Geography wa United States: nkhani ya boma

United States - dziko yaikulu inali ku North America. dzina dzikoli odziwikiratu, pali mayunitsi loyang'anira limati ogwirizana boma. Geography a United States ndi wapadera chifukwa malo ake pakati pa nyanja ziwiri. Tiyeni tione mwatsatanetsatane dziko.

malo

The US ali kumtunda chapakati North America. Pamafunikanso 48 limati ili mwachindunji ku South America ndi awiri - kunja.

Awa ndi Alaska, yomwe ili kumpoto kwa Africa ndi amene alibe malire ndi boma lenileni, ndipo Hawaii - Islands mu Pacific Ocean.

The United States komanso a ena dera, yomwe ili Caribbean, monga Puerto Rico Islands Virgin US. Komanso zilumba m'dera Pacific Ocean, Alaska. Payokha, ziyenera kuti ku Central Federal District ya Columbia sikuli kwa boma lililonse.

Zikomo kuti malowa chilengedwe US malo ndi nyengo mabacteria ndi yosiyanasiyana.

physiography

Pa gawo la dziko chapadera kwambiri, kapena kani, 5 malo achilengedwe, amene modabwitsa osiyana Chrixitu. Geography wa United States mwachidule ikusonyeza mmene osiyana malo kungakhale dziko chimodzi chokha. Mbali yaikulu ya boma lagawidwa m'zigawo zinayi: kumpoto, Pakati Chakumadzulo, South ndi West.

Choncho, kum'mawa kwa dziko kufupi ndi kugombe la nyanja ya Atlantic, mapiri Appalachian anaphimba. Pali zambiri zosavuta likamalowa zombo Magombe, Gombe ndi otsika ake chidwi ya atsamunda woyamba ku Europe. Kenako anaonekera kwa mzinda waukulu woyamba ku America.

Thupi madera wa United States, makamaka m'chigawo chapakati cha dziko, amakopa alendo kukongola kwa zigwa, yomwe inakhazikitsidwa ndi kuchepetsa kosangalatsa. Komanso, pali yambiri mitsinje, nyanja, zithaphwi ndi mathithi wokongola kwambiri.

Komanso, kumadzulo, malo lili ndi madambo ambiri yokutidwa ndi steppe zomera, wotchedwa mminda. Kudera limeneli zogwirizana kwambiri ulimi. chinyezi mvula zambiri zimathandiza kuti kuswana wa chimanga ndi tirigu pano.

Cordillera - zokwanira mapiri aatali. Mu gawo ili la dziko ali m'mapaki ambiri achilengedwe. Kwachulukanso ndi maphompho, amene chaka anachezeredwa ndi alendo ambiri. Mapiri ali oyenera pafupifupi pafupi kugombe la Pacific Ocean. A Tambasula ka gombe amakopeka ndi nyengo yake subtropical ndi magombe zazikulu.

Mbali kumpoto kwa boma US wa Alaska, yomwe ili pamwamba pa Arctic Circle. A chiwerengero chachikulu cha chilumba ali wotanganidwa ndi mapiri a kumpoto Cordillera. Alaska zovuta mbuye chifukwa cha kuzizira kwambiri.

A nkhani zambiri onani US madera. Kudzachita.

m'dera Appalachian

Tiyeni tione limati ili mu kum'mawa kwa dziko. Iwo zili mu dera kumpoto kum'mawa. Chinthu chidwi ndi kuti iwo anatenga atsamunda choyamba. Okwana pali 10 limafotokoza. Chief pakati pawo - Pennsylvania, New York ndi New Jersey - ndi ambiri kwambiri mu United States. Ine ndiyenera kunena kuti apa wokwatibwa ndi chiwerengero chachikulu kwambiri anthu ochokera amapanga anthu a US. Geography ndi nyengo mikhalidwe m'chigawo ofanana ndi European.

