Chii kondinendi uye chii chiri

Pepasi Nyika rinoumbwa mvura uye nenyika. Zvino yakasimba mugove nezvokuvandudzika 29 chete% of zvachose nzvimbo panyika. Uye kunyange kuti dissected nenzizi, nzizi, nehova, migero. Uye vangani varipo pamusoro munyika anezvimiti, madziva uye madhamu - uye haana kuverenga, nekuti vamwe vavo nguva kunyangarika, ipapo dzumbunuka. Zvichida, redu zvaizova zvakarurama kushevedza mvura.

Nyika yose iri rakakamurwa yoga makondinendi. Vanewo kunzi kunyange makondinendi. Chii huru, chii nhoroondo yaro mavambo uye kukura - kwenguva refu yakaramba isingazivikanwi. Nhasi Geological sayenzi inogona kutsanangura zvakawanda, kunyanya, nei makondinendi vari kutamira.

Zvavari vakaita

Huge sedimentary block girenayiti, basalt rukoko akarara anenge 40 makiromita gobvu - ndiko yakaoma. Nhasi, kune kumakondinendi matanhatu, uye vari iri panyika iri gogonera chaizvo, dzikarongwa mu zvakapesana zvePacific venyika. In ayo mamiriro, makondinendi havasi yunifomu. Zvinosanganisira:

• geosynclines (rinopeta munzvimbo);
• platforms (yakadzikama nharaunda).

Kupindura mubvunzo pamusoro izvo yakaoma, tinogona kutaura kuti ichi chakakura nyika guru, lapped nenyanza uye chinosanganisira Mobile uye akatsiga munzvimbo.

Chinjwa zvikamu makondinendi - iri akapeta zvikamu, akawedzera pakureba nezviuru, kana kunyange ezviuru makiromita. Muenzaniso uri ichi inogona Geosynclinal Alpine-eHimalaya bhandi amutambanudzira ari latitudinal mirayiridzo mhiri Eurasia. The kuzorodzwa varehwa shangu makomo nemipata.

Platforms - anononoka-zvinofamba nzvimbo. Ichi mudanga,-refu vakaumba zvikamu pasi goko. Ivo akafukidzwa pamusoro butiro sedimentary yamatombo, izvo mundovanda dzose hadzina kufambiswa zvakanaka renheyo. Panguva dzakadaro, goko paNyika vari mumapani guru. Muenzaniso ndiye East European Plain, riri Russian papuratifomu.

Continental vasakukurwa

Mazuvano pane 6 makondinendi. Remasangano aya ndiwo Eurasia, uye ipapo vakagara zvinotevera kuti: Africa, North America, South America, Antarctica, uye duku - Australia.

Asi zvakanga munhoroondo paNyika imwe nguva apo paiva mumwe chete supercontinent, Pangea, uye iye akavashambidza nemvura penyanza Panthalassa. Chii kondinendi yose Mesozoic yaitonga? Iyi ndiyo nyika hombe, kukura chiri zvakaenzana zvose makondinendi yanhasi vasanganiswa. Pangea wakange wakafukidzwa akasvibira, ramakagadzwa vakasununguka Vaidzungaira dinosaurs. Yakanga umambo hwavo uye maruva nguva.

Makore anenge mamiriyoni 200 apfuura, kondinendi yekare rwakakamukana Laurasia uye Gondwana. Akaumba pakati Tethys Ocean. Laurasia wakasara kuchamhembe hemisphere uye Gondwana kumaodzanyemba akaramba.

Uyewo, izvi zviviri kondinendi yekare pasi jasi fuma kufamba vo rwakakamukana dzakasiyana zvakange kukukurwa kwakasiyana-siyana, zvishoma nezvishoma kutamira kure nomumwe. Ndiwo kuti vemazuva makondinendi, kuti hurukuro iyo vanozivikanwa kwatiri kubva kuchikoro.

Saka, chero yakaoma ano - ndiko chete chaenga pakati Pangea yekare, yaiva kure kare.
