Kuyini iqhwa? Inkinga ikuphi-ingabe futhi uyini iqhwa?

Isikhathi ngasinye kanye ukufika ebusika kanye kweqhwa sibhekene uhlobo oluthile kokubheduka ngokomzwelo. ingubo emhlophe asibekela idolobha, amahlathi emvula aminyene futhi o-Ashera, amasimu engapheli nemifula ububanzi, futhi izihlahla ukuze qedani e anombala ocwazimulayo yinqaba elangeni izingubo, ngeke abashiye nandaba noma iyiphi ingane noma umuntu omdala. Ngiseyingane asikwazanga ukuhlala amahora ngu iwindi futhi ubukele njengoba, ukujikeleza kancane fly esidlule Snowflakes iwe kancane emhlabathini ... ngokuvamile Siye sacabangela isakhiwo, uzama ukuthola ezimbili ezifanayo, namanje kusimangaze ubuhle nokuba yinkimbinkimbi lokhu ubukhazikhazi imilingo.

Snowy ebusika njalo igcwalisa umphefumulo kwengane umuzwa nokujabula ofuna ukuphumela obala. Ngokuhamba kwesikhathi, lapho ingane ikhula, umuzwa is abathuntubezwe, kodwa namanje ndawo ndawo inhliziyo yami yonke izitobhi, futhi sijabulela ubuhle elele ngaphansi umgubuzelo white bemvelo. Izingane ngokuvamile abazali bazo: "Kuyini iqhwa?" Abadala ngokuvamile basabela e monosyllables, ethi ukuthi amanzi simisiwe. Kulesi sihloko sizozama ukuthola hhayi kuphela umbuzo uyini iqhwa, kodwa futhi sibheke impahla yayo, kokubili ku ingxenye isayensi, futhi izinkondlo.

Okushiwo ngabantu encyclopedia?

Dictionary Dahl sika esewuphendula kuyini iqhwa, ngendlela elandelayo: kuba eqandisiwe, umhwamuko, ewa ngesimo ishq, bube manikiniki phakathi kwamafu; ice okuxekethile ukuthi ubuyisela imvula ebusika. Njengoba ubona, incazelo kuyinto ngempela okuncane. Zonke-ukwazi Wikipedia, laconic kakhulu, lithi iqhwa - kuwuhlobo kwezulu ukuthi siqukethe zinhlayiya ezincane ice. Collegiate Dictionary ibika okulandelayo: iqhwa okuqinile kwezulu, okuyinto akhiwa ice zinhlayiya, ezingafani ukuma ezahlukene; eqhwa ngokuvamile athathe isimo amapuleti olunezinhlangothi noma izinkanyezi; udedele, lapho izinga lokushisa lehla ngezansi zero degrees Celsius. It kuvela ukuthi yonke izichazamazwi nama-encyclopedia ukusho into efanayo, kodwa ukucacisa ngalolu yini iqhwa, abazi neqhaza. Kulokhu, ubheke sciences ngqo.

Imininingwane zomlando

Inkinga ikuphi-ingabe iqhwa? Of kuthini aqukethe? Kuyini lokushisa yayo? Lezi nezinye izinkinga eziningi ezihlobene nale Isenzakalo esingokwemvelo, ososayensi emhlabeni wonke unesithakazelo isikhathi eside. Ngakho, ngo-1611 i-ngezinkanyezi futhi sezinkanyezi Kepler eshicilelwe indatshana lwesayensi, unelungelo, "On the ishq olunezinhlangothi." Umbhali is pragmatic kakhulu wafunda iqhwa zinhlayiya nge okukhulu konke okusemandleni geometry. Umsebenzi wakhe kwakheka isisekelo isayensi ezinjalo, njengoba crystallography theory. Enye owaziwayo kwekhulu nesikhombisa, sezibalo French sefilosofi Rene Dekart, ukuthi uyathinteka ekutadisheni eqhwa fomu. Wabhala endaweni 1635 cwaningo, esagcina kufakwe umsebenzi "Experience izinkanyezi ezitshuzayo." Esikhathini esizayo, umbuzo yini eqhweni, kubhekwa ososayensi emhlabeni izikhathi emhlabeni ezingenakubalwa.

Futhi basahlola ukuthi lokhu mkhuba ososayensi zanamuhla?