Chifukwa nyengo si ofatsa, ngakhale Atlantic Ocean mwina Kumafeŵetsa mu mapiri wautali ndi ozizira nyengo. Choncho, mu gawo ili la dziko kwambiri anayamba makampani, osati ulimi. Komanso, mu m'dera lamapiri la mchere ambiri. Pamene khala ndi bungwe kupanga ake anatulukira. Kudutsa dziko, migodi kwachititsa chakuti chuma chinayamba mofulumira. Pa nthawi, zintchito zachuma a United States ndi yaikulu ndi zikuphatikizapo anayi osauka malo osiyanasiyana m'chigawo.

Appalachian mapiri kutambasula kwa 1900 Km pamodzi Atlantic gombe ku Maine ku Alabama kum'mwera. Yayikulu kwambiri dongosolo, Phiri Mitchell - mamita oposa 2000. Mu mapiri, mitsinje angapo ochokera: Hudson, analekanitsa Appalachian mapiri kumpoto ndi kumwera, Roanoke, gawani mu theka lokwera kum'mwera kwa Blue Ridge. Ngakhale pamaso pa mitsinje komanso nkhalango, nthaka m'dera limeneli ndi acidic kwambiri, chimene chimafuna oshchelachivanija zonse ndi fetereza.

Atlantic m'mphepete mwa nyanja kumveka

lowland ichi, chimene m'mphepete mwa nyanja ya Atlantic pochoka ku New York kuti ili kum'mwera kwa Florida. malowa ali wofatsa subtropical nyengo. Geography wa United States wopanga kuganiza Sitidzaiwala pa apaulendo, ndi Atlantic m'mphepete mwa nyanja kumveka - imodzi chifukwa chachikulu. Iwo agawidwa magawo angapo.

Mbali ya kumpoto m'chigawo cha New York ku Virginia amakhala ndi foreshore m'goli ndi peninsulas lalikulu ankasiyana Straits cha Long Island ndi Magombe wa New York, Delaware, Albemarle ndi Pamlico. madzi zonsezi yabwino kwa navigation. Ndi gawo ili la chigwa zikuphatikizapo madambo magombe. M'chigawo cha New York ndi mathithi okongola kwambiri dziko - Niagara.

Center ndi kum'mwera

Chigawo chapakati cha m'zigwa ndi ili mu madera a North ndi South Carolina ndi Georgia. mtunda ake ndi mapiri kwambiri. Tsambali kumalo ang'onoang'ono, ndi miyeso awo ang'ono. Pa yalunjika nyanja zisumbu ili wokongola magombe mchenga.

The kum'mwera ndi boma la Florida, yomwe ili pa chilumba chomwecho. Apa pali mapiri ang'onoang'ono ndi bogs lalikulu. South Florida ndi Everglades marshland, izo anasiya mitengo paini zakale kutali ndi steppe udzu mkulu. Izi kawirikawiri subtropical dziko makamaka ili ku mbali ya malo osungirako a dzina lomweli.

Nzosadabwitsa US akalozera kufotokoza dziko - madera, nyengo, chuma, ntchito zokopa alendo - akuyamba ndi boma la Florida.

Gulf m'mphepete mwa nyanja Plain

Gulf m'mphepete mwa nyanja Plain, ili kum'mwera kwa dziko la Alabama ku New Mexico. malire ake - mtsinje Rea Grande. Iwo ubwera monga kumtunda pafupifupi kum'mwera kwa Illinois ndipo chidagawika patatu: kum'mawa, ndi kumadzulo Mississippi. Pagombe ili doko m'mizinda ikuluikulu: New Orleans, Houston ndi Veracruz.

Mu kum'mawa otsika taphunzira ndi mapiri ang'onoang'ono ndi otsika, elongated likufanana ndi kum'mwera kwenikweni kwa Appalachian mapiri. N'zochititsa chidwi akutali kwambiri gombe la m'dera la mapiri Kugwa Line Hills palibe mathithi. Izi Mbali US madera ndi wapadera, chifukwa ambiri ranges phiri lili ndi zambiri cascades madzi. Dera la kumadzulo kwa chigwa ndi ofanana mu dongosolo kum'mawa, choncho lekani malongosoledwe ake sadzatero. Koma gawo pafupi ndi Mississippi, ndi chidwi kwambiri.

