more months when most of the average annual rainfall in a region falls. [9] Areas with wet seasons are disseminated across portions of the tropics and subtropics, some even in temperate regions. [10]
The entire ocean, containing 97% of Earth's water, spans 70.8% of Earth's surface, [8] making it Earth's global ocean or world ocean. [ 23 ] [ 25 ] This makes Earth, along with its vibrant hydrosphere a "water world" [ 43 ] [ 44 ] or " ocean world ", [ 45 ] [ 46 ] particularly in Earth's early history when the ocean is thought to have possibly ...
The pelagic wandering albatross (Diomedea exulans) ranges over huge areas of ocean and can circle the globe. Hydrophis platurus, the yellow-bellied sea snake, is the only one of the 65 species of marine snakes to spend its entire life in the pelagic zone. It bears live young at sea and is helpless on land.
The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (e.g. the neritic zone), but operationally is often referred to as beginning where the water depths drop to below 200 metres (660 ft), seaward from the coast into the open ocean with its pelagic zone.
The Köppen climate classification is the most widely used climate classification system. [2] It defines a tropical climate as a region where the mean temperature of the coldest month is greater than or equal to 18 °C (64 °F) and does not fit into the criteria for B-group climates, classifying them as an A-group (tropical climate group).

An area of the Amazon rainforest in Brazil. The tropical rainforests of South America contain the largest diversity of species on Earth. [1] [2] Tropical rainforest climate zones (Af). Tropical forests: from the UN FRA2000 report. Tropical rainforests are dense and warm rainforests with high rainfall typically found between 10° north and south ...
Ocean – the four to seven largest named bodies of water in the World Ocean, all of which have "Ocean" in the name (see: Borders of the oceans for details). Sea has several definitions: [a] A division of an ocean, delineated by landforms, [6] currents (e.g., Sargasso Sea), or specific latitude or longitude boundaries. This includes but is not ...
