title="Linguas indoarias">indoaria</a> falada nas <a href="/wiki/Maldivas" title="Maldivas">Maldivas</a>) atholhu (Dhivehi:އަތޮޅު ). O primeiro rexistro escrito desta palabra é de <a href="/wiki/1625" title="1625">1625</a>. Con todo, o termo foi popularizado por <a href="/wiki/Charles_Darwin" title="Charles Darwin">Charles Darwin</a> (<a href="/wiki/1842" title="1842">1842</a>, p. 2), quen describiu <i>atol</i> como un subconxunto nunha clase especial de illas, cuxa característica distintiva é a presenza dun <a href="/wiki/Arrecife" title="Arrecife">arrecife</a> orgánico. As definicións máis modernas de atol son as de McNeil (<a href="/wiki/1954" title="1954">1954</a>, p. 396): <i>"...un arrecife anular que contén unha lagoa na cal non hai promontorios mais ala de arrecifes e <a href="/w/index.php?title=Illotes&action=edit&redlink=1" class="new" title="Illotes (a páxina aínda non existe)">illotes</a> formados de <a href="/w/index.php?title=Detritos_(biolox%C3%ADa)&action=edit&redlink=1" class="new" title="Detritos (bioloxía) (a páxina aínda non existe)">detritos</a> do arrecife"</i>; e Fairbridge (<a href="/wiki/1950" title="1950">1950</a>, p. 341): <i>"... nun sentido exclusivamente morfolóxico, [como] ... un arrecife de forma anular que inclúe unha lagoa no centro"</i>. </p> <div class="mw-heading mw-heading2"><h2 id="Formación_dun_atol"><span id="Formaci.C3.B3n_dun_atol"></span>Formación dun atol</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Atol&veaction=edit&section=2" title="Editar a sección: «Formación dun atol»" class="mw-editsection-visualeditor"><span>editar</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Atol&action=edit&section=2" title="Editar o código fonte da sección: Formación dun atol"><span>editar a fonte</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-halign-left" typeof="mw:File/Thumb"><a href="/wiki/Ficheiro:Coral_atoll_formation_animation.gif" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/d/d8/Coral_atoll_formation_animation.gif" decoding="async" width="320" height="237" class="mw-file-element" data-file-width="320" data-file-height="237" /></a><figcaption>Animación que mostra o proceso dinámico de formación dun atol coralino. Os corais (representados en púrpura) crecen ao redor dunha illa oceánica, formando un arrecife anular. Cando as condicións son as adecuadas, o arrecife crece, e a illa interior afúndese. Eventualmente a illa desaparece debaixo do nivel da auga, deixando un anel de coral cunha lagoa no seu interior. Este proceso de formación dun atol pode demorarse uns 30 000 000 de anos.</figcaption></figure> <p>Darwin publicou unha explicación da formación de atois de coral no Pacífico Sur (1842) baseada nas observacións feitas durante a súa <a href="/wiki/Segunda_viaxe_do_Beagle" title="Segunda viaxe do Beagle">viaxe de cinco anos</a> a bordo do <a href="/wiki/HMS_Beagle" title="HMS Beagle">HMS Beagle</a>, entre <a href="/wiki/1831" title="1831">1831</a> e <a href="/wiki/1836" title="1836">1836</a>. A súa explicación, que segue sendo aceptada como basicamente correcta, implica a consideración de que varios tipos de illas tropicais -empezando polas illas volcánicas máis elevadas, continuando cos arrecifes de barreira e terminando cos atois- representan unha secuencia de subsidencia (afundimento) gradual do que comezou como un cono volcánico oceánico. Darwin razoou que un arrecife de coral desenvolvido ao redor dunha illa volcánica no océano tropical, crecerá cara a arriba a medida que a illa se afunde, formando tarde ou cedo un grande arrecife coralino, como o representado, por exemplo, por <a href="/wiki/Bora_Bora" class="mw-redirect" title="Bora Bora">Bora Bora</a>. Isto ocorre porque a parte externa do banco se mantén por si mesma próxima ao nivel do mar polo seu crecemento biótico, mentres a parte interior do banco se atrasa no seu crecemento, dando lugar a unha lagoa, porque as condicións no interior son menos favorables para os corais e as algas calcáreas, responsables da maior parte de crecemento do arrecife. Durante ese proceso, a subsidencia leva ao vello volcán a