Ndi angati nyanja pa Dziko Lapansi: kutsutsana za chiwerengero chenicheni

Favorite funso la mphunzitsi madera: "Kodi nyanja ambiri Padziko Lapansi kulibe" Yankho Pankhaniyi angakhale osiyana, kumvetsa mwatsatanetsatane za Kapangidwe ka hydrosphere la dziko lathuli. Madzi chipolopolo - ndicho chinsinsi moyo ndi chitukuko m'dziko lapansi, kotero aliyense ayenera kukhala osachepera chabe yodziwa njira zimene zimachitika mmenemo. Pa izi ndi zina zambiri zosangalatsa mfundo za hydrosphere akukamba m'nkhani ino.

Pambuyo kuonerera yaitali asayansi padziko lonse afike pomvetsetsa kuti funso la kuchuluka kwa nyanja pa dziko lapansi lilipo, yankho ndi wopezeka - anayi. Ngati ife titembenukira kwa mbiri ya kafukufuku wa hydrosphere, inu adzaona kuti poyamba linatsegulidwa Indian Ocean. Iye amawaona kuti otchulidwa pa Dziko Lapansi, chifukwa m'chilimwe madzi pafupi gombe akhoza kusangalatsidwa ndi mbiri 35 ° C kutentha.

Titayenda ulendo Hristofora Kolumba, amene anali kuyesera kupeza njira kwa India - wokongola kwa Ulaya pa nthawi imeneyo dziko - anthu aphunzira zokhudza latsopano lalikulu madzi m'thupi. Polemekeza titan Greek Atlas, amene nthano wapereka mtima lakuthwa, kulimba mtima, nyanja anapatsidwa dzina la Atlantic. Thupi madzi cholakwika kwathunthu poyerekeza ndi nthano ya ngwazi, chifukwa iye akhoza zinthu kwathunthu unpredictably mu nyengo zosiyana.

Kodi nyanja ambiri Padziko Lapansi panobe? Pakati kale akamuuze anali ziwiri: Pacific ndi Arctic. Pacific, ndipotu nalo dzina lake ndi kulakwitsa, chifukwa pa ulendo dziko la oyendetsa sitima zazikulu Magellan mwayi kwambiri ndi nyengo. Choncho, kafukufuku ankaganiza kuti nyanja ali ndi mtima wodekha, koma si choncho. Pa chakumadzulo kwa gombe la North America ndi kuzungulira zisumbu Japanese kawirikawiri tsunami.

Arctic Ocean - ndi wa bata la matupi yaikulu ya madzi pa dziko lathuli, komanso ozizira kwambiri. madzi ake sali nsomba zambiri ndi zomera, chifukwa si onse a nyama ndi zomera chingathe kupirira mavuto a moyo mu izo.

Panali nthawi asayansi ena pa funsoli: "Kodi zambiri za m'nyanja onse pa Dziko Lapansi" - anayankha kuti: "zisanu." Atachira chimodzi kwambiri madzi, omwe amatsuka kugombe la Antarctica. Iye anapatsidwa dzina la South, koma malire a wake ndi yosokoneza kuti pa nthawi drafters mapu ndi salinso potanthauza nyanja.

Ndi zodziwika mmene nyanja Padziko Lapansi. Ambiri danga asayansi amakhulupirira kuti hydrosphere akanakhoza kukhala pa maplaneti ena a dongosolo la zowalitsa. Mwachitsanzo, asayansi padziko lonse akufunsa, "nyanja angati pa dziko Mars analipodi?" Iwo anati, silinakwaniritsidwe anapeza, koma ngati hydrosphere akali pamenepo, ndi mamilioni mwina wa zaka zapitazo komanso anali pa dziko loyandikana kukhala zamoyo.

M'nyanja kupanga padziko lathuli unyolo mosalekeza, mbali ya amene ali pamwamba matupi madzi. Iye ndiye gwero la moyo, choncho anthu ayenera kuteteza gwero ndi ofunika kwambiri monga madzi oyera. Ndi kugawa bwino za malo amenewa, anthu eni sitingakumane ndi moyo wabwinobwino, komanso kuchepetsa mosavuta masoka osiyanasiyana achilengedwe.
