Umzantsi Melika: isiqabu, lasungulwa nowangoku namathafa

Ekhethekileyo kubume bayo zejoloji na, ngaphandle kokukhetha, onke amazwekazi kwiplanethi yethu, kuquka noMzantsi Merika. Isiqabu le ndawo yahlulwe kabini: weentaba kwaye iflethi, kunye misinga ezinkulu. Ngenxa kule isakhiwo noqweqwe , eli lizwekazi liye laba amadlelo aluhlaza kule planethi kunye kakhulu olumanzi, kodwa ngaxeshanye kunye kumahlathi ashinyeneyo apha kukho ke iintili entlango kakhulu eziyimiqwebedu neencopho likhephu ezigqunywe ziphezulu kakhulu. Kaloku, makhe siqwalasele ngokweenkcukacha oko ngengingqi e Umzantsi Melika nendlela esinceda ngayo imozulu ndawo.

Ngokwakhiwa komhlaba neziseko zayo

Yinto eyaziwayo ukuba isiseko zonke mhlaba emhlabeni babumba amacwecwe lithosfere. Kwezinye iindawo, ukuba diverge, ngaloo ndlela bakha ukudakumba. Ngamanye zinonxibelelwano, akha iintaba neenduli. Le meko ayikho ngaphandle, and South America. lizwekazi Uncedo lungohlulwa lube eMpuma West. Eyokuqala zivezwa iintaba ezintlanjeni owomileyo, owesibini - imimandla sethafa okuqhubekayo esesihlanjeni.

Izizathu lo mahluko zezi amabali emhlabeni ukwakhiwa. Inxalenye nempuma yeli lizwekazi yi kwiqonga tyaba endala iqinile. Inxalenye lasentshonalanga ibekwe kwindawo ekuhlangana amacwecwe elizwekazi lothuli abasafuna kufana ukutyhala omnye. Ngokusebenzisa le nkqubo, bakha kwaye bayaqhubeka ukwenza i Andes - emide entabeni uluhlu ehlabathini. Oku kunokwenziwa isigqibo sokuba isiqabu yoMzantsi Melika ngecala lasentshonalanga usenziwa ukuza kuthi ga ngoku. Iintaba ngokuqhubekayo liphuma komhlaba kunye neenkqubo mlilo musa kupheza.

East, nethafa layo

Le ndawo nokwakheka ithatha inxalenye enkulu lwase Umzantsi Melika. Inkululeko apha, njengoko natshoyo, kwasekwa ezigidi zeminyaka eyadlulayo, yaye ngoku yena ngokuqinileyo epleyitini enye lithospheric, nto leyo seismically izinzile. Ngokubanzi, empuma kwelizwekazi yahlulwe ezintandathu. Inxalenye enkulu kummandla awayephantsi Brazil kunye esezintabeni Guiana. Bona elise iiplanga amacwecwe South American. On iipleyiti nabo emathafeni ezintathu: La Plata, Amazon Orinoco. Icandelo isiqabu Last - Patagonia. Le mathafa step, nephakame kubude ka-2000 m. Oku ibekwe emzantsi-mpuma lizwekazi, kummandla ka-Argentina.

Imozulu kumathafa zasempumalanga

Zomhlaba of South America kule kwinxalenye esempuma abantu abanjalo ukuba akukho iintaba okanye iinduli eziphakamileyo. Ngenxa yokuba umoya iinkanyamba ukusuka Atlantic ndzulu ngokukhululekileyo kulo ilizwe, ukunkcenkceshelwa imvula, ukuba umnike inkungu, neengqimba zamafu.

Ngaphezu kule ndawo yi ariya ephantsi-ingcinezelo, nto leyo 'ondle' imimoya kurhwebo Atlantic. Ngenxa yoko, inani ke owayo imvula ehlabathini. Enkosi kubo, Amazon umlambo ukhuko, emlanjeni sikhulu ehlabathini, zizele ezantsi emathunjini omhlaba. Yaye singqongwe kumahlathi nezangaphakathi emvula umiwe kwezihlahla ezizodwa.

