Те участват в строежа на чехлите на повечето от платформите и широко са разпространени в нагънатите структури. На места по границата между камбрия и ордовика се установяват прекъсвания в натрупването на седименти, обусловени от кратковременни морски регресии. Максималното разширение на морските пространства – трансгресии върху платформите – протича през средния ордовик. След това отново настъпва етап на регресии. В относително плитководните епиконтинентални морета, покриващи през периода значителни площи от платформите в Северното полукълбо, се натрупват предимно маломощни (средно до 500 m) варовикови, и в по-малка степен пясъчно-глинести наслаги. В преходните области между платформите и геосинклиналите (в миогеосинклиналните области на Апалачите, Урал и др.) мощността на наслагите нараства (на места до 3000 m), като заедно с варовиковите широко разпространение имат кластичните наслаги. Във вътрешните части на геосинклиналните пояси (евгеосинклиналните зони Магог и Фрейзър в Северна Америка, каледонидите във Великобритания и Казахстан и др.) мощността на ордовишките наслаги достига до 10 000 m. В тези зони са съществували многочислени вулкани и заедно с кластичните наслаги са се натрупали мощни пластове от лави и туфи, а също и силициеви скали. Тук са разпространени както плитководни, така и дълбоководни наслаги. В резултат от проявлението на таконската фаза на тектонски движения в каледонските геосинклинали към края на ордовика са се формирали нагънати структури и са възникнали планински съоръжения. Много учени считат, че през палеозойската ера, в т.ч. и през ордовика, континентите Северна и Южна Америка са били сближени с Европа и Африка, а Австралия се е придвижила към Африка и южната част на Азия. Един от полюсите, най-вероятно, е бил разположен в северния сектор на Тихия океан, а втория в Северна Африка или в съседни райони на Атлантическия океан.<sup id="cite_ref-bse_6-2" class="reference"><a href="#cite_note-bse-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Органичен_свят"><span id=".D0.9E.D1.80.D0.B3.D0.B0.D0.BD.D0.B8.D1.87.D0.B5.D0.BD_.D1.81.D0.B2.D1.8F.D1.82"></span>Органичен свят</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=%D0%9E%D1%80%D0%B4%D0%BE%D0%B2%D0%B8%D0%BA&veaction=edit&section=4" title="Редактиране на раздел: Органичен свят" class="mw-editsection-visualeditor"><span>редактиране</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=%D0%9E%D1%80%D0%B4%D0%BE%D0%B2%D0%B8%D0%BA&action=edit&section=4" title="Edit section's source code: Органичен свят"><span>редактиране на кода</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="Флора"><span id=".D0.A4.D0.BB.D0.BE.D1.80.D0.B0"></span>Флора</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=%D0%9E%D1%80%D0%B4%D0%BE%D0%B2%D0%B8%D0%BA&veaction=edit&section=5" title="Редактиране на раздел: Флора" class="mw-editsection-visualeditor"><span>редактиране</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=%D0%9E%D1%80%D0%B4%D0%BE%D0%B2%D0%B8%D0%BA&action=edit&section=5" title="Edit section's source code: Флора"><span>редактиране на кода</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>През ордовика, както и през камбрия, господствали бактериите.

Във водите на океаните и моретата обитавали планктонни радиоларии и фораминифери. Своя разцвет преживяват граптолитите. По дъното на моретата, в крайбрежните зони и в плитчините живеят многочислени и разнообразни трилобити, брахиоподи, иглокожи, ектопрокти, морски гъби, миди, коремоноги и главоноги мекотели. В топлите морето обитават корали и други ивически коремоноги. С ордовика завършва големия етап от развитието на древния палеозойски органичен свят. В началото на силура измират множество семейства на граптолити, брахиоподи, корали, главоноги мекотели и трилобити, а също и редица своеобразни групи от иглокожи, характерни само за ордовишкия период.<sup id="cite_ref-bse_6-4" class="reference"><a href="#cite_note-bse-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Биогеографско_райониране"><span id=".D0.91.D0.B8.D0.BE.D0.B3.D0.B5.D0.BE.D0.B3.D1.80.D0.B0.D1.84.D1.81.D0.BA.D0.BE_.D1.80.D0.B0.D0.B9.D0.BE.D0.BD.D0.B8.D1.80.D0.B0.D0.BD.D0.B5"></span>Биогеографско райониране</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=%D0%9E%D1%80%D0%B4%D0%BE%D0%B2%D0%B8%D0%BA&veaction=edit&section=7" title="Редактиране на раздел: Биогеографско райониране" class="mw-editsection-visualeditor"><span>редактиране</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=%D0%9E%D1%80%D0%B4%D0%BE%D0%B2%D0%B8%D0%BA&action=edit&section=7" title="Edit section's source code: Биогеографско райониране"><span>редактиране на кода</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>В зависимост от особеностите на разпространението на различни групи на органичния свят през ордовика се обособяват два биогеографски пояса.

Той обхващал Южна Европа, Африка, Южна Азия и вероятно Австралия и Южна Америка. Органичният свят в този пояс се отличавал със своя беден органичен свят.
