Mene ne yanayi da kuma abin da yake da shi ga

Yanayi - shi ne "iska jacket" na Duniya, kamar yadda shi ne ake kira, kuma rayuwa a wannan duniya tamu ba tare da shi, dã sun kasance m. Wadanda cosmic halittu inda babu yanayi, ba zai iya gadara da rayayyun kwayoyin halitta. Wannan "gashi" na iska Tã 5 ya kai tan biliyan, kuma daga gare mu dauki oxygen da kuma shuke-shuke numfashi carbon dioxide. Wucewa ta hanyar shi neutralized hallakaswa ƙanƙara na da wani ɓaɓɓake daga sarari, kuma da lemar sararin samaniya balan-balan - ceton mu daga ultraviolet radiation da sauran. To, abin da yake cikin yanayi? Bari mu magana game da shi.

Yanayi - shi ne mai gaseous ambulan na wani wani sarari suKe jiki, star ko duniyar tamu. Gas da ke cikin yanayi ne aka gudanar da nauyi don haka da cewa da wuya a tantance inda ta fiber ƙare. Bayan da gas ne wani amorphous abu. Saboda haka, da yanayi da aka dauke su wani yanki a cikin abin da gas da kuma duniya juya integrally.

A yadudduka da yanayi

A yanayi da na kewaye da mu duniya, multilayered. Shi ne kamar kwai, wanda na kewaye da gwaiduwa gina jiki. A yadudduka ko ɓangare na yanayi, da daban-daban kauri da suke a daban-daban nisa. Bari mu dauki wani look at su.

A troposphere. Wannan "food weather." Its kauri ne game da 15 km. A nan, duk ba tare da tsayawa dabba ba a kanta, dumi da kuma sanyi iska gudana an gauraye, game da shi, kafa girgije, hazo, girgije.

Stratosphere. A wannan Layer, 25-30 km m, a cikin sama ɓangare tara lemar sararin samaniya. Wannan gas Layer, wanda kauri ne sosai kananan, yana da muhimmanci ga Duniya. Amma lemar sararin samaniya kullum ana halaka saboda da yanayi na daban-daban maras so sunadarai.

A mesosphere. The ball farawa daga wani tsawo na 50-55 km, shi ne game da 80 km sama da ƙasa. A wannan lokaci, tare da karuwa a tadawa, da kuma zafin jiki da yistin.

Thermosphere ko nanospheres - fathomless expanses na ionized gas. A wadannan wurare iska karkashin mataki na haskoki daga sosai sparse sarari, yana da babban lantarki watsin. Yana da yake a wadannan high yanayi yadudduka bayyana Aurora.

sinadaran da abun da ke ciki

Da yake amsa tambayoyi game da abin da yake cikin yanayi, shi wajibi ne don la'akari da abun da ke ciki. Saboda haka, shi ya kunshi cakuda 10 daban-daban gas, tsakanin wanda mafi girma a adadin nitrogen (78%), oxygen ya kamata a bi (21%). Ya zauna 1%, kuma a nan muhimmiyar rawa da majalisa ta zauna argon, karamin yawan carbon dioxide, Neon, kuma helium. Gas yanayi - shi ne inert sinadaran abubuwa, kuma a mayar da martani, ba su zo da wasu sinadarai. Kuma sosai kankanin rabo a cikin yanayi, sulfur dioxide, carbon dioxide, ammonia, lemar sararin samaniya (gas, oxygen alaka), kazalika da ruwa tururi.

Bugu da kari ga wadannan abubuwa, kuma atomosfere dauke da extraneous sinadaran: hayaki gaɓũɓuwa, gaseous gurbatawa, ƙura, gishiri da kuma volcanic ash.

Gurbacewar

Tare da tambayar abin da yanayin duniya, shi ne ya dace kuma ga matsalar gurbatawa na mu "iska jacket". Babban kafofin gurbatawa ne Enterprises na man fetur da kuma makamashi kansu, masana'antu, zamani sufuri. Dukkan abubuwa masu cutarwa zauna 80% na watsi da sulfur dioxide, hydrocarbons, carbon oxides, nitrogen da daskararru. Sau da yawa mutane ba su gane cewa wannan yanayi da kuma yadda muhimmanci shi ne a rayuwar duniya tamu. Mun koya cewa cikin iska kawai ne, kuma ayan amfani da iska ambulan kamar yadda so.