Ubume bale West

Le nxalenye zwekazi elimxinwa kakhulu, kwaye ngexesha elinye ngathi nangengalo ukusuka emantla ukuya emazantsi. Yena nangoku luyasekwa, ngenxa yokuba phantse apha qho ngonyaka, Iinyikima, kwaye qho emva kweminyaka 10-15 mlilo qhuma. Apha, isiqabu kwelizwekazi yoMzantsi Melika lungahlulwa-hlulwa ibe iinxalenye ezimbini: iintaba Andes kunye emazibukweni Atacama kwintlango. Iyalibala lebanga-9000 km - nto iyeyona inde ehlabathini. Ingongoma inkulu Mount Aconcagua, ukuphakama kwayo - 6962 eemitha. Le lebanga a yomlambo nje kuphela, kodwa asisithintelo iinkanyamba wePasifiki. imimoya ebandayo evela kwemisinga Antarctic kucanda apha, ukufikelela kuphela iinduli Atacama, bekungayi nzulu kweli lizwekazi.

data zezulu

Andes ukulidla kunxweme olusentshona lonke lwase Umzantsi Melika. Lo mmandla uwahlule ube zahlulo zithathu: North, Centre kunye noMzantsi. Eyokuqala kwezi umanzi - apha ke ubuncinane enamandla esesibhakabhakeni. maxa wambi imvula yonyaka ifikelela 7,000 mm, lo gama i-avareji - 4000 mm. Inxalenye phakathi Andes kakhulu ububanzi (ukuya kuma-500 km), kwaye ke xi kancane. Isixa kwemvula ngonyaka - ukuya ku-1500 mm, maxa wambi imbalela kwi-500 mm. Lobushushu lehla njenge libukhali kwi unyawo, kwaye endaweni ka iibhanti eziphakamileyo. Oku kungenxa yokuba kufuphi kukho Atacama - kwintlango kakhulu eliyinkqantosi ehlabathini. Kwezinye iindawo imvula nenkungu ukuba sele engama-400 ubudala. Southern Andes lawona. umahluko lobushushu eliphezulu apha, yaye ngamanye amaxesha degrees 40. Umbilo - 250 mm.

Ekumeni Umzantsi Melika

Isakhiwo wejoloji nayiphi elizwekazi ngokubanzi imisela enezityalo nezilwanyana zayo, idala kwinkangeleko. Zezwe ukuba sikwazi ukufumana eMzantsi Merika, ngendlela emangalisayo ezahlukeneyo, kwaye ngexesha elifanayo zonke iimbombo yeli lizwekazi iyodwa kuba ubuhle ayikho enye ezinjalo akasekho.

Ngoko ke, lo kwimpuma, nto leyo uhlanjiweyo yi-Atlantic Ocean - lolwandle kakuhle izidanga. Ngokuthe ngcembe, aye kwiinduli ezincinane (a umzekelo eqhelekileyo - Rio de Janeiro). Kwezinye iindawo lizwekazi ngokupheleleyo ntlango tyaba (Buenos Aires). Xa iziko yenqanaba ilizwekazi lifinyele, okwenza ukuba ukuyilwa kwindawo enehlathi kunye nemilambo ezininzi. Le jungle odumileyo eMzantsi Melika kunye Amazon. West ivela njenge iintaba ezinde wambu ikhephu kunye ezihambayo ongatshiyo. Kufuphi emdeni Pacific Ocean ukuya kungena ezindulini, apho umhlaba ngokoqobo aqhekekileyo ukusuka kwiminyaka yimbalela. eyingozi apha rhoqo ngokubomvu wengxondorha, nto leyo entwasahlobo zigqunywe imifuno kunye neentyatyambo, yaye ethubeni ehlotyeni ibe kwintlango umoya.

iziphumo

Sele sithethe, oko kukuthi, isiqabu yoMzantsi Merika. Grade 7 - ixesha xa abantwana befunda ngokweenkcukacha isakhiwo amazwekazi ezahlukeneyo iplanethi yethu. Ukuze baye bafunda izinto, ukunika umzekeliso kakuhle kwecandelo ngalunye lizwekazi, ukuze ubuchopho sasikwazi ukunxulumana ulwazi jikelele kunye imifanekiso ebonakalayo.