Namuhla, ngisho enkulisa izingane bathi eqhwa zime njengamashubhu hexagon ukuthi umklamo wabo uhlukile futhi akukho eqhwa ezifanayo. Kunengqondo ukuphetha ngokuthi yonke into aziwayo kakade: izinga lokushisa lapho iqhwa liyancibilika, into, nokunye okuningi. Futhi okwamanje ososayensi awalulahlanga nentshisekelo lesi simangaliso bemvelo namanje ukutadisha izinqubo kumiswa zamakhekheba eqhwa. It kuvela ukuthi akhiwa emhlabeni okuthiwa crystallisation nuclei, futhi, kakhulu kuyathakazelisa, angase izinhlayiya ngomzuzu ngothuli, umule, impova, ngisho ezinhlamvu.

izinga iqhwa, ukunconywa izimbongi

Creaking - Lena ukusebenza ezithakazelisayo. Yena ungezwakala kuphela kubanda kakhulu. Ngakho, uma uyokuma usuku kuqhathaniswa efudumele, iqhwa nizothula. Futhi ngendlela ehluke ukuthi iziphatha ngesikhathi samanje abandayo ebusika. Sekuyisikhathi eside abantu waphawula: the ephansi iqhwa lokushisa emoyeni, ayanda ntswininiza phezulu. Ososayensi bakwazi nithole ukuthi lo mphumela kwenzeka ngenxa kwasani ezincane ice zinhlayiya. Lapho izinga lokushisa iqhwa lehliselwa, lezi zinhlayiya babe ziyaqothuka kakhulu futhi kunzima, ngakho wenze umsindo creaking, breaking ngaphansi amasondo izimoto kwezinyawo zethu. Uma akuqede eyodwa crystal ezinjalo, singezwa, ngenxa yobukhulu balo encane. Ezinjalo ezicashile umsindo endlebeni yomuntu akakwazi ukubamba. Kodwa ndawonye, zinhlayiya bayakwazi ukudala i umculo wangemuva ezehlukile. Lokhu creaking kakhulu futhi bacule izimbongi emisebenzini yabo.

Kungani iqhwa noma imvula?

Inzika elihlobene ne uquqaba disequilibrium (ukuzinza) ifu okuyinto aqukethe sebuningini izakhi kwezinhlaka ezahlukene nosayizi. I iyunifomu ngaphezulu isakhiwo, kulapho esitebeleni efwini, futhi, ngokufanelekile, isikhathi eside ngeke imali. Ngayiphi ifomu kokuba afinyelele phansi, incike lokushisa mass emoyeni podoblachnom ungqimba, kanye ukuphakama kanye nesakhiwo efwini (ngokuvamile ke ixubene, isb yakhiwa amaconsi amanzi chilled futhi ice zinhlayiya). Sizokwenza ukuqonda ukuthi lokhu kusho. Falling kulelo fu, ingxube maqondana ebusweni iplanethi sidlula podoblachnye mass. Uma izinga lokushisa kulokhu sezingeni eliphezulu, zinhlayiya ice ancibilike futhi siguqulelwa imvula evamile nge omuhle lokushisa amaconsi. Ngezinye izikhathi, uma ongaphakeme engamamitha amafu, amakhekheba eqhwa angase angabi naso isikhathi sokupheka ancibilike ngokuphelele, kulesi simo, iqhwa ezimanzi uwela. Yingakho kule off-inkathi ungawela kwezulu okuxubile. Uma podoblachnoy mass lokushisa alivumi, ke iqhwa kulula.

Kungani-ke ngezinye izikhathi snows ehlobo nemvula ebusika?

Sesihlole, ngasiphi lokushisa it is nesithwathwa, kodwa ngasiphi - imvula. Nokho, ngezinye izikhathi zikhona izenzakalo okungavamile, ezifana iqhwa ehlobo ungawela, futhi ebusika - imvula. Kuchazwa kanjani-ke cataclysms ezinjalo? Ake sizame ukuqonda ukuthi kungani lokhu kwenzeka. Ososayensi ukuchaza lesi simo sibangelwa ukuphambuka enkambweni ejwayelekile izinqubo ukuthuthukiswa emkhathini. Ngakho, ebusika zindawo maphakathi mass ungase uthole umswakama-ocebile emoyeni ngempela efudumele babesuka amachibi nezilwandle eningizimu efudumele. Ngenxa uma kuncibilika iqhwa liqala, okuyinto azibonakalisa ukuncibilika iqhwa kwezulu ngesimo imvula. Ehlobo, singakwazi ukugcina isimo okuphambene, ukuthi eningizimu ebandayo hleze wavele emoyeni uquqaba kusukela e-Arctic. Phakathi ukubaleka bengaphambili efudumele kwakhiwa cloudiness enamandla kakhulu, ku kwesigaba imigqa ukugudluka ezimbili emoyeni nge ezahlukene okushisa kwezulu ayinala kakhulu. Okokuqala, ngesimo imvula, futhi eminye, ngesikhathi Ukupholisa eyalandela enikeziwe ifu ongaphakeme ngesimo iqhwa elula noma ezimanzi. Ezindaweni eningizimu, kuyaqabukela kunjalo, ngenkathi lokushisa kwamanzi umhlaba usalokhu omuhle.

Isithwathwa imiqulu - siyini lesi anomaly?