atoparse por baixo do nivel do mar, pero non así aos bancos de coral, que non deixan de crecer mentres a illa se afunde, mantendo a máxima actividade biolóxica onde as condicións lle son óptimas, ao nivel da auga. </p><p>Como os atois son produto do crecemento de organismos mariños tropicais, estas illas só se atopan en augas cálidas nos trópicos. As illas volcánicas situadas máis aló das zonas onde a temperatura da auga é a adecuada para o crecemento dos organismos mariños que forman os corais, afúndense e son erosionadas na superficie. Unha illa que se sitúa onde a temperatura do océano é apenas suficientemente quente para o crecemento do filón ascendente para compensar o afundimento, dise que está no Punto de Darwin. As illas máis polares desenvólvense cara a montañas mariñas ou <a href="/wiki/Guyot" title="Guyot">guyots</a>; as illas máis ecuatoriais desenvólvense cara a atois (por exemplo o <a href="/wiki/Atol_Kure" title="Atol Kure">Atol Kure</a>). </p><p>Reginald Aldworth Daly ofreceu unha explicación algo diferente da formación dun atol: estes serían illas desgastadas pola <a href="/wiki/Erosi%C3%B3n" title="Erosión">erosión</a> (ondas mariñas e correntes oceánicas) durante o último retiro do nivel do mar (ocorrido na <a href="/wiki/Era_glacial" class="mw-redirect" title="Era glacial">era glacial</a>) de aproximadamente 100 metros por baixo do nivel actual do mar, que se desenvolveron como illas coralinas (atois) (ou arrecifes coralinos sobre unha plataforma que rodea unha illa volcánica non completamente desgastada) cando o nivel do mar gradualmente se elevou ao derreterse os <a href="/wiki/Glaciar" title="Glaciar">glaciares</a>. O descubrimento da gran profundidade do remanente volcánico baixo moitos atois, favorece a explicación de Darwin, aínda que poida haber pouca dúbida que a flutuación do nivel do mar tivo unha influencia considerable sobre os atois e outros filóns. </p> <div class="mw-heading mw-heading2"><h2 id="Distribución_e_tamaño"><span id="Distribuci.C3.B3n_e_tama.C3.B1o"></span>Distribución e tamaño</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Atol&veaction=edit&section=3" title="Editar a sección: «Distribución e tamaño»" class="mw-editsection-visualeditor"><span>editar</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Atol&action=edit&section=3" title="Editar o código fonte da sección: Distribución e tamaño"><span>editar a fonte</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/Ficheiro:Mvey0290.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/7/77/Mvey0290.jpg/350px-Mvey0290.jpg" decoding="async" width="350" height="229" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/7/77/Mvey0290.jpg/525px-Mvey0290.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/7/77/Mvey0290.jpg/700px-Mvey0290.jpg 2x" data-file-width="1808" data-file-height="1184" /></a><figcaption>Porción dun atol do <a href="/wiki/Pac%C3%ADfico" class="mw-redirect" title="Pacífico">Pacífico</a>, mostrando dous illotes no anel ou arrecife coralino separadas por un profundo paso entre o océano e a lagoa</figcaption></figure> <p>A maior parte dos principais atois do mundo están no océano Pacífico (con concentracións nas <a href="/wiki/Tuamotu" title="Tuamotu">Illas Tuamotu</a>, <a href="/wiki/Illas_Carolinas" title="Illas Carolinas">Illas Carolinas</a>, <a href="/wiki/Illas_Marshall" title="Illas Marshall">Illas Marshall</a>, <a href="/wiki/Illas_do_Mar_do_Coral" title="Illas do Mar do Coral">Illas do Mar do Coral</a>, e os grupos de illas de <a href="/wiki/Kiribati" title="Kiribati">Kiribati</a> e <a href="/wiki/Tuvalu" title="Tuvalu">Tuvalu</a>) e <a href="/wiki/Oc%C3%A9ano_%C3%8Dndico" title="Océano Índico">océano Índico</a> (os Atois das <a href="/wiki/Maldivas" title="Maldivas">Maldivas</a>, as <a href="/w/index.php?title=Illas_Laccadive&action=edit&redlink=1" class="new" title="Illas Laccadive (a páxina aínda non existe)">Illas Laccadive</a>, o <a href="/wiki/Arquip%C3%A9lago_Chagos" title="Arquipélago Chagos">Arquipélago Chagos</a> e as Illas Externas das <a href="/wiki/Seychelles" title="Seychelles">Seychelles</a>).