Chigwacho wa Mississippi Mtsinje ndi m'lifupi ku 80 160 Km, iwo anapangidwa ndi ledges, lomwe kufika pamwamba mamita 60. Wamphamvu waterway umayenda mumasangalala nawo pa chigwa lonse ndi otsetsereka pang'ono. Ndime wosiyanasiyana amasonyeza bwanji kusintha udindo pa mtsinje. M'madera floodplain ndi lachonde alluvial nthaka. Kuwonjezera apa muli madipoziti kwambiri mafuta ndi gasi. Mu m'dera limeneli, United States madera, chuma ndi zinthu mafakitale amapanga chidwi kwambiri.

zigwa kwambiri

Izi kum'mawa yachonde ya miyala Mountains amadziwika onse. Kutalika kwa malo okwera mamita 700-1800 pamwamba pa nyanja. Pa Wamkulu m'Chigwa anakakhala limati la New Mexico, Nebraska, Texas, Oklahoma, Colorado, Kansas, North ndi South Dakota, Wyoming ndi Montana.

mitsinje onse kuthamanga pa otsetsereka ambiri padziko ina easterly ndi zomwe ziri zogwirizana beseni wa Mississippi ndi Missouri mitsinje. Plateau Missouri waima mbali imodzi lathyathyathya ndi zina - pamwamba pakubwezeretsa, ndi slotted ambirimbiri kwambiri mtsinje zigwa. N'zochititsa chidwi pansi pa zigwa ndi onse kwambiri kuposa mtsinje palokha, ndipo okha ndi ovuta phompho, ataliatali mpaka mamita 30.

Plateau kwambiri wogawanika, m'madera ena chigwa maukonde kwambiri kawirikawiri ntchito ulimi. Kumpoto ndi bedlends, kapena, ngati iwo ali kutchedwa, "m'mayiko zoipa", popanda chivundikiro nthaka. Kum'mwera - Nebraska - phiri Sand Hills. Pa dera la State wa Kansas - mapiri wotsika wautsi Hills ndi mwala Hills ndi zomwe zili Red Hills. Mkulu Valley pafupifupi zosafunika ulimi, koma pali kwambiri kukula tirigu ndipo pali chochuluka odyetserapo ziweto.

mapiri amiyala

Pa mbali ya kumadzulo ya United States akuwatsimikizira Cordillera mapiri, kuyambira ku kumpoto kwa kum'mwera chakum'mawa zitunda kufanana ndi kugawana zitunda zathyathyathya awo, matendawa, ndi zigwa. Motalikitsa mapiri, zimene Ndikufuna osanenapo - ndi miyala m'mapiri. Iwo ali ang'onoang'ono m'dera kuposa Appalachians, koma zochuluka m'dera lokwera, zambiri makolokoto zimachititsa chilumbachi, mitunda zokongola ndi zovuta dongosolo miyala.

Colorado

Mu US, dongosolo la dzikoli, ikulongosola za zintchito za onse mabuku ndi zochitika zachilengedwe a boma. Zikuphatikizapo South ndi miyala Mountains, yomwe ili m'chigawo cha Colorado. Iwo zigwirizana ranges zikuluzikulu phiri mabeseni lalikulu. Limodzi la mapiri apamwamba, Elbert, ufikira mamita 4399. Wokongola, nthawi zambiri chofewa chili pamwamba nsonga, okwera mamita 900 pamwamba malire chapamwamba nkhalango, n'kupanga panorama omveka a mapiri aatali. Pa zobiriwira otsetsereka mitengo tinachokera mitsinje ikuluikulu US - Colorado, Arkansas, Rio Grande.

