Yintoni kwilizwekazi kwaye yintoni na

bonke ubuso Umhlaba wenziwe amanzi kunye nomhlaba. Kwaye phezu isabelo okuqinileyo akhawunti ye%-29 kuphela ummandla uwonke wonke umhlaba. Yaye lowo dissected yimilambo, imijelo, imilambo, imijelo. Nokuba bangaphi kukho phezu ezweni imigxobhozo, amachibi kunye namachibi - yaye abazange ukubala, kuba abanye babo amaxesha ngamaxesha shwaka, aphinde avele. Mhlawumbi, iplanethi yethu ibiya kuba echanekileyo ngakumbi ukubiza amanzi.

Lonke ilizwe yahlulwe amazwekazi ezahlukeneyo. Zibizwa kwanoko amazwekazi. Yintoni nemisinga, yintoni na imbali imvelaphi yayo kunye nophuhliso - ixesha elide yaqhubeka iyimfihlelo. Namhlanje inzululwazi yedeskthopi uyakwazi ukuchaza kakhulu, ngokukodwa, kutheni amazwekazi ishukuma.

Izinto zenziwa

Huge sedimentary block zelitye lenyengane, abangelwe umaleko ongqengqe ngumgama oziikhilomitha ezimalunga ne-40 ubukhulu - ukuba nezwe. Namhlanje, kukho kumazwekazi amathandathu, kwaye afumaneka kumphezulu womhlaba lo kolwabelo olungalinganiyo, abahamba ephambene i-Pacific yinxalenye yehlabathi. Kubume bayo, amazwekazi azikho iyunifomu. Ziqulethe:

• geosynclines (alo iindawo);
• amaqonga (indawo izinzile).

Ukuphendula umbuzo malunga nemisinga, sinokuthi oku inobunzima ilizwe elikhulu, akramnceleyo yi ulwandle yaye liqulethe iingingqi mobile kwaye bezinzile.

iindawo ezihambisekayo amazwekazi - isongiwe imimandla, landiswa amawaka ubude, okanye amashumi amawaka eekhilomitha. Umzekelo yale art kunokuba ibhanti Geosynclinal Alpine-zeHimalaya, esukela kwicala latitudinal lonke Eurasia. Inkululeko ivakalise ngokusonga iintaba neentlambo.

Amaqonga - kade-ihamba indawo. Oku esitalini, amacandelo uneemvume elide kolu qweqwe lomhlaba. aba bahamba kunye kwiqweqwe phezulu kumatye awenziwa ludaka, leyo ukufihla zonke izitenxo isiseko. Kumaziko anjalo, kuqweqwe lomhlaba kukho amathafa amakhulu. Umzekelo i East European Plain, apho eqongeni Russian.

drift lizwekazi

Kule mihla kukho 6 amazwekazi. I inkulu kwezi yi- Eurasia, yaye ngoko bahlala kule ndlela ilandelayo: Afrika, North America, Umzantsi Melika, Antarctica, kwaye incinane - Australia.

Kodwa ke kwimbali koMhlaba ngexesha apho kwakukho omnye kuphela supercontinent, Pangea, yaye ahlambe emanzini olwandle Panthalassa. Yintoni na amazwekazi sexesha Mesozoic? Eli lilizwe enkulu, ubukhulu leyo elingana onke amazwekazi zanamhlanje zidityanisiwe. Pangea sahlanganiswa oluchumileyo, phakathi leyo zazizihambela ngokukhululekileyo Dinosaurs. Yaba ebukumkanini babo kunye nexesha kweentyatyambo.

Malunga 200 yezigidi kwiminyaka eyadlulayo, ilizwekazi yamandulo zahlulwe phakathi Laurasia kunye ajenos. Senziwe phakathi Tethys Ocean. Laurasia ababesele kumntla ikhweyitha kunye ajenos emzantsi wahlala.

Kwelinye icala, aba kwilizwekazi yamandulo phantsi intshukumo kweziyobisi yokwaleka kwakhona sahlukana saziinxalenye ezahlukeneyo ezibe ukukhukulisekela kumacala ahlukeneyo, ngokuthe ngcembe ukusuka komnye. Oku yindlela amazwekazi namhlanje, kucacile ezaziwa kuthi evela esikolweni.

Ngenxa yoko, nayiphi ezweni mihla - yinto isiqwengana kuphela ye Pangea yamandulo, eyayikho ngaphambili kude.
