Zigwa - ndi chiyani ichi? Tanthauzo ndi kufotokoza kusiyana kwa zigwa otentha

dziko lapansili amakhala makamaka zigwa kugonjetsa phiri osati pa dziko komanso pansi pa madzi.

Chigwacho chiyani?

Plain - ndi ndi lathyathyathya madera akuluakulu a padziko lapansi imene kutalika zigawo pafupi zosiyanasiyana mkati 200 m, ali otsetsereka ofooka (osapitirira 5 m). Chitsanzo kwambiri kusimba m'chigwa tingachipeze powerenga ndi West Siberia Plain: liri ndi zosaoneka pamwamba okwera kusintha omwe ndi pafupifupi imperceptible.

mbali mpumulo

Monga ife kumvetsa tanthauzo pamwamba, m'chigwa - lathyathyathya mtunda ndi pafupifupi lathyathyathya mtunda, popanda Yokwerera zapadera ndi mibadwo, kapena mapiri, ndi alternating ukuwonjezeka yosalala ndi amachepetsa pamwamba.

zigwa lathyathyathya makamaka ali mwa chiwerengero chaching'ono. Iwo zili pafupi ndi nyanja ndi mitsinje yaikulu. Wamba zigwa anagubuduza ndi mtunda m'goli.

Ambiri, kuphwa mtunda amakhala ndi kusintha bwino nyengo chifukwa cha kayendedwe ka zowononga. Kawirikawiri m'madera awo likukwaniritsa kuchuluka kwa mitsinje ndi nyanja komanso kulimbikitsa nyengo. Ena zigwa ndi louma nyengo, m'dera lawo yaikulu imakhala chipululu mosalekeza (Turan m'zigwa, ndi West Australia chikweza).

Zigwa ndi mapiri: kodi pali kusiyana pakati pa iwo

Mosiyana m'Chigwa, mapiri amaimira dziko zikuchepa limatuluka pamwamba pafupi. Iwo yodziwika ndi kusinthasintha kwambiri ya pamwamba ndi phompho zimachititsa chilumbachi. Koma ziwembu yaing'ono lathyathyathya mtunda nawo mu mapiri, pakati ranges phiri. Iwo akutchedwa m'maenje.

Zigwa ndi mapiri - ndi mtundu wa mpumulo, kusiyana kuti zochokera anachokera. Ambiri mwa mapiri inakhazikitsidwa mchikakamizo cha njira tectonic, formations kayendedwe zikuchitika kwambiri matanthwe a pansi padziko. Poyankha, zigwa kugona makamaka pa nsanja - m'madera khola la matanthwe a pansi padziko, iwo akulamuliridwa ndi mphamvu kunja kwa Dziko Lapansi.

Kusiyana pakati pa mapiri ndi zigwa, ndi kusiya maonekedwe a anayambira, tingasiyanitsire:

• pazipita kutalika (Y m'Chigwa akafika 500 m, mu otentha - pamwamba 8 km);
• m'dera (otentha m'dera padziko Lapansi ndi kwambiri wolephera lalikulu m'chigwa);
• Mwina zivomezi (mu zigwa ndi pafupifupi ziro);
• digiri ya chitukuko;
• momwe ntchito munthu.

Zigwa yaikulu

Amazon m'zigwa, yomwe ili ku South America, ndi kukula mu dziko lapansi, malo ake - pafupifupi mamiliyoni 5.2 lalikulu mapazi. Km. Yodziwika ndi osalimba otsika anthu. Yodziwika ndi otentha ndi chinyezi nyengo wandiweyani nkhalango zotentha, ali ndi gawo lalikulu, ndi wodzala nyama, mbalame, tizilombo ndi achule. mitundu ya zinyama a m'dera Amazon ndi pena paliponse.

Kum'mawa kwa Ulaya (Russian) Plain lili kum'mawa kwa Ulaya, malo mamita lalikulu miliyoni 3,9. Km. Ambiri a m'dera zigwa ili mu Russia. Iwo ali dzenje-lathyathyathya mtunda. Pano pali zambiri za m'mizinda ikuluikulu, komanso anaikira ndi chiwerengero chachikulu cha chuma zachilengedwe dziko.

Chapakati Siberia Plateau lili kum'mawa Siberia. Malo - pafupifupi mamiliyoni 3.5 sq. Km.
