A abun da ke ciki na yanayi

The Earth ta yanayi ne mai iska ambulan duniyar tamu, wanda ya hada da iskar gas da kuma impurities kamar ƙura, gishiri, ko ruwa na konewa kayayyakin, da adadin su ba m, da bambanci ga gas taro. La'akari daki-daki, abun da ke ciki na yanayi gas a matsayin mai yawan nitrogen - 78% Oxygen - 21%, xenon - 8.7% hydrogen - 5%, nitrous oxide - 5% helium ne ma - 4.6%, Neon - 1.8 %, methane - 1.7% krypton - 1.1% argon - 0.9%, ruwa - 0.5% da carbon dioxide - 0.03%.

A abun da ke ciki na yanayi ya hada da ruwa tururi, wanda dabam a lokacin da sarari kuma a tsakiya a cikin troposphere. Yana da ikon canja da carbon dioxide, da abun ciki dogara a kan mutum da kuma rayuwar da shuka. Aerosol barbashi samar da ayyukan mutane, sukan samu a cikin troposphere kuma a wata babbar tsawo, amma a karshen harka su ne a kananan allurai.

Saboda haka, abun da ke ciki na yanayi dabam dangane da tsawo. A yadudduka da suke kusa da qasa, da yawa na carbon dioxide ƙaruwa da oxygen - an rage. A wasu wurare da shi qara yawan methane da sauran gas da taimakawa wajen halakar da lemar sararin samaniya Layer, bayyanar da greenhouse sakamako da kuma acid ruwan sama. Game da 10% na impurities cikin yanayi a sakamakon halitta tafiyar matakai. Alal misali, volcanic eruptions toka fada cikin shi, sulfuric da sauran acid, kazalika da guba gas. Har ila yau, da sulfur tushen da aka rubabben ragowar shuke-shuke, seawater droplets da gandun daji gobara. Bugu da kari, 'yan inganta saki VOC (maras tabbas gudanar da mahadi). Sauran 90% na impurities, wanda wani bangare ne na yanayi da ya fada a sakamakon adam aiki. Wannan na iya zama, misali, hayaki watsi, yashewa, sharar gida ajiya da sauransu.

Ya kamata a lura da cewa yanayi yana da biyar yadudduka, da iyakoki wanda aka ƙaddara da zazzabi canje-canje, dangane da bambance-bambance a sha na radiation.

Saboda haka, m Layer (troposphere) na'am da gas daga ƙasa surface. Troposphere ruwansa da biyu main hurawa aka gyara, nitrogen da oxygen. Har ila yau, wannan Layer yana da babban yawa daga aerosols da tururi sunã gudãna danshin daga surface na teku ruwa.

Wannan ne ya bi da stratosphere, wanda yana da irin wannan abun da ke ciki da troposphere. Duk da haka, a nan da adadin ruwa tururi a dubu sau kasa, da kuma lemar sararin samaniya ne dubu sau mafi girma.

Bugu da kari, da abun da ke ciki na yanayi ya kunshi daban-daban abubuwa da ƙazantar da shi, kuma suna da wani sakamako a kan cutarwa rayayyun kwayoyin halitta. Ka yi la'akari da wasu daga cikinsu.

1. Sulfur dioxide jefarwa cikin yanayi da danshin na teku ruwa, watsi gas da sauran halitta matakai, kazalika da konewa na man fetur. Akwai shi reacts tare da ruwa tururi samar sulfuric acid.

2. Carbon dioxide kafa ta konewa na itace man fetur da kuma taba, kazalika da wani ciki konewa engine.

3. VOC (isoprene, terpene da methane) da aka kafa saboda ayyukan chemical, thermal ikon shuke-shuke, kazalika da danshin danshi a cikin shinkafa plantations ko Marshes.

4. oxide (dioxide) nitrogen da aka kafa tare da wani rashi na oxygen a konewa na man fetur, da kuma lokacin da babban adadin na shaye gas da kuma watsi a thermal ikon shuke-shuke.

5. Photo-oxidants (PAN, formaldehyde, lemar sararin samaniya) samar a sakamakon sinadaran halayen faruwa tare da sa hannu na hasken rana radiation.

Saboda haka, a cikin yanayin duniya da shi ya hada da babban yawan daban-daban abubuwa da kuma abubuwa. Wasu daga cikinsu suna da muhimmanci don kula da ayyukan kwayoyin a duniya, wasu wasa domin su pernicious rawa, bayar da tasu gudunmuwar ga halaka su. Saboda haka wajibi ne don tabbatar da cewa yanayi ba samu manyan yawa daga cutarwa abubuwa wanda shi zai iya hankali erode.