Mphepete kumadzulo sing'anga mu miyala Mountains ndi seismically yogwira malo. Pali nthawi pali zivomezi. Ndi m'dera limeneli ndi otchuka kwambiri padziko lonse Yellowstone Park.

kugwa mapiri

Kugwa Mountains, yomwe makamaka madera a Oregon ndi Washington, kumlingo, akuchokera chiphala. Chiphalaphala amalenga pamwamba undulating, yatcheredwa ndi zimaphala a mapiri. Yaikulu ya iwo kukwera pamwamba nkhalango, limene lili pamalo okwera mamita 2700.

Nsonga chapamwamba kwambiri mu kugwa Mountains, Rainier, anamasulidwa kulondola ake conical mawonekedwe ndipo ali ndi oundana. Mu malo iyi ili mu Phiri Rainier National Park.

Geography wa United States mwachidule limasonyeza ena kusintha okwera - kuyambira wamng'ono kum'mawa kwa dziko la mamita oposa 4000 kumadzulo - kungakhale pa Africa chomwecho. Apa tikutengegeredwa ku nambala yaikulu masoka achilengedwe mbali zonse m'dzikoli.

California

Pafupi kugwa Mountains zili chimodzi zambiri - Sierra Nevada. Zimapezeka makamaka California. N'zochititsa chidwi izi m'patali mapiri, kukuchitika kwa 640 Km, wapangidwa umangokhala lubwe. m'mphepete kummawa itha mwadzidzidzi waukulu dziwe kusambira, ndi otsetsereka kumadzulo ndi mokoma kusanduka ku Central Valley la California. Kum'mwera kwa wapamwamba ndi bwino pansi pa dzina la High Sierra. Pa nthawi imeneyi, seveni nsonga kuposa mamita 4250 chipale anaphimba. Ndipo Phiri Whitney ndi mamita okwera 4418 - chimbuzi wa United States - ndi makilomita 160 monga ku chigwa cha Imfa.

The phompho otsetsereka a kum'mawa kwa Sierra Nevada mapiri - ndi louma zone zomera ndi kumeneko ndi osauka kwambiri. Pa otsetsereka izi ochepa mitsinje. Koma wofatsa kumadzulo otsetsereka kudula ndi zigwa osawerengeka kwambiri. Ena mwa iwo ndi maphompho wokongola kwambiri, monga wotchuka Yosemite Valley pa Mtsinje Merced mu Yosemite National Park ndi chigwa waukulu kwambiri Mafumu Mtsinje National Park Mafumu Canyon. A mbali yaikulu ya otsetsereka ndi waphimbika nkhalango, ndipo apa kuti kukula sequoias chiphona.

Alaska

A mbali yaikulu ya m'dziko la boma ndi litadzala ndi mapiri anatambasula kuchokera kumadzulo kupita kum'mawa. Mbali kumpoto kwa - ndi lathyathyathya lowland Arctic. Iwo m'mphepete mwa kum'mwera kwa Brooks osiyanasiyana, zimene zinaphatikizapo - De Long Mountains, Endicott, Philip Smith ndi British. Pakati pa boma ndi Yukon yachonde ndi dzina loyenda chomwecho mtsinje. Aleutian manambala ndi yokhota kumapeto mu semicircle pafupi ndi chigwa Susitna Mtsinje napereka mu Alaska osiyanasiyana, kulenga, Choncho, Alaska Peninsula ndi Islands Aleutian pafupi. Ilo liri mu Alaska manambala ndi chimbuzi wa United States - phiri McKinley kutalika mamita 6193.

Alaska - waukulu boma US ndi malo ndi ambiri ang'ono anthu. Malinga ndi kafukufuku, izo ali 736 732 munthu. Pa m'dera la Alaska ndi mapiri yogwira. Chigwa cha nyumba zikwi khumi kumeneko chifukwa cha kuphulika chiphala chamoto, mu 1912. Anthu ambiri a chilumba - mbadwa ya America, komanso Eskimos, Aleuts ndi Amwenye.

Mu US, zintchito za boma ndi mosayembekezera osiyana ndi mzake, izo chidwi la alendo ambiri. Atayendetsa dziko lonse, ndipo mukhoza kupeza chimwene ku Mitundu ina ya mapiri otchuka, maphompho kwambiri ndi wamphamvu mitsinje.