Ngokokuqala ngqá ukubona lesi simanga semvelo, unquma ukuthi lokhu kudalwa umsebenzi wezandla zomuntu. Eqinisweni, ezifana ithrekhi noma imiqulu esonta Imvelo uqobo lwayo. Lena ezingavamile mkhuba Meteorological. Isithwathwa imiqulu kudala umoya, ukugibela iqhwa inqobo nje akusho pick up in nobukhulu. Ngokuvamile lezi izingcezu abe ukuma cylindrical, kodwa zikhona ezehlukile. Lesi simo esiyingqayizivele sibangelwa kungabonakala nasemkhakheni kuphela ezindaweni nge gusty nomoya onamandla, ukukhanya iqhwa elina kuphela ezindaweni ezivulekile. imiqulu Snowy phenduka asemaqeleni njengoba imiphongolo awunalutho. ubungako bawo ongafinyelela cm 30 ububanzi futhi cm 30 ububanzi. Eqinisweni, enkundleni eneqhwa singenzeka ngesikhathi esifanayo amakhulu imiqulu ehlukile. Ngamunye wabo kwesokunxele nokuncane - uhlobo ithrekhi elikhombisa trajectory of indlela siwela. Isithwathwa imiqulu zivame imiswe phakathi ukudlula iziphepho ebusika, lapho umoya iqhwa eqinile futhi fresh. Amazinga air kumele kube esondele ku-zero.

Inqubo ukwakha imiqulu seqhwa

Lokhu kwenzeka ngale ndlela: womhlaba kumele embozwe ungqimba phansi ice noma iqhwa igcwele ubudala, kulesi simo, falling iqhwa ne ungqimba ecashile babe adhesion abampofu. Isendlalelo engezansi kufanele ibe lokushisa emibi engapheli yabezindaba engenhla - omuhle (kancane ngenhla zero degrees). Khona-ke iqhwa fresh uzoba "tack" okusezingeni eliphezulu. Amazinga elikhulu ubhekwa degrees ezimbili, futhi ungqimba aphansi plus ezimbili - i-elingenhla. Gusty umoya kufanele ibe Isivinini okukhulu kuka-12 m / s. roll ukwakha iqala lapho umoya "umbe" ucezu iqhwa. Ngaphezu kwalokho, izigaxa elincane akhiwa, edonsa enkundleni ngaphansi kwethonya umoya, ezuza kusukela imitha ngalinye ezikhulayo ungqimba kweqhwa ezimanzi. Lapho umqulu sinzima kakhulu, kuzoyeka. Ngakho ukuthi lingakanani incike emoyeni ukugeleza rate.

Amaqiniso ethakazelisayo iqhwa

Lweqhwa 1. 95% emoyeni. Ngenxa yalokhu-ke ewela kancane kakhulu, ngesivinini 0.9 km / h.

2. Umbala omhlophe zeqhwa ngenxa yokubakhona emoyeni oyiyo. Kanjalo imisebe yokukhanya kubonakala kusukela imingcele ice crystal nge emoyeni futhi abahlakazekile bengaba.

3. amacala falling umbala iqhwa sabhalwa emlandweni. Ngakho, ngo-1969 e-Switzerland wawa iqhwa omnyama, futhi ngo-1955 e-California - Green.

4. ezintabeni eliphezulu Antarctica ukwazi ukuhlangabezana iqhwa pink, obomvu, violet, umbala ophuzi onsundu. Lokhu lula isidalwa - chlamydomonas iqhwa, okuyinto ihlala iqhwa.

5. Lapho eqhwa awela emanzini kwenza eziningi ephezulu imvamisa umsindo. Endlebeni yomuntu akakwazi ukubamba, kodwa izinhlanzi, futhi uma ukholwa ukuthi ososayensi, awufani kubo okuningi.

6. Ngaphansi kwezimo ezivamile, iqhwa liyancibilika ezingeni lokushisa zero degrees Celsius. Nokho, lapho ehlaselwa kwelanga, futhi kungaba shabalala at okushisa ngezansi zero, ngaleyo ndlela ngokudlula ewuketshezi.

7. Ngo-iqhwa ebusika ibonisa kusukela komhlaba kuze kube u-90% kwelanga, kanjalo hhayi sivumele yona kulungele.

8. Ngo-1987, e-Fort Okuthile (USA) baloba izinhlayiya zeqhwa enkulu kunazo zonke emhlabeni. Ubukhulu bayo kuyinto 38 cm.

Ekuphetheni

Lapha sibona alungise lo mkhuba sezulu, okuyinto ngakho kancane ukuchaza encyclopedia izichazamazwi. Manje siyazi izinga lokushisa lapho iqhwa liyancibilika, into, njani, nini futhi kungani kukhona iqhwa imiqulu nokunye okuningi aphathelene nalelo Ummemezeli amahle engumngane ebusika.
