Tyynimeri eli Tyyni valtameri (eng. Pacific ocean\/the Pacific) on maailman suurin merialue, joka ulottuu pohjoisesta Arktikselta etel\u00e4\u00e4n Antarktikselle ja l\u00e4nnest\u00e4 Aasian ja Australian mantereilta it\u00e4\u00e4n Pohjois- ja Etel\u00e4-Amerikan mantereille.<\/p>\n\n\n\n

Tyyness\u00e4meress\u00e4 on noin 25 000 saarta, joista asuttuja on noin 1 500. Etel\u00e4isen Tyynenmeren valtavaa saaristoaluetta kutsutaan yleisnimell\u00e4 Oseania. Kansainv\u00e4linen p\u00e4iv\u00e4m\u00e4\u00e4r\u00e4raja kulkee Tyynenmeren ja Oseanian poikki.<\/p>\n\n\n\n

Tyynenmeren nimi tulee l\u00f6yt\u00f6retkeilij\u00e4 Fern\u00e3o de Magalh\u00e3esin antamasta latinankielisest\u00e4 nimest\u00e4 Mare Pacificum.<\/p>\n\n\n\n

Tyynenmeren pinta-ala on 165,25 miljoonaa neli\u00f6metri\u00e4. Se peitt\u00e4\u00e4 kolmasosan maan pinnasta ja sen pinta-ala ylitt\u00e4\u00e4 kaiken kuivan maan pinta-alan.<\/p>\n\n\n\n

Tyynenmeren eli\u00f6st\u00f6 on rikkaampi kuin mink\u00e4\u00e4n toisen meren. Pohjoisilla ja etel\u00e4isill\u00e4 alueilla esiintyy muidenkin valtamerien lajeja, ja meren keskiosissa on paljon alkuper\u00e4islajeja. Amerikan rannikkojen kylmiss\u00e4 vesiss\u00e4 kasvaa jopa kolmenkymmenen metrin korkuisia pinnanalaisia lev\u00e4metsi\u00e4. L\u00e4nsiosan l\u00e4mpimiss\u00e4 ja lajirikkaissa vesiss\u00e4 sijaitsevat maailman laajimmat koralliriutat. Tyynell\u00e4merell\u00e4 esiintyy my\u00f6s paljon valaita.<\/p>\n\n\n\n
