Amkati njira - mpweya otentha a dziko

zochitika zonse za nthaka zikuchitika pa dziko lathuli ndi kupanga zimachititsa chilumbachi ake ndi maonekedwe, ndi m'magulu awiri: exogenous ndipo amkati njira. Yoyamba, kutsogolera ntchito yake padziko mpumulo, ndi weathering zotsatira za misa osiyana madzi (mumlengalenga, pansi, kuwundana, nyanja, nyanja, etc.). njira amenewa amangoona uthunthu flaccid ndipo iwo amabwera chifukwa cha chikoka cha mphamvu dzuwa, yokoka, ndi ntchito Dziko Lapansi yofunika zamoyo.

njira amkati mofulumira kwambiri ndi digiri kwambiri chosintha nkhope ya dziko lapansi. Waukulu Geological njira amkati mwachilengedwe zinthu amphamvu monga ntchito chiphala gululi mbale tectonic ndi zivomezi. Ali akuthandiza kwambiri pa ntchito lonse chuma cha munthuyo ndi kusintha kwenikweni mu dongosolo lathuli zachilengedwe. Kuphulika kwa mapiri ndi zivomezi, monga mbali mawonetseredwe kudya a magulu a mkati mwa Lapansi, nthawi zambiri zoopsa.

njira amkati kupanga maonekedwe a dziko lathuli, pokweza ndi kutsitsa m'madera osiyanasiyana a padziko lapansi. Choncho, nawonso megaformy ndi macroforms mapulaneti mtunda. Ndi chifukwa amkati yothandiza n'kupanga magulu padziko lathuli anatuluka mapiri ndi zigwa lalikulu, maphompho yaikulu ndiponso ngalande zikuluzikulu. m'maiko lonse ndi zilumba ngongole kubadwa kwawo lamkati mphamvu za dziko lapansi, amene ntchito ndipo ankatchedwa "njira amkati."

Choncho, nthaka dziko lonse lapansi, umene ndi mapangidwe ndi chitukuko cha chipolopolo lithospheric, komanso mapangidwe mpumulo pamwamba mbiri yakale ya dziko ndi zotsatira za mogwirizana mitundu iwiri ya mphamvu - exogenous ndipo amkati. The chidwi kwambiri ndi mawonetseredwe loyamba kuphulitsa mapiri zivomezi, umapatsa nyonga pakati padziko lapansi ndi kutentha mkati mwa zigawo madzi a dziko.

Amkati njira miyala imapanga mkati lingamutsatire mphamvu Earth, amene kumaonekera zoyenda lithospheric mbale mayina chobvala mu zigawo chapamwamba za lithosphere kenako padziko effusion wake. njira amenewa amabwera chifukwa cha yunifolomu kufalitsidwa achitsulo padziko phata, kumene pambali mapangidwe mpumulo, amachita mbali ina yofunika - amapanga munda lathuli maginito, potero kupanga chishango chodalirika ndi cheza woopsa dzuwa.

Chotero njira amkati chifukwa kayendedwe ka lithosphere, amene nawonso kumathandiza kuti kusamuka kwa dongosolo lalikulu thanthwe. Izo zonse amasintha kapangidwe ka zigawo chapamwamba kutumphuka padziko lapansi ndi moyenera, pamwamba zimachititsa chilumbachi.

Tsopano, ngati mabiliyoni zaka zapitazo, dziko geologically yogwira. Munganene kuti tinali amwayi zokwanira kukhala mu nthawi ya maluwa a dziko Geological. Ndipo wodabwitsa mkati mphamvu subsoil pamodzi ndi kuwonongedwa ndi masoka moyo, kupanga, kuyamba ndi kulimbikitsa chitetezo zonse zachilengedwe. Koma nthawi. Tsiku lina kutentha pakati Dziko Lapansi iyamba kugwera ndi kuti kuchepetsa ndondomeko ya convection. Izi zikuphatikizapo kuletsa njira amkati. Zotsatira za amasiya ichi - kutha kwa moyo pa dziko ...
